Li‐Ion Batteries: Cathode‐Electrolyte‐Interphase Film Formation on a LiNiO₂ Surface in Conventional Aqueous Electrolytes: Simple Method to Improve the Electrochemical Performance of LiNiO₂ Electrodes for Use in Aqueous Li‐Ion Batteries (Adv. Energy Mater. 25/2021)

In article number 2100756, Kohei Miyazaki and co-workers demonstrate that a cathode-electrolyte-interphases film can be created on a LiNiO2 electrode in conventional aqueous electrolytes (nitrates, NO3), and improve electrochemical properties, such as reversible capacities and cyclability. This study suggests that LiNiO2 has great potential for application as a cathode material for high energy-density aqueous Li-ion batteries.
