After an introduction to lithium insertion compounds and the principles of Li-ion cells, we present a comparative study of the physical and electrochemical properties of positive electrodes used in lithium-ion batteries (LIBs).
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.
The cathode materials of lithium batteries have a strong oxidative power in the charged state as expected from their electrode potential. Then, charged cathode materials may be able to cause the oxidation of solvent or self-decomposition with the oxygen evolution. Finally, these properties highly relate to the battery safety.
This paper deals with the advantages and disadvantages of the positive electrodes materials used in Li-ion batteries: layered LiCoO 2 (LCO), LiNi y Mn y Co 1−2y O 2 (NMC), spinel LiMn 2 O 4 (LMO), LiMn 1.5 Ni 0.5 O 4 (LMN) and olivine LiFePO 4 (LFP) materials.
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.
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.
