锂离子电池极片干燥研究进展
Research progress on drying of lithium-ion battery electrodes
摘要
Abstract
The moisture content of solvents is a key factor affecting the safety of Li-ion batteries.The residual solvents and impurities in the pores of Li-ion battery materials can react with the electrolyte of the battery,causing changes in electrolyte composition,affecting battery performance.At the same time,it increases the internal resistance of the electrodes,reduces the cycle life,and poses a safety hazard.The drying process is crucial for controlling the solvent content and affecting the crystal structure of the finished product,and the selection of drying parameters is directly related to product quality.This review explored the basic principles and influencing factors of common drying tech-niques,discussed the heat and mass transfer laws represented by the solvent moisture migration pro-cess in the drying of Li-ion battery electrode sheets,and introduced traditional continuous medium models and emerging 3D drying models.Also,this paper analyzed the influence of typical drying pro-cess parameters and material properties on the drying characteristics and quality of lithium batter-ies,and envisaged the future of Li-ion battery drying technology in order to provide theoretical basis and technical support for improving the quality,reducing consumption,and automatic control of lithium battery electrode drying processes.关键词
