SECONDARY BATTERY, NEGATIVE ELECTRODE AND METHOD FOR PRODUCING A NEGATIVE ELECTRODE

A secondary battery is provided and including a positive electrode and a negative electrode. A negative electrode includes: a negative electrode current collector; a first negative electrode layer provided on the negative electrode current collector and containing graphene; a lithium metal layer provided on the first negative electrode layer, containing lithium metal, and not including graphene; and a second negative electrode layer provided on the lithium metal layer and containing graphene. In a state in which the potential of the negative electrode is 0 V (vs Li/Li), the first negative electrode layer includes lithium alloy particles containing lithium and a metal that forms an alloy with lithium, and a mass fraction of the lithium alloy particles in the first negative electrode layer is larger than a mass fraction of the lithium alloy particles in the second negative electrode layer.
