Structural changes of manganese spinel at elevated temperatures
A chemical synthesis route to Cr-doped and undoped Mn spinet was developed for the purpose of detailed structural analysis for elucidating the relationship between storage performance and structural changes at elevated temperatures. We identified a two-phase segregation in the lithium compositional range of 0.6
