A PUBLIC TREND
Solid-state lithium battery: the next generation of lithium battery technology
Solid-state lithium battery combines high safety and high energy density battery technology.
The fundamental feature is the replacement of a liquid electrolyte with a solid electrolyte.
The crucial technology is the innovative development of materials.
Fully replace all solid state batteries; partially replace solid state batteries.
Most traditional lithium battery applications can be replaced by safer solid-state lithium batteries;
Due to safety factors, some areas that cannot use traditional lithium batteries are also potential markets for solid-state lithium batteries;
High safety, high energy density solid-state lithium batteries will greatly promote the trend of electrification in more fields.
