Confinement‐Engineered Thermally Programmed Ion‐Gating Separator for Decoupling Thermal–Electrochemical Feedback in High‐Energy Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A new phase‐change material encapsulated membrane offers more thermal resilience stability and safety than the conventional separators for batteries. ABSTRACT Thermal runaway in lithium‐ion batteries arises from the intrinsic coupling between heat generation and ion transport, yet conventional shutdown separators primarily rely on passive pore collapse

Controlling electric potential to inhibit solid-electrolyte interphase formation on nanowire anodes for ultrafast lithium-ion batteries

Nature Communications, 2018
Lithium-based rechargeable batteries suffer from unstable evolution of solid-electrolyte interphase on the electrode surface. Here, the authors provide an approach to inhibiting SEI formation by controlling electric potential distribution across ...

Freeze‐Thaw Engineered Dual Conductivity Polymeric Binder Stabilizes Large‐Volume‐Change Lithium–Ion Battery Anodes

Advanced Functional Materials, EarlyView.
This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

The Role of Phosphorous in the Solid Electrolyte Interphase of Argyrodite Solid Electrolytes

The solid electrolyte interphase that forms on Li6PS5Cl argyrodite solid electrolytes has been reported to continually grow through a diffusion-controlled process, yet this process is not fully understood. Here, we use a combination of electrochemical and X-ray photoelectron spectroscopy techniques to elucidate the role of phosphorus in this growth ...

Completing the Picture of the Solid Electrolyte Interphase [PDF]

Joule, 2019
Although solid electrolyte interphase (SEI) formation is an important factor in battery performance, difficulties in characterizing the SEI mean that it is still not well understood. In this issue of Joule, Nanda and coworkers utilize tip-enhanced Raman spectroscopy to paint a more complete picture of the SEI on silicon electrodes.

DNP-enhanced NMR of Lithium Dendrites: Selective Observation of the Solid–Electrolyte Interphase [PDF]

, 2019
Li metal anodes represent the ultimate energy density, but to address safety issues caused by dendrite formation, it is critical to understand the solid–electrolyte interphase (SEI) layer which forms on the metal surface.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

Advanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Reconstructing Residual‐Solvent‐Involved Li+ Coordination in PVDF‐HFP Polymer Electrolytes for Stable Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
2,2,2‐trifluoroethanamide‐mediated coordination regulation reconstructs the local Li+ environment in PVDF‐HFP polymer electrolytes by weakening residual DMF‐dominated coordination and promoting TFSI−‐involved anion‐rich solvation. This strategy facilitates Li+ migration and interfacial desolvation, promotes the formation of a thin inorganic‐rich SEI ...
