FIELD: electricity.
SUBSTANCE: invention relates to an accumulator with a cathode and a porous anode, having improved lithium diffusion kinetics and surface conductivity. Anode contains an active anode material lithiated with a lithium source. Lithium particles from the lithium source are doped or intercalated with the active anode material during diffusion to form a three-dimensional porous frame. Porous frame provides reduced destruction of electrode due to increase in volume.
EFFECT: higher safety, efficiency and fast charging.
