Advancement in Battery Technologies

BatteryInnovations in technology embody advance materials, nanotechnology and improved battery style. There is great demand for batteries that are smaller, last longer, and are more powerful than batteries of the past. Today, researchers are pushing the design capabilities of batteries, leading to the invention of latest applications. They’re additionally finding ways to beat some of the largest technological barriers in energy storage, as well as capability, charge time, weight, and material price, while at the same time reducing environmental risks posed by the chemicals that are utilized in batteries.

Among the goals of the research is to make a battery which would provide electric cars the range similar to that of the cars with internal combustion engines. Some research projects are working towards developing a more robust lithium-ion battery, whereas others are exploring the opportunities created by the application of advanced materials like graphene. Lithium ion batteries, that presently lead the market place for advanced batteries in applications starting from consumer electronics to electrified transportation, represent a major step beyond typical lead-acid technology.

With each incremental improvement of the battery, the doors swing open for brand new products and increased applications. It’s the virtue of the battery that gives us with the freedom of being disconnected from home and work place. The higher the battery gets, the biggest our mobility and freedom will become.

Current analysis incorporates new materials and structures that will permit batteries to store and discharge energy in entirely new ways. Scientists are developing a unique style of battery called as lithium-air. Similar in structure to the lithium-ion battery, lithium-air technology provides a porous cathode that supplies oxygen. The lithium-air battery has the potential to store five to ten times a lot of energy than conventional batteries. Scientific and engineering challenges remain in developing the technology however, and development is still a number of years away.

In the 1970′s a brand new “sealed” type lead acid battery was introduced into the marketplace. These batteries use the principle of “oxygen recombination” to avoid the loss of water and, therefore, the batteries will be sealed and never want watering throughout their lifespan. In these batteries, the oxygen evolved at the positive electrode is transported and recombined with hydrogen at the negative electrode to create water. Because of the utilization of new alloys within the construction of the batteries, there’s very little or no gassing, however a small quantity of pressure could build up. A unidirectional valve that vents the gases controls this pressure. Because of this feature, these advanced lead acid batteries are called valve-regulated lead acid (VRLA) batteries. Also, the acid in VRLA batteries is immobilized either in fiberglass mat separators or in a silica gel. For this reason spillage and leakage have been eliminated. VRLA batteries are very attractive because of their lack of maintenance necessities.

Together these and different developments in energy storage technology could sometime make our lives more convenient, whereas essentially changing the manner we use energy and conduct business.

Pros and Cons of Battery Technologies Used in Cameras – Choose the Right One for You

Like other portable consumer electronic devices digital cameras use batteries as their power source. In this article we will describe different battery technologies and their cons and pros. Armed with this knowledge you will be able to take into consideration the battery used when purchasing your next camera.

A camera usually supports just one type of battery either a disposable battery or a rechargeable one. The exception is cameras that are powered by standard AA, AAA or similar batteries. In most of these cases disposable and rechargeable batteries can be used interchangeably.

There are two battery types:

  • disposable batteries: can only be used once. They usually have a standard size and shape such as AA, AAA and so on. You can buy these batteries at most stores and once they are empty you simply dispose them (please help keep the environment safe and clean by disposing batteries only to special battery disposal containers).
  • rechargeable batteries: can be used multiple times. Some rechargeable batteries have a standard size and shape such as AA, AAA and so on. Such standard size batteries can be used anywhere that a disposable battery can. More often than not however rechargeable batteries have a proprietary shape and are compatible with just a few specific cameras. Once a rechargeable battery is empty you can place it in a special charger that will recharge it. The time it takes to recharge a battery, the number of times it can be charged and the life time of the battery are dependent on the technology used to build the battery.

There are pros and cons to using disposable or rechargeable batteries. The main advantage to using a disposable battery is that you can always buy a few to have with you to replace the ones that are empty and you can always get one in a store close-by in case you are stuck with empty batteries. The disadvantages to using disposable batteries are the cost of buying new batteries every times your batteries are empty, the capacity (in most cases a disposable battery will not last as long as a good rechargeable battery). On the other hand rechargeable batteries require only one purchase. When the battery is empty you can simply place it in its charger and after an hour or so you will have a fully recharged battery. The disadvantage is that if you run out of batteries during a photo shooting session or somewhere away from home or a power supply you can not just buy another battery. The solution to that problem is to buy one extra battery and to always carry it with you fully charged.

If your camera uses standard size batteries such as AA or AAA you can have the advantages of both disposable and rechargeable batteries. You can always use disposable AA or AAA batteries with the camera but you can also get a rechargeable AA or AAA battery and use it when convenient.

Rechargeable batteries technologies:

Different technologies are used in building rechargeable batteries. Look at the battery itself to find out what technology was used in most cases it will be written on a small sticker on the battery or somewhere on its packaging. The following are the most common technologies and some of their pros and cons:

  • nickel cadium: one of the oldest technologies. These batteries are inexpensive, they can be recharged fast and many times before they lose their capacity. On the downside they have a low capacity and have a “memory effect” – a “memory effect” means that the battery can not be recharged to its full capacity unless it is first fully discharged. This can be problem since in most cases you will want to make sure your battery regardless of its current state is fully charged before going on a photo shooting session. Some charges solve this problem by first discharging the battery and only then recharging it to its full capacity.
  • nickel metal hybrid: this technology is an improvement of nickel cadium. These batteries capacity is much higher up to 50% more. Although it still has a “memory effect” it is less noticeable than in nickel cadium batteries. On the downside these batteries can be charged less times before losing their capacity and they also discharge faster when not in use.
  • lithium ion: A new technology that solves many of the nickel technology problems. Lithium ion batteries have a higher capacity than even nickel metal. They have no “memory effect” at all (and thus regardless of their current state they can always be recharged to their fullest capacity). The downside is that they are more expensive than nickel batteries.
  • lithium polymer: the latest technology. These batteries have all the advantages of lithium ion and more. They have an even higher capacity and can also be easily manufactured in any shape or form. This allows for much smaller and lighter high capacity batteries and for batteries shaped to better fit the camera design.

In conclusion when choosing a camera and considering what batteries it uses you should first make a choice between disposable and rechargeable batteries. If you choose to get a camera that uses rechargeable batteries you should try to choose a battery that uses the latest technologies like polymer or lithium unless you have some special considerations.

AA Lithium Batteries – A Great Advance in Battery Technology

Lithium batteries are made in two different types. One is the lithium metal battery which is manufactured using lithium metal. This is not rechargeable and can be used to replace alkaline batteries in your electronic devices. It is particularly handy in the very popular AA size which powers so many devices. Lithium batteries have much longer life and higher capacity then alkaline batteries.

The other type is the lithium ion battery. This is made from lithium compounds rather than the metal itself. These compounds are much more stable than lithium metal and provide an excellent power source which can be recharged at least 500 times. Lithium ion batteries are more expensive than alkaline or lithium metal varieties but due to the fact that they can be recharged so many times they are in fact very economical.

Lithium ion batteries are smaller and lighter than other rechargeables and run at a higher voltage. As a result of the higher voltage many devices can be powered with only one lithium battery, rather than using several of lower voltage. They will also will keep their charge for longer periods and can remain at a high charge level for a number of months.

Due to their complex construction, and smaller manufacturing numbers, lithium ion rechargeables are considerably more costly than most others. It is likely that this price will become lower as popularity increases and manufacturing volumes rise. They are not manufactured in the popular AA, C and D sizes. The reason for this is that they are made in a range of different shapes and sizes to fit particular devices. Each then requires its own special charger. They are not available in standard sizes due to the fact that they must not be recharged with standard battery chargers which are different in voltage.

Standard lithium metal batteries are made in the normal AA, C and D sizes, and can be used to power any device which uses these sizes. They have long shelf life and long usage life and are excellent power sources. They can be used in any electronic device which uses alkaline batteries and will last longer.

Tips On Mobile Phone Battery Protection and Maintenance

Battery supports to mobile phone activities, when power off, mobile phones are of no use, no messages, no income calls, and all activities cannot be used. Battery is the most indispensable part of a mobile phone, and its maintenance and protection are very important.

Battery technology never stops developing. From nickel cadmium battery in early stage, to nickel hydrogen battery and lithium hydronium battery, the battery ingredient technology is updated. Not only consider the power and battery life, but more eco factors.

Maintenance should be done when you recharging your cell phone battery.

1. Use original or well-reputed brand chargers, and use special charger for lithium hydronium battery. The charging time must be controlled in 24 hours because recharge time is not the longer, the better, and long time charging may cause dangerous.

2. After 3 to 5 times completely charge and discharge circles, new batteries’ internal chemicals are able to active and achieve the best use. So after buying a new cell phone, pay more attention on the first three or five recharge helps your battery gets a good beginning and work well in the future, 12 to 14 hours is appropriate charge time.

3. Different kinds of batteries have different tips. Nickel cadmium batteries have memory feature, so before you recharge a nickel cadmium battery, you must be sure that its power is completely run out and don’t cut off the power during recharging. Lithium hydronium batteries, in the opposite, have no memory and can be charged freely. But we should have a common sense that battery life is inversely proportional to charging times.

4. Avoid using universal charger. It is no doubt that universal charger is convenient than seat charger, no matter in carry or charge, and it seems that universal charger is more effective and can charge our batteries quickly. Actually, this is a wrong idea and this opinion only notice the result but doesn’t care much on battery protection. Your battery will be no longer available if you charge it by a universal charger too much. So if you want the battery life be longer, use original seat charger for original battery.

These tips above are methods to protect batteries from recharging; sometimes people doubt that they have made good protection on recharging batteries, why standby time is short. It is related to the capacity of battery and the use of mobile phone. To maintain your battery life time longer, you should know that your cell phone has many extra functions, such as GPS, Bluetooth, multi-media, camera, network, etc. These performances consume power faster than just make phone calls and send message, so if you are not apply some functions such as WiFi and Bluetooth, switch off them.

Getting more Battery Time from your Digital Camera Battery

Like other portable consumer electronic devices digital cameras use batteries as their power source. All batteries have one major drawback: they only last for a limited time. In this article we will explain what camera features consume the most energy and how you can squeeze more life time out of your digital camera battery.

There are many types of battery. Your digital camera might be using disposable batteries or maybe it uses rechargeable ones. Rechargeable batteries use a variety of technologies such as nickel cadmium, lithium ion or lithium polymer. Battery technology has advanced in the last years but batteries life time is still considerably short. It is very frustrating to come across a great photo opportunity just to find out that you have run out of batteries.

When it comes to power consumption not all digital camera features are equal. Some of the digital camera greatest features are high energy consumers. By knowing which features consume the most energy you will be able to avoid or minimize using those features save energy and get more life time from your batteries.

The biggest energy consumers in a digital camera are the LCD screen and the motors that move the mechanical components of the camera such as the lenses when focusing or zooming. Digital cameras allow viewing of photos that were just taken on a small LCD screen. Some of them also allow shooting photos using the LCD instead of the traditional viewfinder. An LCD screen consumes relatively a lot of energy. This is the reason why all digital cameras turn off the LCD after a certain amount of time of no usage.

The other big energy consumers are the motors. Digital cameras have motors the move the lenses either to change the zoom or to focus. Motors consume relatively a lot of energy when moving the digital camera optical components. And finally the flash is a big energy consumer too. Shooting photos using the flash consumes more energy that shooting photos without flash.

So what can you do in order to minimize power consumption and get more life time from your batteries?

  • Turn off the LCD and use the viewfinder: Use the optical viewfinder instead of the LCD for composing your photos. Using the camera menus disable the LCD by turning it off. Since the LCD consumes a lot of energy every time you are using it to take a photo or to look at your objects and compose a photo you are wasting energy. Only use the LCD when you must for example when taking an overhead photo when the optical viewfinder is not usable.
  • Minimize photo previewing: The LCD consumes a lot of energy. When you preview photos on the LCD you are wasting battery. Only use the LCD to view photos when you need to do so for the benefit of the next photos shooting – for example to check if a composition was right or if the lighting was good. Do not use the LCD to view photos for fun or to show photos to others. Wait until you are on your computer or in your office or home to do that.
  • Do not use continuous focus when not necessary: Every time your camera focuses it consumers energy. The motors that move the optical components in order to focus consume a lot of energy. You can not avoid focusing of course but you can avoid focusing that is not necessary. For example your digital camera can be set to continuous or single focus. For moving objects such as in sport events continuous focus is used so your can stay focused on the object until you are ready to take the photo. In those cases as long as you press the shutter button half way down the camera will continue to focusing on the object. To save energy minimize that time to the minimum necessary. For example if you plan to shoot a photo of a runner at point A only press the shutter when he gets close to that point. Holding the shutter button down and following the runner for a longer time than needed to capture him at point A wastes a lot of energy.
  • Do not press the shutter button half way down for no reason: Every time you press the shutter button half way down and do not take a photo you waste energy. When pressing the shutter button half way down the camera goes through a series of processes getting ready to shoot a photo. It focuses the lenses it wakes up electronic components and gets the flash ready if needed. Avoid pressing the shutter half way down when you do not plan to shoot a photo.
  • Carry another battery: Two batteries have twice the energy as one. Carry an extra battery if you are planning for a long shooting session or if you are not sure how many photos you will shoot and how long you will be away from your charger. Some photographers always carry an extra battery with them – batteries are very small and light and carrying an extra one is really not a burden. One thing to remember when carrying an extra battery is to always make sure that you are carrying an extra battery that is fully charged there is no use in carrying an empty battery. Batteries tend to lose their charge even if they are not used so if you are carrying an extra battery for a few days or more remember to recharge it even if you did not use it.
  • Recharge whenever you can: Charge your battery (or batteries if you carry an extra one) at least once a day or whenever you are back to your office, home or hotel. Even if you did not take many photos and you think the batteries have enough power in them it is better to make sure by fully charging them rather than to take the risk. You never know how long your next photo shooting session will be and when will your next recharge opportunity will be. Batteries slowly lose their charge even when not used so always recharge your extra battery too even if it was not used.
  • Plan for battery consumption: The most important thing is to plan for battery consumption. For example if you are leaving your office for a short photo shooting session of an hour you are not going to have any battery issues. In such cases you can ignore all the guidelines and just shoot photos freely in the way that is most convenient to you. If you are going out for a long day of photo shooting in scenarios that require flash and maybe continuous focusing (just as shooting a sports event) – plan ahead for power consumption take an extra battery or maybe two refrain from using features that are not necessary for your session such as previewing photos on the LCD or using the LCD as a viewfinder.

In conclusion until battery technologies improve to the extent that battery life is so long that it practically lasts forever you will have to be conscious about how you use your digital camera in respect to power consumption. Following a few simple guidelines can significantly improve power consumption and make your batteries last longer.
