Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
The stability and loss rate of positive electrode materials directly affect the cycle life of lithium batteries. During the charging and discharging process, the loss of active substances in positive electrode materials and the destruction of material structure will lead to the attenuation of battery performance.
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.
At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles. Therefore, the inherent particle properties of electrode materials play the decisive roles in influencing the electrochemical performance of batteries.
The development of excellent electrode particles is of great significance in the commercialization of next-generation batteries. The ideal electrode particles should balance raw material reserves, electrochemical performance, price and environmental protection.
The ideal electrochemical performance of batteries is highly dependent on the development and modification of anode and cathode materials. At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles.
