Hydrated Eutectic Electrolytes with Ligand-Oriented Solvation Shells for Long-Cycling Zinc-Organic Batteries

Interface Engineering of CoS/CoO@N-Doped Graphene Nanocomposite for High-Performance Rechargeable Zn–Air Batteries

“…The advanced electrocatalysis technologies, such as water splitting, fuel cell and metal-air battery, have received increasing attention in the development of next-generation clean and sustainable energy devices [1]. The rechargeable Zn-air batteries (ZABs) are one of these new energy conversion and storage systems with great potential for large-scale applications due to its high theoretical power density, natural abundance of Zn, environmental friendliness, safety and low cost [2][3][4]. In rechargeable ZABs, oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are two critical electrochemical reactions during the discharge and charge operation, respectively [5].…”

Synergistic Manipulation of Zn2+ Ion Flux and Desolvation Effect Enabled by Anodic Growth of a 3D ZnF2 Matrix for Long‐Lifespan and Dendrite‐Free Zn Metal Anodes

“…Because a large energy consumption related to the desolvation process of [Zn(H 2 O) 6 ] 2+ in the aqueous electrolyte is required owing to its strong Coulombic interaction with the H 2 O solvation sheath, which may trigger the hydrogen evolution reactions. [ 26 ] The production of H 2 is accompanied by a localized pH increase near the reaction interphase and eventually promotes the generation of hydroxide sulfate Zn compounds, which are called “dead Zn” owing to the electronic insulator and non‐electroactive properties of deposits. [ 8 ] Herein, a 3D interconnected ZnF 2 matrix is proposed as a multifunctional protective layer to overcome the above two key issues simultaneously.…”

Non-concentrated aqueous electrolytes with organic solvent additives for stable zinc batteries

“…6,7 These features promote the recent renaissance of RAZBs with extensive researches on a variety of cathode materials, including manganese oxides, [8][9][10] Prussian blue analogues, 11,12 vanadium oxides, [13][14][15][16] and organic compounds. [17][18][19][20] Nonetheless, state-of-the-art RAZBs are plagued by the issues associated with metallic Zn anodes, such as low plating/stripping efficiency, dendrite growth, and unstable Znelectrolyte interface along with water-induced side reactions (e.g., H 2 evolution and surface passivation). 4,21,22 To address these challenges, an efficient strategy is constructing hierarchical structures [23][24][25][26] or modification layers [27][28][29][30] on Zn anodes.…”
