Abstract

See full text

The invention provides a positive electrode material and a battery using the same which can achieve a higher discharge voltage and which can obtain excellent charge-and-discharge properties, without reducing the capacity. 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 03+ can be attenuated and furthermore distortion of the crystal structure and the reduction of the capacity can be inhibited due to Fe and the excess Li.
