Summary: In this work, localized high concentration electrolytes (LHCEs) based on tetramethylene sulfone (TMS) were designed. TMS-based LHCEs can achieve excellent compatibility with high energy density lithium-ion batteries (LIBs) when combined with a proper additive. The unique solvation structure of LHCEs facilitates the formation of highly effective solid electrolyte interphase (SEI) and suppresses the degradation of positive electrode materials in LIBs. The superior interphasial properties of LHCEs are the key to realizing the long lifespan of high energy density LIBs.

Summary: In this study, Ni-rich LiNi0.8Mn0.1Co0.1O2 or NMC811 cathode material was coated with crystalline ZrO2 nanoparticles using a green and scalable mechanofusion technique with an annealing process. The controllable synergistic effect of ZrO2 coating and Zr4+ doping was investigated, and it was found that the mechanofusion with post-annealing at 800 degrees C could fine-tune the shell thickness and doping gradient. The optimized NMC@Zr-800 material showed excellent capacity retention over 1000 cycles at a severe state-of-charge, attributed to the surface protection by the ZrO2 coating and Zr4+ doping.

Summary: The spontaneous formation of solid electrolyte interphase (s-SEI) on the surface of lithium metal was reported in this study. Differences in the properties of the s-SEI layers formed in different electrolytes were investigated, showing that the composition mainly consisted of LiF, Li3N, ROCO2Li, and ROLi. Thicker s-SEI layers were found to increase the polarization potential of plating/stripping, while Li3N-riched s-SEI reduced the polarization potential.
