The lithium ion batteries have been a dominant power source for a wide range of portable electronic devices such as mobile phones, laptops and power tools since SONY commercialized the first lithium ion battery in 1991.

The development for higher capacity electrode material has been becoming more crucial due to expansion of lithium ion battery applications for advanced energy storage. The lithium and manganese rich cathode materials are one of the most investigated cathode materials among a variety of novel electrode materials with decent capacity. The lithium and manganese rich cathode oxides are considered as the solid solutions or nanocomposites between layered monoclinic Li₂MnO₃ and layered rhombohedral LiMO₂ (M = Ni, Co, Mn, etc.). The complex 'layered-layered' structure has inherent shortcomings which include; large initial irreversible charge capacity, poor rate performance, capacity fade and voltage decay capacity fade upon prolonged cycling.

Many efforts have been devoted to overcome these drawbacks, such as fabrication of nano-sized materials, optimized preparation methods, crystal-plane tuning, doping and surface modification. Nonetheless, the development of this type composite cathode material for lithium ion battery is still the challenge for meeting future energy storage requirements.

Herein, the investigation on the performance of the lithium and manganese rich cathode using polyacrylic acid as binder is reported. The electrode using polyacrylic acid binder shows an enhanced performance compared to that of poly(vinylidene difluoride) based electrode.
