SDD
Fe doped LiNi0.5Mn1.5O4 was taken as a model in the PCCP paper. Efforts in
enhancing the sensitivity for detecting light elements will enable new insights on
electrode interface manipulation and engineering toward better energy storage
system. This technique will find applications in other areas such as mining and health.
