SECONDARY BATTERY

摘要

Providing a secondary battery maintaining the cyclability at room temperature and additionally being able to inhibit the cyclability from declining when being employed at high temperature.;A secondary battery includes a positive electrode including a positive-electrode active material, a negative-electrode including a negative-electrode active material, and an electrolytic solution, wherein the positive electrode and/or the negative electrode includes a binding agent containing an organic/inorganic hybrid material having an organic segment including a resin, and an inorganic segment including silica, the organic/inorganic hybrid material binding the positive-electrode active material and/or the negative-electrode active material, and the electrolytic solution includes a fluorine-containing cyclic carbonate containing at least one fluorine atom.
