Activation of trace LiNO additives by BF in high-concentration electrolytes towards stable lithium metal batteries.

The activation of trace LiNO additives in high-concentration electrolytes is achieved by BF due to its Lewis acidity. This advanced electrolyte can promote the decomposition of LiNO into LiN, attaining enhanced cycle reversibility of lithium anodes, which broadens the application of LiNO additives.

Anionic Redox Regulated via Metal-Ligand Combinations in Layered Sulfides.

The increasing demand for energy storage is calling for improvements in cathode performance. In traditional layered cathodes, the higher energy of the metal 3d over the O 2p orbital results in one-band cationic redox; capacity solely from cations cannot meet the needs for higher energy density. Emerging anionic redox chemistry is promising to access higher capacity.

Graphite prelithiation by solid electrochemical corrosion of lithium metal with a superficial mosaic structure.

A transformative concept of solid electrochemical corrosion has been put forward, in which solid-state electrolyte LiPON has been applied to replace the liquid one to prelithiate graphite with Li-metal. Thus, high prelithiation efficiency and low polarization of the treated anode can be obtained, with a unique mosaic structure left at the surface.
