This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
A great volume of research in Li-ion batteries has thus far been in electrode materials. Electrodes with higher rate capability, higher charge capacity, and (for cathodes) sufficiently high voltage can improve the energy and power densities of Li batteries and make them smaller and cheaper.
This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity. Many of the newly reported electrode materials have been found to deliver a better performance, which has been analyzed by many parameters such as cyclic stability, specific capacity, specific energy and charge/discharge rate.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
