In terms of materials used, the positive electrode materials of polymer lithium ion batteries are divided into lithium cobalt oxide, lithium manganate, ternary materials and lithium iron phosphate materials. The negative electrode is graphite, and the working principle of the battery is basically the same. The important difference between the positive electrode materials of polymer lithium ion batteries lies in the difference of electrolytes. Liquid lithium ion batteries use liquid electrolytes, and polymer lithium ion batteries use solid polymer electrolytes instead. This polymer can be dry or glued. At present, most of the polymer gel electrolytes are used.

Diaphragm 135 ℃ automatic shutdown protection, using internationally advanced Celgas2300PE-PP-PE three-layer composite membrane. When the temperature of the battery reaches 120 ℃, the membrane holes on both sides of the PE composite membrane are closed, the internal resistance of the battery increases, and the internal temperature of the battery slows down. When the temperature of the battery reaches 135 ℃, the PP membrane hole is closed, the battery is internally open, and the temperature of the battery is no longer increased, ensuring the safety and reliability of the battery.

The battery module can be understood as the intermediate product of the battery cell and pack formed after the lithium ion battery cells are combined in series and parallel, and the single battery monitoring and management device is installed. Among the three common lithium battery packaging forms, the single energy density of the soft package lithium battery is the most easy to achieve, but when it comes to module design, the task of considering the overall safety of the product is the most important, which can be said to transfer part of the cell activity to the module structure.

In the UAV industry, the term "fpv lithium battery" is often used. At this time, I believe many friends want to know what fpv is? This article will take you to understand what fpv is? At the same time, the demand for fpv lithium batteries is also large

In recent years, more and more new energy vehicles have entered people's lives. According to relevant data, by the end of 2020, the number of new energy vehicles in China has reached 4.92 million, accounting for 1.75% of the total number of vehicles, an increase of 1.11 million over 2019, or 29.18%. In addition, the growth of new energy vehicles has exceeded 1 million for three consecutive years, showing a trend of sustained and rapid growth, which indicates that the industry has a good development trend.
