Researchers at the Institute of Metal Research, Chinese Academy of Sciences and the Shenyang National Center for Materials Science led by Wang Chunyang used atomic-scale super-resolution imaging to reveal, for the first time, the atomic origins of failure in LiCoO2 cathodes operating at ultrahigh voltages. The study, titled Atomic origins of ultrahigh-voltage failure in LiCoO2 cathodes, was published in the Journal of the American Chemical Society after nearly two years of work and is presented by the authors as a major advance in understanding battery-material failure under extreme conditions.
