- •
SIMS is applied to the assessment of coating materials on positive electrodes in LIB.
- •
6Li-enriched LCO modified with 6Li-enriched LWOs are developed.
- •
Contribution of Li-ion diffusibility of LWOs to interfacial resistance is investigated.
- •
Amorphous state LWO shows smooth Li-ion diffusion between the LWO and LCO layers.
- •
Fast Li-ion self-diffusibility into LWO contributes to decreasing interfacial resistance.
