Graded Solvation‐Structure Electrolyte for Synergistic Polysulfide Confinement and Interfacial Stabilization in Potassium‐Sulfur Batteries

Carbon Energy, EarlyView.
A graded solvation structure is designed through a strongly–moderately–weakly solvating strategy to synergistically regulate potassium polysulfide dissolution and K‐anode deposition behavior. This tailored electrolyte effectively stabilizes the electrode/electrolyte interphases and accelerates sulfur redox kinetics.

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

Carbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...

ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

Carbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.
