All lithium ion batteries, whether in the past or in recent years, including lithium polymer batteries, lithium iron phosphate batteries and so on, are very afraid of internal battery short circuit, external battery short circuit, overcharge these situations.

According to the foreign media The Verge, batteries sometimes explode. Those explosion videos are scary, but scientists and startups have been working hard to build safer batteries. They are improving the battery design and testing new materials, hoping to solve the safety problem once and for all. But every method seems to have a trap, and the most practical solution at present may be the most boring. There are three strategies to improve battery: avoid using flammable liquid as solid battery; Make the battery module fireproof; Modify the existing functional characteristics of the battery slightly. At least as far as batteries are concerned, this change may come

Against the background of increasingly depleted oil resources and environmental pollution, electric vehicles have entered a period of rapid development. However, due to the high cost, short battery cycle life, short range and other problems of electric vehicles, further large-scale promotion of electric vehicles is also restricted.

The electrolyte is a conductive ionic conductor between the positive pole and the positive pole of the battery. It is composed of electrolyte lithium salt, high-purity organic solvent, necessary additives and other raw materials in a certain proportion. It plays an important role in the energy density, power density, extensive temperature applications, cycle life and safety performance of batteries.

、 Background of intelligent lithium battery At present, lithium-ion batteries have become popular in the market, and a large number of lithium-ion battery packs have adopted the form of multi cell series and parallel. Due to the individual differences of cells, it is impossible to achieve 100% balance between charging and discharging, so a complete set of charging management system is

With the rapid development of the global electronic information industry today, Vietnam's electronic and smart home appliance market is ushering in unprecedented development opportunities.
