[0002] Solid-state batteries are a type of battery technology. Unlike the lithium-ion batteries and lithium-ion polymer batteries commonly used today, solid-state batteries are batteries that use solid electrodes and solid electrolytes. In solid-state ionics, solid-state batteries are batteries that use solid electrodes and solid electrolytes. Solid-state batteries generally have lower power density and higher energy density. Due to the high power-to-weight ratio of solid-state batteries, they are ideal batteries for electric vehicles. Generally, most solid-state batteries do not have an assembly structure and are powered by welding in actual applications. This direct welding method is not conducive to improving the assembly efficiency of the system where the array battery module is located, and is also not conducive to the subsequent maintenance of the product, thereby reducing the use effect.
