The isocyanate-incorporated elastomeric electrolytes formed through polymerization-induced phase separation exhibit high ionic conductivity, mechanical elasticity, and robust interphases, enabling stable Li metal batteries cycling at a high cut-off voltage of 4.7 V vs. Li/Li+. Abstract To facilitate the use of solid polymer electrolytes (SPEs)...

Branched phosphorus (P)-doped ruthenium dioxide (RuO2) nanofibers are constructed to manipulate the d-band center of ruthenium sites and optimize the adsorption/desorption energy of reaction intermediates during hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) processes. Thus the obtained P-doped RuO2 nanofibers present outstanding...

A hollow carbon framework is used as a microreactor for inverse vulcanization between 1,3-diisopropylbenzene and sulfur. This dual confinement strategy enhances Li–S coin cells’ cycling stability and capacity retention. (Poly)sulfide distribution is visualized by Energy selective Backscattered electron imaging (EsB), unraveling the sulfur lithiation...

This work presents an approach to optimize anion exchange membrane fuel cell performance via fine-tuning of ionomer ion exchange capacity. An optimal design choice for anode and cathode is based on a systematic investigation of correlations between physio-chemical characteristics of ionomers and phenomena impacting fuel cell operations and supported...

Sn-friendly hole transport material (HTM) for the n-i-p tin-reach, lead-tin halide perovskite solar cells (LTH-PSCs) is developed by mixing Spiro-OMeTAD with 4-Isopropyl-4'-methyldiphenyliodonium tetrakis(pentafluorophenyl)borate (dpi-TPFB) as a dopant and blended with P3HT. Within this blended HTM, hydrophobic P3HT predominantly resides on the surface...

Theorizing a generalized mechanism for additive engineering in precursor ink by unraveling the role of CsCl in gas-quenching-assisted printing of FAPbI3 films for high-performance, fully printed perovskite photovoltaics: Cesium is indispensable for triggering stable α-FAPbI3 nucleation and templating the growth of a highly crystalline α-FAPbI3 film,...
