Graphene-Based Metal-Ion Batteries

Graphene-based metal-ion batteries are a promising technology for energy storage due to the unique properties of graphene, such as its high surface area, good electrical conductivity, and mechanical strength. These batteries utilize graphene as a conductive additive or electrode material, which enhances their performance, energy density, and cycling stability. The metal ions used in these batteries can be lithium (Li), sodium (Na), potassium (K), or other multivalent ions (e.g., magnesium (Mg), zinc (Zn), aluminum (Al)), which are inserted and extracted from the graphene electrode during charging and discharging cycles. Graphene-based metal-ion batteries have shown excellent electrochemical performance, including high capacity, fast charge–discharge rates, and long cycle life. Furthermore, they have the potential for large-scale commercial applications due to their low cost, safety, and environmental friendliness. Despite the encouraging results, additional research is required to optimize the design and performance of graphene-based metal-ion batteries for energy storage applications. This chapter details the preparation, and characterization of graphene and its application for metal ion batteries.
