Abstract
The present invention relates to a lithium secondary battery provided with a positive electrode having vanadium peroxide as an active material, a negative electrode having niobium pentoxide doped with lithium as an active material, and an electrolyte of an organic solvent in which a lithium salt is dissolved. A corrosion-resistant metal powder is used as a conductive material in the negative electrode. In addition, a corrosion-resistant metal may be used as a current collector of the negative electrode. This battery is excellent in charging and discharging cycle characteristics and storage life, is superior in moldability of the negative electrode composition and can be mass-produced.
