摘要
The solvothermal method was used to prepare 0.125 mol % Li3BO3-coated graphite powder as an anode mate-rial for an all-solid-state lithium battery. Scanning electron microscopy observations and electron probe microanalysis revealed the Li3BO3 was distributed uniformly on the graphite surface as fine particles and a film. The average crush strength of the coated graphite powder particles was higher than that of the uncoated graphite powder particles, and the standard deviation was lower. An all-solid-state lithium battery with the coated graphite powder showed a slightly higher capacity retention rate than that containing uncoated graphite powder.
