Orientation guidance has shown its cutting edges in electrodeposition modulation to promote Zn anode stability toward commercialized standards. Nevertheless, large‐scale orientational deposition is handicapped by the competition between Zn‐ion reduction and mass transfer. Herein, a holistic electrolyte additive protocol is put forward via incorporating bio‐derived dextrin molecules into a zinc sulfate...
The introduction of electrolyte additives is one of the most potential strategies to improve the performance of potassium metal batteries (PMBs). However, designing an additive that can alter the K+ solvation shell and essentially inhibit K dendrite remains a challenge. Herein, the amyl‐triphenyl‐phosphonium bromide was introduced as an additive to build a stable solid electrolyte interphase layer...
Aqueous zinc ion batteries (ZIBs) are regarded as one of the most ideally suited candidates for large‐scale energy storage applications owning to their obvious advantages, that is, low cost, high safety, high ionic conductivity, abundant raw material resources, and eco‐friendliness. Much effort has been devoted to the exploration of cathode materials design, cathode storage mechanisms, anode protection...
Aqueous zinc‐ion batteries (ZIBs) have been extensively studied due to their inherent safety and high energy density for large‐scale energy storage. However, the practical application is significantly limited by the growing Zn dendrites on metallic Zn anode during cycling. Herein, an environmental biomolecular electrolyte additive, fibroin (FI), is proposed to guide the homogeneous Zn deposition and...
Although aqueous zinc–ion batteries (ZIBs) are promising for scalable energy storage application, the actual performance of ZIBs is hampered by the irreversibility. Optimization of electrolyte composition is a relatively practical and facile way to improve coulombic efficiency (CE) and Zn plating/stripping reversibility of ZIBs. N,N‐Dimethylacetamide (DMA) has a higher Gutmann donor number (DN) than...
Aqueous zinc‐ion batteries are a low‐cost and safe energy storage system, but suffer from detrimental side reactions and Zn dendrites due to the strong interactions between Zn2+ and water molecules in the electrolytes, and random Zn2+ deposition on the anode surface. Here, an electrolyte involving a dual‐functional additive of polyethylene glycol (PEG) to bypass these issues is reported. The electrolyte...
