Background

Solid state batteries are a battery technology. Unlike lithium ion batteries and lithium ion polymer batteries, which are commonly used today, a solid-state battery is a battery that uses solid electrodes and a solid electrolyte. Since the scientific community considers lithium ion batteries to have reached a limit, solid state batteries have recently been considered as batteries that can inherit the position of lithium ion batteries. The solid-state lithium battery technology adopts a glass compound made of lithium and sodium as a conducting substance to replace the electrolyte of the traditional lithium battery, thereby greatly improving the energy density of the lithium battery. Solid state batteries generally have lower power densities and higher energy densities. The solid-state battery is an ideal battery for electric vehicles because of its relatively high power and weight.

At present, solid-state batteries become new items for research and development of various large battery manufacturers and scientific research institutions in recent years due to the advantages of high energy density, high charging speed, long service life, good thermal stability, no low-temperature freezing and the like.
