A novel vacancy-rich, Al-doped MnO 2 cathode is proposed for AZIBs, showcasing 3D ion diffusion channels and excellent structural stability. It overcomes the trade-off between electrode kinetics stability, delivering impressive rate performance outstanding capacity retention.
Aqueous zinc-ion batteries (AZIBs) have emerged as one of the most promising candidates for next-generation energy storage devices due to their outstanding safety, cost-effectiveness, and environmental friendliness. However, practical application zinc metal anodes (ZMAs) faces significant challenges, such dendrite growth, hydrogen evolution reaction, corrosion, passivation. Fortunately, rapid rise nanomaterials has inspired solutions addressing these issues associated with ZMAs....
Abstract The practical application of all‐solid‐state lithium metal batteries (ASSLMBs) is limited by (Li) anode instability including Li dendrite formation and deteriorating interface with electrolytes. Here, a functional additive, isosorbide mononitrate (ISMN) non‐resonant structure (O 2 −N−O−) reported, which improves its reactivity utilized to build stable N‐rich solid electrolyte interface, effectively alleviating side reactions for poly(vinylidene fluoride) (PVDF)‐lithium...
Abstract Chloride ion batteries (CIBs) are a promising type of energy storage device due to their high theoretical volumetric density and abundant reserves chlorine‐containing precursors.
