Research on polymer lithium battery cycle life

With the increasingly severe global pollution, energy conservation and environmental protection has become from all walks of life advocated by the project, so, how to energy saving, environmental protection? Should people daily use products, products now on the market have a lot of environmental pollution, from the product management as the basis. In the battery market, lithium battery is a super star, with its long service life and charge and discharge completely, no memory effect, non-polluting characteristics quickly occupy the market, favored by consumers.

Because of the form lithium ion batteries electrolyte materials differ, lithium ion batteries are divided into polymer lithium ion batteries and liquid lithium ion battery. Liquid polymer lithium ion battery and lithium ion battery anode materials are the same, the working principle of the battery, and the electrolyte are different. Polymer lithium battery light weight, strong energy storage capacity, discharge performance is good and can cause a variety of shapes, and a longer life span. Polymer lithium battery electrolyte for a solid electrolyte, relative to the liquid lithium ion battery liquid electrolyte, polymer lithium battery can cause a variety of shapes to improve specific capacity of the battery.

How long is the lithium polymer battery life? International standard, the battery life does not come in through the time to say, but by cycles, namely complete after computing time, common lithium-ion batteries are between 500 to 800, A product polymer battery up to 800 times. So choose a good battery supplier quality is guaranteed, longer service life.

If use lithium ion battery in high temperature environment, such as the temperature of above 350 c, storage battery power will continue to decrease, which makes the service life of the battery will not as long as in normal temperature environment in the work time.In under the environment of high temperature to recharge the battery, the battery will be subject to a greater degree of damage, thus influence the service life of batteries.Even in a hot environment will cause varying degrees of damage to the battery charging, so you should try to avoid in high temperature environment to recharge the battery.If to recharge the battery in low temperature environment, such as lower than 40 c environment, also can cause damage to battery.

If not for a long time for polymer lithium ion battery, will reduce its life.Polymer lithium ion battery needs under the conditions of electronic long-term flow will reach its ideal life.Polymer lithium ion battery in the global commercial production technology is not very mature, now held by market share is not high.

At present, polymer lithium ion battery is higher than the market price of the liquid lithium ion battery, relative to the liquid lithium ion battery, its long life, safety performance is good, believe in the near future there will be a big rise in space.

The correct way of saying: li-ion battery life and charging 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.Each completed a charge cycle, 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.

The life of the lithium electricity 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 or replenish a total of 300 Q - 500 Q of power.From this we know that, if every time filled with 1/2, translates to 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.

Shallow put lightly, in fact, 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 lithium electricity, 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 is 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 electrons within the lithium electricity is always in a state of flow.If you don't often use lithium electricity, be sure to remember recharge lithium electricity to complete a cycle, a month to do a power calibration, the deep deep to charge.

How long is the life of a polymer lithium battery?Believe that the vast majority of consumers are heard, polymer lithium battery life is "500", 500 times more than the number of times, "dead" batteries.Small make up for the next 258 platform is to introduce how long is the life of a polymer lithium battery.

As a result, many friends in order to be able to extend battery life, each time to charge when the battery run out completely, so to really have a longer effect the battery life?The answer is no.Lithium battery life is "500", refers not to the number of charge, but a charge and discharge cycles.

A charge cycle means that all the power battery by full use empty, again by the empty into the full process, this is not the same as to charge., 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.Each completed a charge cycle, battery capacity will reduce a little.The power decrease rate is very small, however, the high quality of battery charge cycle for many times, still retains the original capacity of 80%, a lot of lithium electric power products after two or three years later still use as usual.The li-ion battery life in the final and, of course, is still need to be replaced.

The so-called 500 times, is refers to the vendor in the constant depth of discharge (e.g., 80%), the number of rechargeable 625 times or so, to 500 charge cycles.(80% * 625 = 500) (ignoring the lithium battery capacity reduction etc.)

Due to the various influence of real life, especially when charging the discharge depth is not constant, "500 charge cycles" can only be used as a reference battery life.

More than 258 enterprise service platform of small make up to collect summary how long is the life of a polymer lithium battery, hope can help you know more about polymer lithium battery.
