Abstract Improving the energy density of Lithium (Li)‐ion batteries (LIBs) is vital in meeting growing demand for high‐performance storage and conversion systems. Developing high‐voltage LIBs using high‐capacity cathode materials promising enhancing density. However, conventional electrolyte face serious decomposition structural degradation at high operating voltages. Herein, a dual‐salts lithium bis(fluorosulfonyl)imide bis(trifluoromethanesulfonyl)imide(LiFSI‐LiTFSI) developed to improve cycling stability cobalt oxide (LiCoO 2 , LCO)||Li batteries. Operando X‐ray diffraction analysis experiments are carried out characterize materials, suggesting severe irreversible phase transformation voltage levels. Aging simulations, combined with experimental studies, suggest that fast loss active mainly responsible capacity Carbon‐coated LCO cathodes synthesized mitigate degradation. The designed LCO||Li cells exhibit retention over 85% after 400 cycles 4 .7V. present work provides novel insight into understanding LCO‐based Li‐metal batteries, thus facilitating their practical applications.

Abstract High‐voltage LiCoO 2 (LCO) attracts great interest due to its high theoretical capacity, however, the aggravated oxygen redox, Co dissolution, and lattice degradation at voltage potentially induce instability of crystal structural cathode–electrolyte interphase, can ultimately lead severe capacity fading. Herein, a design strategy spin modulation is presented stabilize surface bulk structure commercial (C‐LCO). The prepared high‐spin state via field elevates Co─O band gap, suppresses electronic compensation voltage, reduces side reactions reactive dissolved ions with electrolyte, which greatly restrains irreversible phase transition from O3 H1‐3 degeneration interphase. As result, spin‐modulated shows significantly improved electrochemical performances including discharge stable cycling behavior, enhanced rate capability. This work based on modification by apply other layered metal oxide cathodes, providing new avenue for developing high‐energy–density cathodes.
