Synergistic regulation of Li deposition on F-doped hollow carbon spheres toward dendrite-free lithium metal anodes.

The notorious issues of lithium (Li) dendrite growth and volume change hinder the practical applications of Li metal anodes. LiF as a key component of the solid electrolyte interface (SEI) governs Li transport and deposition, yet the formation of LiF consumes the anions (PF/TFSI) in the electrolyte, preventing the stable cycling of Li anodes. Herein, fluorine (F)-doped hollow carbon (FHC) was synthesized and used to construct a composite current collector with FHC as an F-rich buffer layer for modifying the Cu foil.

Lithium Vanadium Oxide/Graphene Composite as a Promising Anode for Lithium-Ion Batteries.

Lithium vanadium oxide (LiVO, LVO) is a promising anode material for lithium-ion batteries (LIBs) due to its high theoretical capacity (394 mAh g) and safe working potential (0.5-1.0 V vs.

Microsized Porous SiO@C Composites Synthesized through Aluminothermic Reduction from Rice Husks and Used as Anode for Lithium-Ion Batteries.

Microsized porous SiO@C composites used as anode for lithium-ion batteries (LIBs) are synthesized from rice husks (RHs) through low-temperature (700 °C) aluminothermic reduction. The resulting SiO@C composite shows mesoporous irregular particle morphology with a high specific surface area of 597.06 m/g under the optimized reduction time.
