▎ 摘  要

NOVELTY - Producing coated silicon material, comprises (a) providing a first solution containing 0.15-0.35 wt.%, preferably 0.2-0.3 wt.% difenoxide and remaining solvent for difenoxide, (b) providing a silicon material, (c) spraying the first solution on the silicon material, and drying, (d) providing a second solution containing graphene and 0.08-0.18 wt.%, preferably 0.11-0.15 wt.% delorazepam as an additive, and (e) coating the silicon material with the second solution to completely cover the surface of the silicon material. USE - The method is useful for producing coated silicon material as anode material in a metal-ion battery cell (claimed). ADVANTAGE - The method minimizes aging of electrodes with the silicon material, and improves electrochemical resilience of the electrodes.
