摘要
Abstract
With the popularization of electric vehicles and the gradual increase in ownership,the mar-ket demand for fast-charging batteries is becoming more urgent.In recent years,the technical devel-opment of fast-charging lithium-ion batteries is very significant.The charging rate has gradually transitioned from 2 C to 4 C,and developed towards 6 C or even 8 C.In order to address the chal-lenges brought by super-fast charging,the role and improvement directions of electrolyte in fast-charging batteries were analyzed,focusing on three aspects:solvents,electrolytes and additives.The wettability issue of the electrolyte to electrode sheets during fast charging was analyzed.The potential of the secondary injection process in reducing impedance and improving battery cycle performance was explored.It can help the academic community and industry understand the impacts of electro-lytes in fast charging,laying a foundation for the design and process optimization of electrolytes.关键词
