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.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
Lithium layered cathode materials, such as LCO, LMO, LFP, NCA, and NMC, find application in Li-ion batteries. Among these, LCO, LMO, and LFP are the most widely employed cathode materials, along with various other lithium-layered metal oxides (Heidari and Mahdavi, 2019, Zhang et al., 2014).
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
Cathode materials determine significantly not only the performance of lithium-ion batteries but also their calendar and cycle lives.
