PROBLEM TO BE SOLVED: To provide a lithium-polymer secondary battery having a superior cycle characteristics, and reliability, and high energy density. SOLUTION: The lithium-polymer secondary battery consists of a lithium- contained complex nitride expressed by general formula, Li(3-x)-yMxN (where M is at least one kind of transition metals selected from among a group of Co, Mn, Ni and Cu, 0.3<=x<=0.6, 0<=y<=3-x), a positive pole comprising conductive and polymer materials, a negative pole comprising conductive and polymer materials and a polymer-gel electrolyte, containing an organic electrolytic solution. |
