    • What is the difference between polymer lithium battery and ternary lithium

      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.

      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.

    • How to make the battery safer? Industry: gradual improvement is more reliable than subversion

      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
