In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
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.
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
This review gives an account of the various emerging high-voltage positive electrode materials that have the potential to satisfy these requirements either in the short or long term, including nickel-rich layered oxides, lithium-rich layered oxides, high-voltage spinel oxides, and high-voltage polyanionic compounds.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
