Chemists pin down the cause for energy losses in high-capacity lithium-ion battery cathodes

"Li-rich complex oxides of transition metals hold record specific capacity... cations transition metals (nickel and cobalt) and oxygen anions redox reactions... voltage hysteresis—the difference in charge and discharge voltages—leads to energy losses during battery operation and limits practical applications... cathode material to remain electrically neutral, release or take in same number of electrons... kinetic hindrances and energy barriers caused by electron transfer not migration lithium cations"
