FAQs about Secondary Energy Storage Batteries
How does a secondary battery work?
A secondary battery (accumulator) stores energy in the form of chemical energy, which it then reconverts into electrical energy upon demand. It accepts energy in the charging cycle which forces an electrochemical change within the cell. The battery can then be discharged; the electrochemical changes are reversed and now occur spontaneously.
