Li-polymer batteries are a branch of lithium-ion batteries developed from lithium-ion batteries. Lithium polymer batteries are lithium-ion batteries that are completely solid or gel-like electrolytes. Aluminum-plastic composite film is generally used as the packaging material. Lithium-ion battery generally refers to the aluminum case battery. The electrolyte is a liquid and the outer packaging material is an aluminum case. Lithium polymer batteries are safer than lithium-ion batteries. The li-polymer battery is an upgrade of the lithium-ion battery.

Compared with ordinary lithium-ion batteries.
When ordinary lithium-ion batteries are overcharged and short-circuited, the internal temperature of the battery may rise. The cathode material decomposes, and the negative electrode and electrolyte material are oxidized. This leads to gas expansion and increased pressure inside the battery. When the pressure reaches a certain level, there may be an explosion. Li-polymer batteries, however, do not generate large amounts of gas due to liquid boiling because of the use of gel electrolytes. This eliminates the possibility of an explosion.

About the shell of the polymer battery.
The key to the greater competitive advantage of li-polymer batteries is their small size, relatively lightweight, and portability, making them the ideal green energy source for purchasers. The selection of li-polymer batteries must be within the scientific and reasonable voltage capacity range. More and more purchasers are seeking the perfect large capacity, ultra-high voltage. This idea and practice are completely wrong. It must be clear that the more energy that accumulates in a limited volume, the less manageable it is. The higher the voltage and the higher the capacity, the more difficult and the more the failure rate of the protection and equalization circuits. To better match the devices we use with Li-polymer batteries, it is important to look at the safety test certification of Li-polymer batteries. As follows.

In general, the first from the external li-polymer battery identification appearance to determine such as the manufacturer’s name, trademark name or trademark, style setting, and the battery should be identified expression.

On the other hand, it is necessary to pass tests such as impact, acceleration, vibration, thermal shock, thermal cycling test, and high-altitude simulation tests. The sample li-polymer battery does not explode or catch fire, there can be no perforation or leakage.

Next, you also need to take charge and discharge test, to understand from charge and discharge cycle, short circuit test, abnormal charging test, mandatory discharge test, overcharge, and so on.

At this stage, more and more li-polymer battery manufacturers in the battery export have CE certification marks, indicating that it meets the standards of safety, health, environmental protection, buyer protection, etc. In the European Economic Area market sales of goods is a mandatory certification, so we have to line the lithium battery strict judgment. To ensure that the use of equipment brought about by strong protection, avoid the use of the process of all the dissimilarities.

Our corporate values are to contribute to the progress of society. We provide li-polymer batteries and services to our customers, and will not be presumptuous because of large profits, not because of thin profits, and not for. We always insist on benefiting social progress as the value orientation and judgment standard of enterprise behavior.
