Recent progresses in advanced electrode materials, separators and electrolytes for lithium-ion batteries

Abstract

Lithium-ion batteries (LIBs) possess several advantages over other types of viable practical batteries, including higher operating voltages, higher energy densities, longer cycle lives, lower rates of self-discharge and less environmental pollution. Therefore, LIBs have been widely and successfully applied in portable electronic devices and industrial fields. However, the rapidly increasing demands of new energy vehicles have also rapidly increased the performance requirements of LIBs, including the need for higher power densities, greater capacity densities and better safety. As battery designs gradually standardize, improvements in LIBs performances mainly depend on the technical progresses in key electrode materials such as positive and negative electrode materials, separators and electrolytes. In order for LIBs performances to meet the rising requirements, many studies on structural characteristics and morphology modifications of electrode/separator/electrolyte materials with different synthesis methods have been conducted. In this review, recent progresses of LIBs are reviewed with a focus on positive electrode materials, negative electrode materials, separators and electrolytes in terms of energy density, power density, life-cycle and safety. To accelerate the research and development as well as to overcome the challenges of LIBs technology and application, several possible research directions are also discussed to further improve LIBs performances.
