We are excited to share updates on two recent publications in Nature Energy and Nature Communications from Dr. Yijin Liu and his group, highlighting breakthroughs in battery material synthesis aimed at improving cathode performance, durability, and manufacturability.
In Nature Energy, researchers developed an innovative fast temperature-ramping strategy that shifts conventional solid–solid reactions to a solid–liquid pathway, producing Ni-rich cathode materials with greater compositional and structural uniformity. The approach enables negligible degradation in undoped and uncoated cathodes, offering a promising route for longer-lasting battery materials.
Complementing this work, the Nature Communications paper uses in situ inspection during sintering to reveal the dynamic processes governing the formation of single-crystalline layered oxide positive electrodes. The study shows how trace sintering aids can dramatically alter growth pathways, producing single-crystal cathode particles with significantly improved electrochemical performance.
