A positive electrode (12) and a negative electrode (14) are configured through a separator (15) in between. The positive electrode (12) contains a compound expressed by a general formula Li1+xMnyFezPO4 (wherein x, y and z are values within ranges of 0<x<0.1 0.5<y<0.95, and , 0.9<y+z~ 1, respectively). According to the compound the higher discharge , voltage can be obtained due to Mn the Jahn Teller effect of Mn3+ can be attenuated and furthermore distortion of the …
