How long is polymer lithium battery cycle life?

With the increasingly severe global pollution, energy conservation and environmental protection has become the project advocated by the world, so how to save the energy and how to protect the environment?We should begin with people daily used products.There are many environmental pollution products on the market now based on product management.In the battery market, lithium battery is a super star, with its long service life and charge and discharge completely, no memory effect and non-polluting characteristics,so that it quickly occupies 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 500, A polymer battery can reach 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.

Lithium polymer battery (Li - polymer, also known as the polymer lithium battery) : it is also a kind of lithium ion battery, but compared to the liquid lithium battery (Li - ion) with high energy density, miniaturization, ultra-thin, lightweight, and high security, and other obvious advantages, is a new type of battery.In shape, lithium polymer battery with ultra-thin characteristics, can match the needs of the various products, made into any shape and the capacity of the battery.The battery can reach the minimum thickness of 0.5 mm.The nominal voltage and Li - ion is nominal voltage of 3.7 V, no memory effect.

Polymer lithium ion batteries

Depending on lithium ion battery electrolyte materials used in lithium ion battery can be divided into liquid lithium ion battery (lithium ion battery, referred to as the LIB) and polymer lithium ion battery (polymer lithium ion battery, referred to as LIP) two kinds big.Is used in the polymer lithium ion battery cathode materials and liquid lithium ion is the same, the working principle of battery is almost the same.Their main difference is that the different electrolyte, lithium ion battery using the liquid electrolyte, polymer and polymer lithium ion battery with colloidal electrolyte instead.

Ordinary lithium ion battery when overcharge, short circuit, and so on and so forth occurs, the battery internal temperature, the anode materials decomposition may occur, the phenomenon such as the cathode and electrolyte materials is oxidation, resulting in gas expansion and the battery internal pressure increase, when the stress reaches a certain degree after explosion may appear.Polymer lithium ion battery for use the colloidal electrolyte, not because the liquid boiling and produce a large amount of gas, thus eliminating the possibility of explosions.

At present domestic most polymer battery is just soft package battery, aluminum-plastic film is applied to make shell, but the electrolyte has not changed.The battery can also be thin, the low temperature discharge characteristic is better than polymer battery, and the material energy density with common polymer liquid lithium battery, battery, but because use the aluminum composite membrane, therefore is more light than ordinary liquid lithium electricity.Security, when just boiling liquid soft package of battery aluminum-plastic film naturally bulge or rupture, also won't explode.

Must pay attention to is that the batteries still can burn or expansion cracks, security is not foolproof.

Compared with liquid lithium ion batteries, polymer lithium ion battery not only high safety, at the same time also can thin shape is changed, any area with arbitrary shape etc, shell USES lighter aluminum-plastic composite membrane.However, the low temperature discharge performance may still have room for improvement.

Liquid lithium electricity

Because of the difference of each manufacturer's production process, the polymer li-ion battery on the market is divided into coiling () represented by SONY, Toshiba, folding plate (represented by TCL, ATL) of two different structure, but adapted to the demand of the specifications of the most under 4 mm thickness.Compared with liquid, the adoption of the polymer packaging of aluminum film is thinner and thinner than steel shell, aluminum shell, and the mode of production is different from liquid lithium electricity, polymer, the thinner the better production theory can produce 0.5 mm below the thickness of the battery.

Liquid lithium electricity on the contrary, the thicker the better production, less than 4 mm thickness of the battery is difficult to produce, even if produced, is clearly polymer Li-ion battery capacity, cost advantage.Consequently, the thinner batteries, polymer, the lower the cost of production, liquid production cost is higher.

But thicker on the specification of liquid lithium electricity supply chain mature, mature technology, high production efficiency, high yield, strong manufacturing cost advantages.From the point of the market, 5 mm, 6 mm thickness series of liquid lithium battery although than 3 mm, 4 mm thickness series battery capacity is much higher, but the price is much lower.Polymer in theory, in 5 mm, 6 mm thickness specifications on the material cost and liquid is close to, but at present the craft of 5 mm, 6 mm series battery costs a lot higher than the density of its liquid, therefore, in this specification and liquid form real competition, there are a lot of distance.
