Abstract

A positive electrode material for a secondary battery, wherein the positive electrode material includes a triclinic crystal structure.

Claims (4)

1. A positive electrode material for a secondary battery,

wherein the positive electrode material includes a triclinic crystal structure and is represented by Li 4+x (Fe 1−z N 2 ) 4−0.5x (P 2 O 7 ) 3 , where −0.65≤x≤0.75, 0.0<z≤0.7.

2. A positive electrode material for a second battery,

wherein the positive electrode material includes a triclinic crystal structure and is represented by Li 4+x (Fe 2 Mn z ) 4−0.5x (P 2 O 7 ) 3 , where −0.65≤x≤0.75, 0.0<z≤0.7.
