Abstract Aqueous zinc‐ion batteries are promising for next‐generation energy storage systems. However, the zinc dendrite growth, corrosion, and hydrogen evolution reaction at electrochemical interface severely impede their further development. Herein, a Zn 2+ ‐rich H 2 O‐poor Helmholtz plane is constructed to regulate between anode electrolyte. Electrochemical in situ spectroscopy characterizations reveal that designed electric double layer with abundant coordination sites less O content can facilitate rapid electron transfer, homogenize deposition, alleviate side reactions induced by active O. Benefiting from high reversibility stability of anode, Zn||Zn symmetric cell be cycled over 1000 h 1 mA cm −2 Zn||NH 4 V 10 full maintain capacity 85.23% cycles 3 A g −1 .

Abstract Li plating is widely known as the key factor leading to degradation and safety issues in lithium‐ion batteries (LIBs). Herein, feasibility of monitoring onset progression proposed justified graphite/LiFePO 4 pouch cell by an operando impedance‐thickness combinational technique. First, a proof‐of‐concept, real‐time thickness/impedance variations LIBs during charging at low temperature (≈0 °C) are obtained dissected. Three distinct stages corresponding different patterns observed with critical changing points charge‐transfer resistance, which match well counterpoints differential thickness/capacity curves. Post‐mortem analysis Mass Titration Scanning Microscopy also indicate that these intercalation, nucleation & nuclei growth, dendrite respectively. Thereafter, cycling protocols carried out test as‐mentioned processes this novel The results disclose extensive deposition metallic significantly intensifies loss inventory, aging or even “capacity plunge”, depict safer boundary plot about preventing occurrence “Li plating” region. This work provides new insights on behavior battery control under harsh operational conditions.

Abstract Lithium‐ion batteries (LIBs), as efficient electrochemical energy storage devices, have been successfully commercialized. Lithium plating at anodes has attracting increasing attention advance toward high density and large size, given its pivotal role in affecting the lifespan, safety, fast‐charging performance of LIBs. mostly happens during fast charging or low temperatures. However, external pressure is often overlooked an essential factor that influences lithium This review analyzes discusses influence on for commercial LIBs, with a particular focus plating. Recent advances this topic, including experimental results mechanism analyses, are reviewed. explored by examining internal morphology behavior batteries. It emphasized affects through ion transport, electron their heterogeneities, thereby risk Subsequently, rationale mitigating elucidated from perspective optimization inside Overall, provides valuable insights into practically guiding rational design development.

Abstract With the development of electric vehicles, exploiting anode materials with high capacity and fast charging capability is an urgent requirement for lithium‐ion batteries (LIBs). Borophene, merits capacity, electronic conductivity diffusion kinetics, holds great potential as LIBs. However, it difficult to fabricate intrinsic electron‐deficiency boron atom. Herein, heterogeneous‐structured MoB 2 ( h ‐MoB ) amorphous shell crystalline core, prepared by solid phase molten salt method. As demonstrated, core can encapsulate honeycomb borophene within two adjacent Mo atoms, accommodate more lithium ions strengthen storage kinetics. According theoretical calculations, adsorption energy in about −2.7 eV, barrier calculated be 0.199 guaranteeing enhanced kinetic behavior Li + ions. a result, presents 798 mAh g −1 at 0.1 A , excellent rate performance 183 5 long‐term cyclic stability 1200 cycles. This work may inspire ideas fabrication analogs two‐dimensional metal borides.
