China best top 5 solid state battery manufacturers



The outbreak of the electric vehicle market has promoted the development of the battery industry. In recent years, solid state batteries have gained widespread attention due to their absolute advantages such as non-flammability and high energy density up to 1000Wh/kg.

Compared with liquid batteries, solid-state batteries have various performance advantages such as higher energy density, higher safety, longer cycle life, and better low-temperature performance. In terms of energy density, solid state batteries can achieve more than 400wh/kg, twice that of existing liquid batteries. Since there is no liquid electrolyte, the material system of solid state batteries can have more possibilities.


For example, metal lithium is used for the anode; safety issues such as liquid leakage and gas leakage can be further avoided, and the thermal stability of the battery is better; the pack level can simplify non-essential devices, thereby improving volume utilization. This article sorts out the top 5 solid state battery manufacturers in China, including CATL, BYD, Gotion High-Tech, Ganfeng Lithium and WELION, in no particular order, for your reference.
