Abstract Solid state single‐ion conducting polymer electrolytes (SSPEs) are one of the most promising candidates for long‐life lithium‐metal batteries. However, traditional polyanion‐type structure SSPEs inevitably gives rise to insufficient conductivity and inferior mechanical stability, which limits their practical application. Herein, an interpenetrating network (PTF‐4EO) is fabricated by crosslinking lithium tetrakis(4‐(chloromethyl)‐2,3,5,6‐tetrafluorophenyl)borate salt with...

Abstract The stringent demands for lithium salts make the design of “polymer‐in‐salt” type solid electrolyte restricted since it was proposed in 1993.

Hydroxyl LiPVFM Dual‐Li forms strong hydrogen bond with carboxylic acid group generated...

Herein we propose a novel ultrathin crosslinked PDOL-based electrolyte (PTADOL), which is prepared via...

The diffusion behavior of an active Brownian particle (ABP) in polymer solutions is studied using Langevin dynamics simulations. We find that the long time coefficient $D$ can show a non-monotonic dependence on size $R$ if force $F_{a}$ large enough, wherein bigger would diffuse faster than smaller one which quite counterintuitive. By analyzing short comparison to passive one, we such non-trivial results from competition between persistence motion ABP and length-scale dependent effective...
