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 Single‐ion conductive polymer electrolytes (SICPEs) with a cationic transference number ( t Li + ) close to unity exhibit specific advantages in solid‐state batteries (SSBs), including mitigating the ion concentration gradient and derived problems, suppressing growth of lithium dendrites, improving utilization cathode materials rate performance SSBs. However, application SICPEs remains major challenges, i.e., ionic conductivity is inferior at room temperature. Therefore, recent...
Abstract Lithium metal batteries (LMBs) possessing ultrahigh energy density are promising next‐generation battery systems, but the short cycle life and safety concerns caused by uncontrollable growth of lithium dendrites impede their broad applications. Herein, to address these issues, an ultrarobust composite gel electrolyte (CGE) that can effectively stabilize ion deposition for LMBs is designed via fabricating a specially structured aerogel as matrix. The matrix with 3D interconnected...
Abstract The stringent demands for lithium salts make the design of “polymer‐in‐salt” type solid electrolyte restricted since it was proposed in 1993. Herein, a novel polymer‐in‐salt is developed via supramolecular strategy based on poly(methyl vinyl ether‐alt‐maleic anhydride) (PME) and single‐ion lithiated polyvinyl formal (LiPVFM)/lithium bis(trifluoromethylsulfonyl)imide (LiTFSI) composite (Dual‐Li). Hydroxyl LiPVFM Dual‐Li forms strong hydrogen bond with carboxylic acid group generated...

Sodium metal batteries (SMBs) are cost-effective and environmentally sustainable alternative to lithium batteries. However, at present, limitations such as poor compatibility, low coulombic efficiency (CE), high electrolyte cost hinder their widespread application.

Active plasmonic metamolecules under microscopic observation are promising for optical reporters in single molecule sensing applications. While self-assembled reconfigurable chiral can be conveniently engineered with functionalities, their is usually based on ensemble measurements, where the chiroptical response of enantiomers tend to cancel each other circular dichroism. Herein, we demonstrate enantiomeric switching individual active DNA origami-assembled metamolecules. The immobilized a...

This study reports a remarkably facile method to synthesize novel ionogels with imidazolium cycle crosslinks based on polyamidoamine (PAMAM) dendrimers via one-pot, modified Debus-Radziszewski reaction in ionic liquid 1-ethyl-3-methylimidazolium acetate ([EMIM][OAc]). High room temperature conductivity (up 6.8 mS cm-1 ) is achieved, and more remarkably, it can still exceed 1 when the dendrimer content reached 70% because PAMAM are completely amorphous many cavities newly formed contains...
Non-orthogonal multiple access (NOMA) has been studied as a promising technology for optical communication systems due to its superior spectral efficiency. However, the multi-user that employ NOMA with successive interference cancellation (SIC) suffer from error propagation (EP). Besides, issue of non-ideal rise and fall time received signal can result in severe bit rate (BER) degradation while decoding by SIC technique. In this paper, we propose straightforward two-stage program judgment...
