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.
