Description
H01M encompasses electrochemical energy conversion devices and processes that directly transform chemical energy into electrical energy. This subclass covers batteries, fuel cells, supercapacitors, and related electrochemical systems across all chemistries and configurations. It includes cell and battery design, electrode materials, electrolytes, manufacturing processes, performance testing, and safety features for primary, secondary (rechargeable), and specialized energy storage applications.
