What Are The Classifications Of Energy Storage Batteries?

The common energy storage battery is lead-acid battery (lithium-ion energy storage batteries with lithium iron phosphate as the positive electrode material are gradually being developed).
Energy storage batteries are divided into the following three categories:
1. Exhaust type energy storage lead-acid battery - The battery cover has a device for replenishing liquid and releasing gas.
2-valve regulated lead-acid batteries for energy storage - each battery is sealed, but each battery has a valve that allows gas to overflow when the internal pressure exceeds a certain value.
3. Lead acid batteries for colloidal energy storage - batteries using colloidal electrolytes.
