Promising theoretical capacities and high voltages are offered by Li-rich disordered rocksalt oxyfluoride materials as cathodes in lithium-ion batteries. However, as has been discovered for many other Li-rich materials, the oxyfluorides suffer from e

Many of the challenges faced in the development of lithium-ion batteries (LIBs) and next-generation technologies stem from the (electro)chemical interactions between the electrolyte and electrodes during operation. It is at the electrode-electrolyte

Lithium-rich transition metal disordered rock salt (DRS) oxyfluorides have the potential to lessen one large bottleneck for lithium ion batteries by improving the cathode capacity. However, irreversible reactions at the electrode/electrolyte interfac

Publikováno v: ECS Meeting Abstracts. :167-167

Liquid solid interfaces in batteries are not trivial to study in a realistic and detailed way. Often interfaces of cathodes or anodes in cycled batteries, are studied post mortem and at ultra-high vacuum to really determine the chemical composition i
