We have published a research paper in ACS Applied Energy Materials. We report a room-temperature coating method based on the molecular self-assembly of metal precursors guided by the high density of OH groups on a thin, surface-adherent polydopamine (PDA) film deposited on LLO particles. In particular, a nanoscale Zr(OH)4 surface coating significantly improved the cycle performance of a high-capacity LLO cathode (∼300 mAh g–1), which retained more than 82.3% of the initial capacity after 150 charge–discharge cycles (vs 53.7% for the bare LLO). Congrats to Mr. Yong Wang and Zhaoshun Wang and all the co-authors.
