Electrochemical and microstructural analysis of LiNiMnCoO cathode composites prepared using the SEED method

Cathode composites were fabricated using the nuclear growth (SEED) method. Compared to mortar mixing, the SEED method demonstrated higher cycle stability, with a 90LiNi 1/3 Mn 1/3 Co 1/3 O 2 -10Li 7 P 2 S 8 I composite retaining 99.7% discharge capacity after six cycles compared to 66.1%. Cross-sectional SEM-EDX images suggest that the solid electrolyte was more uniformly distributed in the cathode composite prepared using the SEED method. This study opens up the potential for higher cathode-active material loading ratios. The all-solid-state battery with the cathode composite fabricated by the SEED method demonstrated higher cycle stability, and cross-sectional SEM-EDX images suggest that the solid electrolyte was more uniformly distributed in the cathode composite prepared using the SEED method.
