Sulfide all-solid-state lithium battery (ASSLB) with nickel-rich layered oxide as the cathode is promising for next-generation energy storage system. However, the Li transport dynamic and stability in ASSLB are hindered by the structural mismatches and the instabilities especially at the oxide cathode/sulfide solid electrolyte (SE) interface. In this work, we have demonstrated a simple and highly effective solid-state mechanofusion method (1500 rpm for 10 min) to combine lithium conductive NASICON-type LiZr(PO) nanocrystals (∼20 nm) uniformly and compactly onto the surface of the single crystallized LiNiCoMnO, which can also attractively achieve Zr doping in NCM811 and oxygen vacancies in the LZPO coating without solvent and annealing.

Ti₃SiC₂/Carbon nanofiber composites with one-dimensional nanostructures were successfully synthesized via electrospinning. Systematic electrochemical tests showed that the Ti₃SiC₂/Carbon composite possesses a large specific capacitance of 133.
