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).
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.
The most widely used positive electrode materials in current industries are lithiated iron phosphate LiFePO 4 (LFP), lithiated manganese oxide LiMn 2 O 4 (LMO), lithiated cobalt oxide LiCoO 2 (LCO), lithiated mixed oxide LiNi x Mn y Co z O 2 (NMC), such as NMC-111, NMC-523 or NMC-622, and lithiated mixed oxide LiNi a Co b Al c O 2 (NCA) .
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
To compare the properties of positive electrode materials with different Ni content, we synthesized the most popular Ni-rich positive electrode materials NMC622 (x = 0.6) as well as the higher Ni content material NMC811 (x = 0.8) and LNO (x = 1).
Coating of the electrode can enhance ionic/electronic conductivity and stability of positive electrode materials. Each coating method or material shows its own advantages, disadvantages, and different coating protocols can greatly affect the chemical or physical composition and structures of a coating on electrode materials.
