Negative electrode and method of producing the same

Abstract

A method of producing a negative electrode includes a process of preparing granule particles containing a Si-based active material, a conductive material, and a first binder having an imide framework, a process of preparing a negative electrode mixture containing the granule particles, graphite particles, and a second binder having no imide framework, and a process of applying the negative electrode mixture to a current collector and performing drying, wherein the weight percentage of the first binder contained in the granule particles is 5% or more and 15% or less, and the granule particles have an average diameter of 50 μm or less.
