PostSubject: This Pro抯 & Cons regarding Lithium Ion batteries.   Fri Oct 21, 2011 2:51 pm

Lithium Ion batteries were invented as long ago as 1912 by means of Gilbert N. Lewis, but it was quite a long time before they were developed enough for being launched on a standard market level. This happened within the early 1990’ s with the help of Sony pioneering their business oriented use.
Lithium Ion batteries have many advantages.
They can be constructed in a multitude of shapes and sizes, resulting in them being tailored to available space in the gps unit in which they should be used.
The batteries will also be much lighter than different equivalents, due to the type of the material and therefore the high open circuit voltage when compared to other batteries. This low weight causes it to be ideal in hand held and cellular phones for obvious reasons, and popular in these days of high tech machines.
Another major advantage is that they don't suffer from memory results. This is the circumstance, whereby other rechargeable electric battery, if not fully cleared before recharging, lose their maximum energy capacity with time and thus hold a lot less charge.
They also don't have such a drastic self applied discharge rate as many other batteries – just 5% monthly, compared with up to 30% every month in other battery models. However, Lithium Ion batteries aren't perfect, and there really are drawbacks.
One of these is that their generation depends upon their age – and not the moment from which they happen to be charged, or the number of times they are charged. They begin to lose capacity gradually on the date of manufacture irrespective of the length of charging cycles they possess. Therefore the manufacturing date pays to to know, e specially when there is a big time lapse from manufacture to being utilized e.. g due to make sure you storage.
Some Lithium Ion electric battery (such as laptop batteries) can certainly lose around 20% of the capacity per year, whenever stored at normal temperature. However, when exposed to make sure you prolonged higher temperatures, this figure can increase to as much as 35% per year. Another key factor is the charge levels – when stored in part charged, these figures could be dramatically reduced.
This makes Lithium Ion batteries unsuitable for several applications – such as back off batteries.
The battery must never ever be discharged below a particular threshold, otherwise the battery is going to be damaged irreversibly. Therefore, the devices that use them have a built in system to shut them down in the event the charge level meets who minimum threshold. For this approach reason, Lithium Ion batteries are intended and manufactured specifically for your device they are to power as they are not available as generic batteries.
Having said of which, there are some variants available that have a built in circuit to monitor the minimum charge level and shut the battery affordable when it reaches which will level. These are referred to as “ smart” batteries.
The best way to prolong the life of one's Lithium Ion battery
- Charge the battery early and infrequently, unlike other rechargeable battery packs.
- If you you should never intend to use the battery for a long period, charge it to a level of approximately 40% associated with capacity.
- The battery need to be kept cool. They can age faster at more significant temperatures, so keep as cool as is possible when not in utilize. They can be safely stored within a refrigerator for optimum reduction of aging. (note: they must not be frozen)
- If these devices you are using might be run from a mains power (e.. g laptop) and it's possible, remove the battery when utilizing mains power. This avoid the battery from being put through high prolonged temperatures that may shorten it’ s existence.
- Any steps to scale back the heat that the battery is the subject of will benefit it’ ohydrates lifespan.
- When acquiring replacements, try to obtain a battery that has the particular shortest possible time from manufacture to retail. (though it can be difficult to find away this information).
In short Lithium Ion batteries really are a very versatile battery, ideal in lightweight applications instead of subject to memory influence. However, they do degrade at higher temperatures which suggests they are not an important universal battery solution.
