we designed electrolytes with weak cation solvation and strong anion solvation，该电解质使厚电极高能量密度电池在13分钟内实现80%充电量，该现象由阳离子诱导的电渗拖曳效应驱动， Xilin Chen， Daniel S. Hussey，2025年11月13日出版的《科学》杂志发表了这项成果，传统优化策略侧重于通过电极结构改性来缩短锂离子传输路径， we demonstrate that thick-electrode fast charging is constrained by solvent withdrawal within porous electrodes and the resulting electro-osmotic drag polarization，他们设计了具有弱阳离子溶剂化和强阴离子溶剂化特性的电解质体系：其中双氟化溶剂削弱锂离子溶剂化作用， David Jacobson，厚电极快充性能受限于多孔电极内部的溶剂迁出行为及其引发的电渗拖曳极化现象， 实现快充（充电速率大于4C）对于电动汽车搭载的高能量密度锂离子电池至关重要， which often compromises energy densities. In this work。

但由于对快充限制因素的认知不足。

where a difluorinated solvent weakens lithium-cation solvation and its difluoromethyl hydrogen atoms enhance anion solvation through hydrogen bonding. This electrolyte enables thick-electrode，美国马里兰大学王春生团队报道了减少电渗透阻力的电解质改善了锂离子电池的快速充电， Fu Chen， Gabriel M.
