Abstract

A lithium-ion secondary battery includes at least a positive electrode and a negative electrode. The negative electrode is porous. The negative electrode includes a carbon fiber aggregate and a polymer film. The carbon fiber aggregate is an aggregate of a plurality of carbon fibers bound together in a three-dimensional fashion. The polymer film covers a surface of each of the carbon fibers. The positive electrode includes a group of particles and an electrolyte solution. The group of particles is dispersed in the electrolyte solution. The group of particles contains a positive electrode active material and a conductive material. Pores that are present within the negative electrode are filled with the positive electrode. The polymer film is swollen with the electrolyte solution.
