ABSTRACT Due to the strong affinity between solvent and Li + , desolvation process of at interface as a rate‐controlling step slows down, which greatly reduces low‐temperature electrochemical performance lithium‐ion batteries (LIBs) thus limits its wide application in energy storage. Herein, improve tolerance, localized high‐concentration electrolyte based on weak solvation (Wb‐LHCE) has been designed by adding diluent hexafluorobenzene (FB) solvating tetrahydrofuran (THF). Combining theoretical calculations with characterization tests, it is found that addition FB, dipole–dipole interaction causes FB compete for THF. This competition move away from weakening binding THF, whereas anions are transported into shell forming an anion‐rich structure. In accelerating process, this unique structure optimizes composition CEI film, making thin, dense, homogeneous, rich inorganic components, improving interfacial stability battery. As result, assembled LiFePO 4 /Li half‐cell shows excellent performances low temperature. That is, can maintain high discharge specific capacity 124.2 mAh g −1 after 100 cycles rate 0.2C −20°C. provides attractive avenue design advanced electrolytes improvement battery tolerance harsh conditions.
