Enhancing Ion‐Electron Transport in Positive Electrode of Solid‐State Lithium Metal Batteries With Multifunctional Catholyte Made of Polymer Mixed Ionic‐Electronic Conductor PEDOT:PSSTFSI and Li3InCl6

open access: yesAdvanced Energy Materials, EarlyView.
A mixed ion‐electron conducting polymer binder, PEDOT:PSSTFSI, enhances both ionic and electronic transport in NMC‐based positive electrode composite (PEC) for ASSBs. Optimal polymer loading (0.33 wt.% in PEC) provides the most balanced transport, with an effective conductivities (σel/σion) ratio closest to unity, enabling high discharge capacity at 1 ...

Depth‐of‐Discharge‐Dependent Chemical Evolution in Sulfurized Polyacrylonitrile Cathodes for Ether‐Based Room‐Temperature Sodium–Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Sulfurized polyacrylonitrile (SPAN) is investigated as a cathode for room‐temperature Na–S batteries in ether‐based electrolytes under controlled discharge depths. Depth‐of‐discharge‐dependent structural evolution reveals that deep discharge below 1.0 V destabilizes SPAN structure, alters polysulfide equilibria, and promotes sodium dendrite formation ...

Trinuclear Heptamethine Dyes for Shortwave Infrared In Vivo Imaging

open access: yesAngewandte Chemie, EarlyView.
The reactivity of cyclopentenyl‐bridged polymethine dyes is leveraged to synthesize shortwave infrared (SWIR)‐emissive di‐ and trinuclear polymethine dyes. Chromenylium‐ and flavylium‐based trinuclear dyes demonstrate increased nucleophilic stability, minimal aggregation in micelle formulations, and notable lymph node accumulation.

Addressing Bottlenecks to Achieve High‐Energy Sodium‐Ion Cells Using Tin Anodes

open access: yesAdvanced Energy Materials, EarlyView.
The challenges in coupling high voltage cathode with Sn‐alloying anode or in anode‐free cell, using glyme based electrolytes to realize high energy Na‐ion cells are reported. Surface protection strategy such as SnO coating on Sn or trapping the parasitic species from poisoning the anode, helps improving the cyclability, with ∼100% capacity retention ...

In Situ Measurement of Oxygen Vacancy Dynamics and Surface Exchange Reactions in Oxide Electrode under Solid Electrochemical Cell Operating Conditions

open access: yesAdvanced Energy Materials, EarlyView.
This study establishes an in situ electrochemical framework using dense bulk electrodes to identify defect chemistry and surface kinetics. While oxygen vacancy concentration is derived via bias modulation, surface exchange coefficients are quantified at open circuit voltage conditions to isolate kinetics.

Electrochemical Stabilization of Polytetrafluoroethylene (PTFE) via Electronic Band Engineering Enables Long‐Life, High‐Energy‐Density Li‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Frontier orbital energy engineering of PTFE by incorporating electron‐withdrawing oxygen‐ and nitrogen‐containing functional groups alters the local electronic environment and elevates the LUMO energy. This molecular modification strategy suppresses reduction‐induced side reactions in dry‐processed anodes.
