The difference between polymer battery and lithium battery

by:UFO      2020-05-19
Polymer lithium battery generally refers to polymer lithium ion battery, according to different lithium ion battery electrolyte materials used, the polymer lithium ion batteries are divided into liquid lithium ion battery and lithium ion battery or plastic lithium ion batteries. Do you know what is the difference between polymer lithium battery and lithium battery? The following and see it.

a, polymer lithium battery and lithium battery difference between

relative to lithium ion batteries, lithium polymer battery characteristics are as follows: 1.

No battery leakage problems, its inside the battery does not contain liquid electrolyte, the use of colloidal solids.

2。 Can be made into thin cells: in 3. 6 v400mah capacity, its thickness can be thin to 0. 5mm。

3。 The battery can be designed into various shapes.

4。 Batteries can be bending deformation: polymer battery maximum bending around 900.

5。 Can be made into a single high voltage: liquid electrolyte battery only can get high voltage with the number of batteries series, polymer batteries.

6。 As there is no liquid itself, can be made within the single star multilayer combination to achieve high voltage.

7。 Capacity will is more than double that of the same size of lithium ion batteries.

2, polymer lithium battery life

the correct way of saying: li-ion battery life and charge cycle times, and there is no direct relationship between charging times.

simple to understand, for example, a piece of lithium electricity on the first day only half of the battery, then charge for it. If so, the next day with half of the charge, the total charges down, it can only be counted as a charge cycle, instead of two. Often, therefore, may be charging after several times to complete a cycle. Charging each completed a week period, the power will reduce a little. Decrease rate is very small, however, the high quality of battery charge cycle for many times, still will retain 80% of the original electricity, a lot of lithium electric power products after two or three years later still in use, it is for this reason. Li-ion battery life, of course, to eventually need replacing.

li-ion battery life generally recharge from 300 ~ 500 period. If a completely discharge to provide power for Q, if you don't consider charging each cycle after power decreases, the lithium electricity within its life can provide a total or replenish the Q - 300 500 q of power. From this we know that if each use 1/2 is filled, you can charge 600 - 1000 times; If every time with a third charge, translates to 900 ~ 1500 times. By analogy, if the random charging, the number of times. In a word, no matter how to charge, added into a total of 300 q and 500 q power that is constant. So, we can understand like this: the lithium battery life and the total charge capacity of the battery, and charging times. Deep feed deep and shallow shallow charge for the influence of the li-ion battery life.

in fact, shallow shallow fill more beneficial for li-ion battery, only if the products do calibration for lithium electricity power supply module, have a deep deep filling necessary. So, the use of lithium electric power supply of the products don't have to be constrained in the process, all for first and charge at any time, don't have to worry about life.

if the above specified operating temperature, namely above 35 ° C environment using li-ion battery, the battery power will continue to reduce, the battery power supply time won't be long as usual. If at that temperature, but also for charging equipment, that will be more damage in the battery. Even in the hot environment of storage battery, will inevitably cause the corresponding to the quality of the battery damage. So, try to keep in good operating temperature is a good way to extend the service life of lithium-ion battery.

if in low temperature environment, namely 4 ° C below used in li-ion battery, also found that the use of the battery time reduced, some mobile phone original lithium electricity even in low temperature environment not to electricity. But don't worry too much, this is just a temporary condition, different from the use of high temperature environment, once the temperature rises, heated, the molecules in cell, restore to the previous power at once.

to take maximum effectiveness of lithium ion battery, you need to use it frequently, make the electronic always in the lithium electricity flow state. If you don't often use lithium electricity, be sure to remember recharge lithium electricity to complete a cycle, a month for a power calibration, the deep deep filling a
