| Abstract: | The development of high-performance and stable solid-state lithium batteries (SSBs) is critical for advancing next-generation energy storage technologies. This study investigates LATP (Li1.3Al0.3Ti1.7(PO4)3) coatings to enhance the electrochemical performance and interface stability of NCMA83 (LiNi0.83Co0.06Mn0.06Al0.05O2) cathodes. Compared to conventional combinations with LPSC (Li6PS5Cl) solid electrolytes, LATP coatings significantly reduce interfacial reactivity and improve cycling stability. Structural and morphological analyses reveal that LATP coatings maintain the crystallinity of NCMA83 while fine-tuning its lattice stress. Electrochemical testing demonstrates that LATP-modified samples (83L5) achieve superior capacity retention (65 mAh/g after 50 cycles) and reduced impedance (Rct ~200 Ω), compared to unmodified samples (83L0). These results highlight LATP's potential as a surface engineering solution to mitigate degradation effects, enhance ionic conductivity, and extend the lifespan of high-capacity SSBs.
