company news about Impact of solid state battery: where is the direction of cobalt lithium enterprises?

Compared with lithium battery, solid state battery is superior to lithium battery in energy density, safety and cost. Solid state battery has higher energy density upper limit; due to specific structural differences, solid state battery has higher security; under large-scale production, the cost of solid state battery is expected to be lower than that of lithium battery.

At today's live online market conference hosted by SMM, Yuan Ye, new energy analyst of Shanghai Nonferrous Metals network, brought "the impact of solid-state batteries. Where is the direction of cobalt lithium enterprises?" In his keynote speech, Yuan Ye said that solid-state batteries will realize the transformation of all solid electrolyte and negative metal lithium, but the problems of conductivity, safety, stability and high cost still need to be solved. Enterprises in the fields of high nickel positive electrode, lithium carbonate and silicon carbon negative electrode will have new opportunities due to solid-state batteries, while electrolyte and diaphragm enterprises will have impact.

Recently, major auto companies have frequently released "black technologies" such as solid-state batteries, long-term battery life and fast charging. For example, on January 9, Weilai officially released a 150kwh battery pack, which can achieve an energy density of 360wh / kg and is scheduled to be delivered in the fourth quarter of 2022. Weilai will use solid-state batteries with a range of 1000km in new models in the next step; Toyota's solid-state batteries can realize charging for 10 minutes and a range of 500km, and Toyota plans to launch solid-state battery prototypes in 2022.
