Research progress on mechanism of lithium dendrite growth and inhibition strategies
The irregular growth of dendritic lithium in lithium batteries limits their electrochemical performance,shortens their lifespan,and reduces their safety,becoming a significant obstacle to the development of lithium battery technology.This article summarizes the growth mechanism and inhibition strategies of lithium dendrites,including four models of lithium dendrite growth:surface nucleation and diffusion model,heterogeneous nucleation model,space charge model,and solid electrolyte interphase(SEI)model.Based on the growth models of lithium dendrites,this article categorizes and explains the recent inhibition strategies,including membrane modification,electrode design,and electrolyte improvement.The research results indicate that the development of Janus membranes and membrane coating materials is the most promising membrane modification method.Improving the lithium metal anode through methods such as applying a magnetic field and coating layers is an effective electrode design strategy.Gel electrolytes are one of the future trends in electrolyte improvement.The study of lithium dendrite inhibition strategies provides direction for the development of high-performance lithium batteries.
