Abstract With advantages such as high theoretical capacity, low cost, and nontoxicity, Zn metal has been widely investigated an anode for aqueous batteries. However, the problems of dendrite formation sustained corrosion originating from severe interfacial side reactions uncontrolled electrodeposition in electrolytes significantly slows down practical application anodes. To address these issues, herein, anti‐corrosion elastic constraint (AEC) is introduced that built with nanosized TiO 2...
Abstract Aqueous Zn‐ion batteries (AZIBs) are promising for grid‐scale energy storage. However, conventional AZIBs face challenges including hydrogen evolution reaction (HER), leading to high local pH, and by‐product formation on the anode. Hereby bonds in aqueous electrolyte reconstructed by using a deep eutectic co‐solvent (DES) made of acetamide (H‐bond donor) caprolactam acceptor), which effectively suppresses reactivity water broadens electrochemical voltage stability window. The...

Abstract Lithium iron phosphate (LiFePO 4 ) is a widely utilized cathode material in lithium‐ion batteries, prized for its safety, low cost, and extensive cycling lifespan. However, compaction density limits application batteries requiring high volumetric energy density. The inclusion of conductive carbon black electrodes, while increasing porosity, also exacerbates side reactions due to specific surface area. In this study, the use liquid metal (GaIn) nanoparticles explored as substitute...
Abstract Prelithiation is a well‐established strategy for enhancing battery energy density.

Nickel-rich layered cathodes are promising for high-energy-density lithium-ion batteries but suffer from rapid capacity fading, primarily due to intergranular cracking and structural degradation during the H2-H3 phase transition, especially under high voltage. To address these challenges, a novel Ta5+/Ti4+ co-doping strategy has been introduced that simultaneously stabilizes grain boundaries enhances mechanical strength of cathode. The dopants effectively mitigate form pre-cation-mixing...
Abstract Aqueous Zn–LiMn 2 O 4 hybrid‐ion batteries are promising for large‐scale energy storage due to their high density, environmental friendliness, and low cost. However, conventional aqueous electrolytes suffer from two critical challenges: zinc anode side reactions manganese dissolution the LiMn cathode. To address these issues, a novel hybrid electrolyte regulated by methylsulfonylmethane (MSM) additive is introduced. This effectively suppresses dendrite growth promoting uniform Zn 2+...
Prelithiation is a well-established strategy for enhancing battery performance bymitigating the first-cycle active lithium loss.

Prelithiation is widely recognized as an effective strategy for prolonging battery cycle life. However, previous prelithiation typically involves adding limited lithium inventory (LiInv) to compensate initial LiInv loss solely, while neglecting the long-term cycling. We propose first time increase degree and pre-store stable LiCx enable sustainable replenishment which significantly extends life enhances energy density. To achieve this strategy, we developed Li-Mg-Al ultrathin alloy with...
