Copper Nanoparticle-Modified Carbon Nanofiber for Seeded Zinc Deposition Enables Stable Zn Metal Anode

“…Energy storage technologies such as batteries have been widely used in various fields. Among different energy storage systems, aqueous zinc ion batteries (AZIBs) based on metallic zinc anodes were considered to be one of the most promising candidates owing to the high theoretical capacity (820 mAh g –1 ) and low reduction potential (−0.762 V vs SHE) of the Zn anode. − However, practical applications of AZIBs are hindered by the zinc dendrite, hydrogen evolution reaction, and corrosion. − Fortunately, many strategies have been used to overcome a series of problems and improve the electrochemical performances of zinc metal anodes, − such as 3D structure design, , electrolyte engineering, , artificial interface layers, , separators, and so on.…”

Rational design and regulation of tremella-like selenium-doped MoS2 for highly reversible sodium storage

“…Among these, the b values of the oxidation and reduction peaks of MoS 1.5 Se 0.5 @C are the highest at 0.79 and 0.91 when the discharge cutoff voltage is 0.2 V, demonstrating that the sluggish kinetics have been greatly improved by capacitive control. More accurately, the precise percentages of diffusion control and the capacitive mechanism can be identified using the following equation: 40 i ( V ) = k 1 v 1/2 + k 2 v i ( V )/ v 1/2 = k 1 + k 2 v 1/2 in which k 1 v 1/2 and k 2 v are the diffusion control and pseudocapacitance mechanism, respectively, and the adjustable values k 1 and k 2 are calculated using eqn (7). Based on these calculations, Fig.…”

“…Mn defects are formed by the charging process, and MnO with poor electrochemical activity for Zn 2+ is converted into a positive electrode with high electrochemical activity for AZIBs. Tang et al 46 prepared MnS/MnO@N-CF composites by a simple electrospinning method. The N-doped carbon fiber (abbreviated as N-CF) is generated during the carbonization of PVP, which greatly improves the electronic conductivity of the material.…”
