Electron beam-assisted synthesis and modification of electrode/separator materials for lithium-ion batteries: Progress and prospects

Lithium ion batteries (LIBs) have been recognized as an indispensable option for substantially reducing fossil fuel consumption in industrial production and daily life. Given that the electrode and separator are pivotal components of LIBs, their properties notably impact the electrochemical performance of the entire system. Consequently, the efficient synthesis and modification of electrode or separator using versatile and cost-effective methods are the key for a wide range of LIBs applications. Currently, electron beam technology has emerged as a potent choice for synthesizing and modifying electrode and separator materials. Herein, we categorize electron beam technology and outline its vital roles in material processing. Additionally, the advancements on the synthesis and modification of anode, cathode as well as separator materials with the assistance of electron beam is highlighted, and the mechanisms of electron beam to enhance the electrochemical properties for electrode/separator are negotiated. Finally, we examine the challenges and prospects associated with the application of electron beam technology in the context of LIBs.
