▎ 摘  要

NOVELTY - Manufacturing a lithium-ion storage battery involves providing a negative electrode adjacent to a positive electrode, which comprises a positive electrode current collector and a positive electrode active material layer. The negative electrode comprises a negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer comprises silicon particles and a binder. A silicon wire is formed from a first part of the silicon particles by heating after forming the negative electrode active material layer. The thickness of the negative electrode active material layer is smaller than a thickness of the positive electrode active material layer. USE - Method for manufacturing lithium-ion storage battery. ADVANTAGE - The lithium-ion secondary battery including the electrode can have improved reliability.
