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).
Some important design principles for electrode materials are considered to be able to efficiently improve the battery performance. Host chemistry strongly depends on the composition and structure of the electrode materials, thus influencing the corresponding chemical reactions.
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.
Clearly, the electrochemical properties of these electrode materials (e.g., voltage, capacity, rate performance, cycling stability, etc.) are strongly dependent on the correlation between the host chemistry and structure, the ion diffusion mechanisms, and phase transformations.23
Electrode materials include three different classes of lattices according to the dimensionality of the Li + ion motion in them: olivine, layered transition-metal oxides and spinel frameworks. Their advantages and disadvantages are compared with emphasis on synthesis difficulties, electrochemical stability, faradaic performance and security issues.
In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
