Identifying the nanostructure of residual Li in high-Ni cathodes for lithium-ion batteries† With the increasing demand for higher energy density in lithium-ion batteries (LIBs), designing high-Ni cathodes with maximized Ni content is becoming essential. This pursuit leads to an increase in surface residual Li compounds (Li2CO3 and LiOH), triggering notorious issues such as severe side reactions, gas evolution, and the necessity for additional manufacturing processes.

To improve Li-ion battery performance, intermetallic anodes have been extensively researched due to their higher gravimetric and volumetric capacities. (1) Among the intermetallics, Si-based anodes can have 10 times the gravimetric capacity than the standard graphite electrode and thus represent a promising path for improving the energy density of current Li-ion batteries.
