Lithium-ion batteries have become a versatile energy storage solution for various applications, such as portable electronics and electric vehicles, due to their numerous advantages. The increasing demand for higher energy density has prompted researchers to explore innovative strategies to improve the performance of these batteries. This study systematically investigates cutting-edge techniques aimed at enhancing the energy density of lithium-ion batteries. By conducting a detailed analysis of different battery components, this study evaluates the feasibility, efficiency, and potential impact of these approaches on future battery technologies. By giving some concrete examples, such as NMA(LiNi1-x-yMnxAlyO2), LFP(LiFePO4) batteries in cathode, popular silicon-based materials in anode, novel dual conductive binder and solid electrolyte (solid electrolyte interface), some of the working principles are described and the electrochemical properties of the batteries are comparatively analysed. This research aims to provide readers with a comprehensive understanding and research direction for advancing the energy density capabilities of lithium-ion batteries.
