Lithium Ion batteries were invented so long ago as 1912 by means of Gilbert N. Lewis, but it was a very long time before they were developed enough being launched on a majority market level. This happened inside early 1990’ s using Sony pioneering their business use.
Lithium Ion batteries have several benefits.
They can be constructed in lots of shapes and sizes, resulting in them being tailored to your available space in the product in which they can be used.
The batteries are much lighter than different equivalents, due to the character of the material plus the high open circuit voltage when compared to other batteries. This low weight can make it ideal in hand held and mobile phones for obvious reasons, and popular in these days of high tech inventions.
Another major advantage is that they cannot suffer from memory impact. This is the state, whereby other rechargeable energy, if not fully released before recharging, lose their maximum energy capacity after a while and thus hold much less charge.
They also will not have such a drastic do-it-yourself discharge rate as additional batteries – just 5% a month, compared with up to 30% each and every month in other battery kinds. However, Lithium Ion batteries are certainly not perfect, and there will be drawbacks.
One of these is that their time depends upon their time – and not some time from which they had been charged, or the number of times they've been charged. They begin to lose capacity gradually from your date of manufacture irrespective of the number of charging cycles they include. Therefore the manufacturing date is advantageous to know, e specially if you find a big time lapse from manufacture to utilised e.. g due so that you can storage.
Some Lithium Ion energy (such as laptop batteries) can certainly lose around 20% with their capacity per year, while stored at normal temperature ranges. However, when exposed so that you can prolonged higher temperatures, this figure can increase to as much as 35% per year. Another key factor is the charge levels – when stored moderately charged, these figures might be dramatically reduced.
This makes Lithium Ion batteries unsuitable for sure applications – such as back batteries.
The battery must by no means be discharged below some threshold, otherwise the battery are going to be damaged irreversibly. Therefore, the devices that use them have an integrated system to shut them down after the charge level meets which will minimum threshold. For the following reason, Lithium Ion batteries were created and manufactured specifically in the device they are to power and so are not available as common names batteries.
Having said this, there are some products available that have an integrated circuit to monitor the actual minimum charge level and even shut the battery along when it reaches who level. These are generally known as “ smart” batteries.
Tips on how to prolong the life from your Lithium Ion battery
- Charge the battery early and quite often, unlike other rechargeable energy.
- If you will not intend to use the battery for years, charge it to an even of approximately 40% with capacity.
- The battery must be kept cool. They might age faster at better temperatures, so keep as cool as it can be when not in make use of. They can be safely stored inside of a refrigerator for optimum avoidance of aging. (note: they mustn't be frozen)
- If the product you are using is frequently run from a mains power supply (e.. g laptop) in fact it is possible, remove the battery when you use mains power. This avoid the battery from being suffering from high prolonged temperatures which sometimes shorten it’ s lifestyle.
- Any steps to relieve the heat that the battery is exposed to will benefit it’ ersus lifespan.
- When choosing replacements, try to order a battery that has the actual shortest possible time through manufacture to retail. (though it usually is difficult to find outside this information).
In short Lithium Ion batteries can be a very versatile battery, ideal in lightweight applications but not subject to memory impact. However, they do degrade at higher temperatures so this means they are not the universal battery solution.
