How secondary battery works?

Question

Accepted Answer

Secondary batteries work by converting chemical energy into electrical energy.

Secondary batteries, also known as rechargeable batteries, can be charged and discharged multiple times.
They use chemical reactions to store and release energy.
Common types of secondary batteries include lithium-ion, nickel-cadmium, and lead-acid batteries.
During charging, the battery's positive electrode (cathode) accepts electrons, while the negative electrode (anode) releases electrons.
During discharging, the process is reversed, with the cathode releasing electrons and the anode accepting them.
Secondary batteries are widely used in portable electronic devices, electric vehicles, and renewable energy systems.
