摘要

Developing new electrolytes that cater to the needs of lithium anode and Ni-rich cathodes is critical for next-generation battery technologies with high energy density and enhanced safety. Although significant advances have been made in non-aqueous electrolytes with wide electrochemical stability window (ESW), the performance of lithium battery is still not comparable to that of commercial Li-ion batteries (LIBs) due to the notorious reactivity of metallic lithium as well as the catalytic nature of high-voltage cathode. Such situations require rational design of advanced electrolytes and mechanistic understanding on interphase formation for stabilizing the electrolyte-electrode interfaces and supporting the next-generation battery chemistries beyond LIB technology.
