Lithium Metal Anode for Batteries

However, the major capacity that dictates the energy density of the battery is the discharge capacity that depends on the cathode. This is because the electrical energy is obtained from the battery during the discharge process. On the other hand, the anode capacity dictates the total storage amount of Li ions during the charging process.
