In this plot the dots represent data from real cell datasheets. The main chemistries are: In a rechargeable lithium ion battery lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. Current production cells have an energy density ~280Wh/kg.
As important electrochemical energy storage devices, rechargeable batteries operate via redox reactions in electrode materials. Research into battery technologies has focused on higher energy densities to increase the market demand for electric-powered vehicles with good mileage.
Here, in practice, the electrode materials can be cathodes or anodes. The energy density and power density of a battery are two parameters essential to evaluating its practical performance, and they are commonly presented in Ragone plots .
Several selection criteria of electrode materials for lithium-ion batteries are proposed, including societal, economical, and technical considerations. These include their natural abundance; lack of competition with other industrial applications; eco-friendly nature for processing, usage and recycle; and low cost.
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.
At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles. Therefore, the inherent particle properties of electrode materials play the decisive roles in influencing the electrochemical performance of batteries.
