Abstract:
A lithium secondary battery includes: a positive electrode that contains a positive electrode active material; a negative electrode; and a nonaqueous electrolyte. The positive electrode active material is amorphous and is expressed by LixA[PaM1-a]yOz where, in the formula, A is Mn or Ni; M is a glass former element having an electronegativity lower than P; and x, y, a and z respectively satisfy 1
