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 ...

Effect of Imidazolium Concentration in Densely Functional Polymer Binder on Robust Electrochemical Kinetics and Cycling Performance of Lithium Iron Phosphate Cathode

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The improved performance of the cathodic half‐cell containing poly(oxycarbonylmethylene 1‐allyl‐3‐methylimidazolium) (PMAI) binder (PMAI/LFP) is attributed to the ion conduction properties of imidazolium‐functionalized polymer, which participates in cathode‐electrolyte interphase (CEI) formation as confirmed by X‐ray photoelectron spectroscopy and ...

Probing the Cause of Capacity Fade in Large‐Format Li‐Ion Pouch Cells through Multimodal Characterization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
A comprehensive multimodal characterization of two end‐of‐life cells from a retired Nissan Leaf battery pack, subjected to accelerated aging to mimic extended use in second‐life applications shows that electrolyte degradation and loss is a more critical contributor to cell degradation toward the knee‐point in these cells than degradation of the ...

Surface Functionalization of Si Nanoparticles by Hydrosilylation: Access to High‐Performance Si Anodes for Li‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Surface‐functionalized SiNPs are synthesized by a simple and scalable hydrosilylation method using 4‐vinylpyridine (4VP), 1‐vinyl‐2‐pyrrolidinone (1V2P), and acrylic acid (AA). The Si‐4VP‐based Li‐ion cells achieved a promising long life of 300 cycles, retaining 60% of the initial capacity (2375 mAh g−1).
