A lithium secondary battery is disclosed which includes: a cathode that is capable of storing/releasing a lithium ion, an anode that is capable of storing/releasing a lithium ion, a separator that separates the electrodes from each other, and an electrolyte solution. The cathode includes a cathode-active material and an electroconductive material comprised of at least one gas-generating resin that is decomposed with generation of a gas at a temperature at which oxygen is eliminated from the cathode-active material, and an electroconductive filler. |
