Ion-Regulating SPEEK-BNNS Hybrid Interfaces Enabling Low-Barrier Zn-Ion Transport and Dendrite-Free Zinc Anodes. [PDF]

Small
A scalable organic–inorganic hybrid protective layer composed of sulfonated poly(ether ether ketone) and boron nitride nanosheets is introduced to stabilize Zn‐metal anodes. The hybrid architecture regulates Zn2+ transport, suppresses dendrite growth, and mitigates parasitic reactions, enabling uniform Zn deposition and long‐term stable cycling in ...

Photocurable electrolyte based on sulfonated poly(ether ether ketone) [PDF]

Solid State Ionics, 2011
Abstract Photocurable electrolytes were prepared by mixing proton-conductive polymer sulfonated poly(ether ether ketone) (SPEEK), cross-linking monomer divinyl sulfone (DVS), photoinitiator phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide (PI), dimethylacetamide (DMA), and ethanol. To investigate the proton transport property, a series of photocurable
