FIELD: electricity.
SUBSTANCE: porous lithium anode contains a current collector made of metal, on the surface of which a multilayer coating containing three layers is applied. The inner layer applied to the current collector is made of a porous carbon matrix containing vertically oriented carbon nanoparticles. The middle layer deposited on the inner layer is made of metal, and the outer layer deposited onto the middle layer is made of metallic lithium.
EFFECT: invention allows to increase the specific capacity and the number of the battery recharging cycles, to reduce dendrite formation and overvoltage.
