Electrochemical and microstructural analysis of LiNi 1/3 Mn 1/3 Co 1/3 O 2 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.
