A new amphiphilic solvent is rationally designed to induce self-assembly of the electrolyte solution to form a peculiar core-shell-solvation structure. Such unique solvation structure bestows improved ionic conductivity, low desolvation energy, and highly robust and conductive SEI, which overcomes the long-standing Li compatibility and deposition kinetic challenges, enabling the stable operation of
合理设计一种新型两亲溶剂,诱导电解质溶液自组装形成独特的核-壳-溶剂化结构。这种独特的溶剂化结构赋予了改善的离子电导率、低去溶剂化能量以及高度稳健和导电的SEI,克服了长期存在的锂相容性和沉积动力学挑战,使锂金属电池能够在超低温下稳定运行。
