Superior High-Rate Ni-Rich Lithium Batteries Based on Fast Ion-Desolvation and Stable Solid-Electrolyte Interphase.

ABSTRACT: The fast charging-discharging performance of power batteries has very practical significance. In terms of electrochemistry, this requires fast and stable kinetics for electrochemical reaction processes. Despite the great complexity of kinetics, it is clear that lithium-ion desolvation and a subsequent step of crossing through cathode-electrolyte interphase (CEI) are crucial to high-rate performance, in which the two key steps depend heavily on the working electrolyte formula. In this work, a customized electrolyte is developed to coordinate ion desolvation and interphase formation by introducing vinylene carbonate (VC), triphenylboroxin (TPBX), and fluoroethylene carbonate (FEC) but excluding ethylene carbonate (EC). Serving Ni-rich cathodes, the customized electrolyte generates a double-l
