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.
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).
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.
Typical Examples of Battery Electrode Materials Based on Ion Doping (A) Schematics of the crystal structure of Na 0.44 [Mn 0.44 Ti 0.56]O 2 along zone axis. (B) HAADF-STEM image of the as-prepared Na 0.44 [Mn 0.44 Ti 0.56]O 2 material along zone axis. Scale bar, 1 nm.
According to the reaction mechanisms of electrode materials, the materials can be divided into three types: insertion-, conversion-, and alloying-type materials (Figure 1 B). 25 The voltages and capacities of representative LIB and SIB electrode materials are summarized in Figures 1 C and 1D.
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
