A high performance cathode of porous Li1.2Mn0.534Ni0.133Co0.133O2 for lithium ion batteries synthesized by a GNL-template.

The Li-rich layered cathode material Li 1.165 Mn 0.501 Ni 0.167 Co 0.167 O 2 with porous structure has been successfully synthesized through a facile co-precipitation approach followed with a high-temperature calcination treatment, adopting polymer microsphere (PSA) as a template and conductive agent. The PSA-assisted Li 1.165 Mn 0.501 Ni 0.167 Co 0.167 O 2 composite exhibits remarkably improved cycling stability and rate capability compared with the bare composite. It delivers a high initial discharge capacity of 267.0 mA h g-1 at 0.1 C (1 C = 250 mA g-1) between 2.0 V and 4.65 V. A
