Improved interfacial resistance and crystal-structure stability in a low-cobalt P2-type sodium-ion battery cathode material

William Rexhausen, Christian Parsons, Uma Garg +2

We describe Na0.67Mn0.625Fe0.25Co0.125O2 (NMFCO), a P2-type sodium-ion battery cathode. Our composition, with significantly less Co than in an earlier study, shows discharge capaci…
