Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

open access: yesAdvanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Operando monitoring the lithium spatial distribution of lithium metal anodes [PDF]

open access: yesNature Communications, 2018
AbstractElectrical mobility demands an increase of battery energy density beyond current lithium-ion technology. A crucial bottleneck is the development of safe and reversible lithium-metal anodes, which is challenged by short circuits caused by lithium-metal dendrites and a short cycle life owing to the reactivity with electrolytes.

Unlocking Ultra‐Long Cycle Stability of Li Metal Electrode by Separators Modified by Porous Red Phosphorus Nanosheets

open access: yesAdvanced Functional Materials, EarlyView.
Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

Multi‐Faceted Binder Enhancement via Slurry‐Applicable Thiol‐Ene Click Chemistry for Low‐Pressure‐Operable All‐Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Cross‐linked binders with enhanced resiliencies under low operating pressures are designed via in situ thiol‐ene click reactions within slurries. Cross‐linking improves the Young's moduli and elasticities of the styrene‐butadiene rubber binders, effectively mitigating interparticle delamination within the composite cathodes induced by volumetric ...
