چکیده
Ni-rich LiNi0.6Co0.2Mn0.2O2 (NCM) and LiNbO3-protected thin-film cathodes have been prepared by radio frequency (RF) magnetron sputtering. Electrochemical investigations show enhanced stability of compared with bare LiNi0.6Co0.2Mn0.2O2. The interfacial interaction LiNbO3 layers has investigated XPS depth profiling demonstrated different cathode electrolyte interface (CEI) film formation processes at the electrodes. results elaborate on between LiNi0.6Co0.2Mn0.2O2, emphasizing role layer in improving cycling performance cathodes.

Anion-redox nanolithia cathodes for Li-ion batteries
The development of lithium–air batteries is plagued by a high potential gap (>1.2V) between charge and discharge, and poor cyclability due to the drastic phase change of O2 (gas) and O (condensed phase) at the cathode during battery operations. Here we report a cathode consisting of nanoscale amorphous lithia (nanolithia) confined in a cobalt oxide, enabling charge/discharge between solid Li2O/...

متن کاملHigh‐Performance Heterostructured Cathodes for Lithium‐Ion Batteries with a Ni‐Rich Layered Oxide Core and a Li‐Rich Layered Oxide Shell
The Ni-rich layered oxides with a Ni content of >0.5 are drawing much attention recently to increase the energy density of lithium-ion batteries. However, the Ni-rich layered oxides suffer from aggressive reaction of the cathode surface with the organic electrolyte at the higher operating voltages, resulting in consequent impedance rise and capacity fade. To overcome this difficulty, we present...
