FIELD: electricity.
SUBSTANCE: invention relates to the technology of producing metal anode materials for sodium-ion batteries (SIB) operating at high charge and discharge currents with high energy efficiency and specific energy intensity. Metal anode material of the sodium-ion accumulator is made of a current collector, on the surface of which there is at least one active layer made of at least one electrochemically active element selected from the group: Sn, Bi, Pb, Ag, Zn.
EFFECT: improved specific electrochemical characteristics of SIB.
