The weather is getting hot, do not put lithium batteries on the car in summer

With the seasonal changes, the temperature all over the country began to gradually rise, a hot summer is coming, so what are the matters needing attention to using batteries in the case of high temperature? In order to use lithium battery more safely and efficiently, today Mr.Yammu New Energy tube to introduce the matters needing attention to the use of batteries in the next summer.

There are many people who like to carry a charger laptop in their car, which is very dangerous. According to the introduction of Mr.Yamamu, high temperature will reduce the capacity of lithium ion batteries, especially now the internal design of digital products is compact and the space is narrow. Heat is generated between the components and affects each other. Too high temperature will lead to the internal temperature of lithium battery instability, especially lithium battery in the process of charging and discharging, itself will also produce heat. Will further increase the temperature of the battery.

Mottcell new Energy tube said that at high temperature, the lithium electrolyte of lithium ion battery LiPF6 will occur thermal decomposition of PF5, and the water in the electrolyte further hydrolysis of HF. At the same time, lithium manganate in lithium batteries will decompose the reaction and form a disordered chemical structure, further leading to the reduction of lithium ion mobility, and eventually lead to battery failure. The manganese ions from the positive electrode will be dispersed by the electrolyte to the negative electrode and then deposited on the negative electrode, leading to the deterioration of the performance of the negative electrode.

The high temperature will change the internal pressure of the battery, the internal pressure of the battery will lead to leakage, and the properties of the electrolyte, including the shape of the diaphragm, will also change, which is likely to shrink. This leads to an internal short circuit, serious may cause thermal runaway. Especially in the summer, the car itself is a metal shell, plus the interior is small in a confined space, the temperature climbs very fast. Especially after the exposure to the temperature is often higher than the temperature outside the car. So especially remind the majority of owners not to lithium batteries and appliances with batteries in the car for a long time.

For lithium batteries whose special products must work in high temperature environment, Shenzhen Mottcell New Energy Technology Co., Ltd. has developed a variety of models of high temperature resistant lithium batteries to meet the application of special scenarios. To ensure the safety and reliability of the lithium battery. Welcome customers to the factory to negotiate cooperation.
