Abstract:
The object of an exemplary embodiment of the invention is to provide a secondary battery with a high performance in which the generation of the swelling can be suppressed and in which the cycle property is excellent. An exemplary embodiment of the invention is a secondary battery, comprising an electrode assembly in which a positive electrode and a negative electrode are oppositely disposed, an electrolyte liquid, and a package which encloses the electrode assembly and the electrolyte liquid inside; wherein the negative electrode is formed by binding a negative electrode active substance, which comprises metal (a) that can be alloyed with lithium, metal oxide (b) that can absorb and desorb lithium ion, and carbon material (c) that can absorb and desorb lithium ion, to a negative electrode collector with at least one selected from polyimides and a polyamide-imides; and wherein the electrolyte liquid comprises a compound represented by any one of predetermined formulae.
