Abstract Rechargeable Zn‐ion batteries (ZIBs), prospective candidates for broad‐scale energy storage, still encounter many challenges such as hydrogen evolution corrosion, Zn dendrite growth, and capacity fading. Therefore, one specific strategy tuning the internal structure of solid polymer electrolytes (SPEs) via organic additives is proposed to address these urgent bottlenecks simultaneously. With trimethyl phosphate (TMP) addition, coordination environment 2+ in SPEs altered exists x (OTf − ) y coordinated molecules. Meanwhile, strong interaction between TMP enables preferential growth Zn(002) planes during electrodeposition, which proved based on first‐principles calculations, finite element simulations, multiple situ characterizations. Such excellent interfacial engineering forms electrolyte interface rich 3 (PO 4 2 fast ion conductor guarantees ultra‐long cycle life more than 6000 h a Zn|Zn symmetric cell at 0.1 mA cm −2 . Moreover, universality TMP‐modified shows 1000 times stable cycling VO (B)|Zn full cells 1 A g −1 under 0 °C with 95.24% retention, satisfies potential applications wide‐ranging storage solid‐state ZIBs.

Abstract Zinc (Zn) metal anodes of aqueous zinc‐ion batteries (AZIBs) have attracted significant attention due to their high theoretical capacities, low redox potentials, and cost. However, uncontrollable dendrite formation side reactions can result in limited reversible cycling quick failure the batteries. Herein, a polyvinylidene fluoride (PVDF)‐based protection layer (PVDF‐MXene) with β‐phase content is built by 3D printing method. The synergistic effect attributed approach MXene nanosheets contributes phase transition PVDF polymer chains from α‐phase β‐phase, improving ferroelectric properties printed films. Such manipulate concentration distribution zinc ions enable uniform growth plates. As result, symmetrical using such (PVDF‐MXene‐Zn) exhibit Zn plating/stripping voltage hysteresis at 1.0 mA cm −2 , mAh for over 4200 h, high‐rate capability up 10 . When assembled MnO 2 activated carbon, resulting Zn‐MnO battery capacitor exhibited significantly enhanced stability. proposed strategy this study provides novel anode, thus promoting practical application ZIBs.

Abstract The zinc (Zn) anode in zinc‐ion batteries suffers from potential defects such as wild dendrite growth, severe Zn corrosion, and violent hydrogen evolution reaction, inducing erratic interfacial charge transfer kinetics, which eventually leads to electrochemical failure.

Parlous structure integrity of the cathode and erratic interfacial microdynamics under high potential take responsibility for degradation solid-state lithium metal batteries (LMBs). Here, high-voltage LMBs have been operated by modulating polymer electrolyte intrinsic through an intermediate dielectric constant solvent further inducing gradient interphase. Benefiting from chemical adsorption between trimethyl phosphate (TMP) cathode, interphase rich in LiPFxOy LiF is induced, thereby ensuring structural interface compatibility commercial LiNi0.8Co0.1Mn0.1O2 (NCM811) even at 4.9 V cutoff voltage. Eventually, specific capacity NCM811|Li full cell based on TMP-modulated increased 27.7% 4.5 to V. Such a universal screening method solvents its derived electrode manipulation strategy opens fresh avenues quasi-solid-state with energy.

Constructing composite solid electrolytes (CSEs) integrating the merits of inorganic and organic components is a promising approach to developing high-performance all-solid-state lithium metal batteries (ASSLMBs). CSEs are now capable achieving homogeneous fast Li-ion flux, but how escape trade-off between mechanical modulus adhesion still challenge. Herein, strategy address this issue proposed, that is, intercalating highly conductive, homogeneous, viscous-fluid ionic conductors into robust coordination laminar framework construct electrolyte with conduction (LSE-HFC). A 9 µm-thick LSH-HFC, in which poly(ethylene oxide)/succinonitrile adsorbed by metal-organic nanosheets as building blocks, used here an example determine validity.
