In this chapter, the advances and role of electrode materials for the improved performance of the batteries and application of nanomaterials for attaining better capacity and long cycle life of rechargeable batteries have been discussed. The use of fossil fuel and environmental degradation are critical issues worldwide as of today.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Electrode final properties depend on processing steps including mixing, casting, spreading, and solvent evaporation conditions. The effect of these steps on the final properties of battery electrodes are presented. Recent developments in electrode preparation are summarized.
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
