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 ...

Impedances of electrochemically impregnated nickel electrodes as functions of potential, KOH concentration, and impregnation method [PDF]

open access: yes
Impedances of fifteen electrodes form each of the four U.S. manufactures were measured at 0.200 V vs. the Hg/HgO reference electrode. This corresponds to a voltage of 1.145 for a Ni/H2 cell. Measurements were also made of a representative sample of these

Multifunctional Structural Electrolyte with Glass Fiber‐Reinforced Polyvinyl Alcohol/Epoxy Matrix with Optimized Lithium Salt and Nanofiller

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study presents a novel structural electrolyte reinforced with glass fiber and a polyvinyl alcohol/epoxy matrix incorporating optimized lithium salt and ceramic nanofiller. Its multifunctionality—mechanical, electrochemical, and thermomechanical—is evaluated using various characterization techniques.
