▎ 摘　　要

NOVELTY - Anode pole piece comprises a current collector (1), and an active layer (2) including silicon nanoparticles (4), and lithium metal located in porous carbon skeleton (3). The material of current collector comprises at least one of copper, nickel, titanium, molybdenum, iron, zinc, stainless steel, carbon and graphene. USE - The anode pole piece is useful in lithium-ion battery of electronic device (all claimed), preferably electric automobile and mobile electronic device. ADVANTAGE - The anode pole piece reduces volume change of the anode pole piece in the circulation process when utilized in lithium-ion battery, has uniform electric field, thus improving the uniformity of lithium deposition and inhibiting the growth of lithium dendrites, and improved safety, high energy density, large specific energy, high working voltage, low self-discharge rate, small volume and light weight, maintains the stability of the anode pole piece volume, and reduces the local current density, so as to improve the deposition shape; and effectively regulates the deposition position of lithium, so that lithium is preferentially deposited in the pores during the cycle performance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of anode pole piece in lithium-ion battery of electronic device.
