摘要

Layered LiCrO2@C is a promising yet underexplored cathode for lithium-ion batteries. A rapid precipitation method enabled its synthesis within 10 min using lithium carbonate and chromium(III) nitrate, followed by carbon coating, significantly reducing time and energy compared to conventional solid-state routes (> 24 h). The LiCrO2@C composite delivers an initial discharge capacity of ~ 190 mAh g−1 at 0.05 C, attributed to the Cr3+/Cr6+ redox activity and improved conductivity. However, capacity decreases to ~ 145 mAh g−1 by the third cycle due to irreversible processes. Despite this, performance exceeds previous reports, highlighting its potential as an efficient cathode material.
