Abstract
Electrolyte with weak solvation structure has been designed by introducing isoxazole. Weak Li + -solvent interaction and fast de-solvation is benefited to form stable SEI and uniform Li deposition, allowing the cell to achieve high capacity of 118.4 mA h g −1 and stable cyclability at −40 °C and 2C.
