“…To avoid the hydrogen evolution problem in the coin cell test, [ 40 ] pouch battery was also assembled to test the performance of CBL@Zn anode in Figure S12, Supporting Information. For comparison, bare Zn anode exhibited large voltage polarization (over 200 mV) in the first few cycles and was short‐circuited after about 60 h. As for CBL@Zn anode, more than 160 h cycle life can be sustained with quite low voltage polarization (≈20 mV), which confirmed that this chemical buffer strategy could effectively improve the reversibility of Zn anode in alkaline electrolyte.…”

Rechargeable alkaline Zn–air batteries (ZABs) are attracting extensive attention owing to their high energy density and environmental friendliness. However, the dilemma of Zn anode, composed of ineluctable passivation and dissolution problems, severely hinders the discharge and cycling performance of the battery. Herein, the authors propose a chemical buffer layer coated on Zn metal (CBL@Zn) anode, in which ZnO nanorods are uniformly dispersed in graphene oxide (GO), to improve the reversibility of Zn↔ZnO electrochemical conversion process. Benefiting from the cooperative effect of ZnO nanorods’ nuclei role and GO's adsorption affinity, the electrochemical precipitation–dissolution behavior of insulated ZnO is chemically regulated and the Zn(OH)42− ions are effectively confined in the chemical buffer layer. Therefore, the symmetrical CBL@Zn‐CBL@Zn coin cell achieves a superior stability of 100 cycles with quite low overpotential (30 mv). When paired with commercial catalysts to assemble alkaline ZABs for practical use, an ultra high depth of discharge (DODZn) >98% and excellent 450‐h long‐term cycling performance are realized. This chemical buffer strategy can potentially provide a new insight for developing other highly reversible alkaline Zn‐metal batteries.

“…To date, lithium-ion batteries (LIBs) are one of the major energy sources. [1][2][3] With the rapid development of modern devices such as large-scale energy storage devices and electric vehicles, further improvement in energy/power densities, safety and lifespan are required for LIB. 4 Graphitic materials are the main commercial anodes because of their chemical stability, low operating voltage versus Li/Li + and low cost, but are still limited by their poor theoretical specific capacities (LiC 6 , 372 mA h g −1 ).…”

“…Copper [11], zinc [12], nickel [13], and chromium [14] are metals that can be metallized using various processes such as metal spray [15][16], metal paint [17][18], and electroless plating [19][20][21]. Because of the ease of the procedure, electroless plating is the most extensively utilized method among the previously stated ways in industry.…”

Electroless plating on Acrylonitrile Butadiene Styrene (ABS) is a metallization process that involves a reduction and oxidation reaction between the nickel source and the substrate material. The purpose of this research is to determine the ability of nickel deposition in the nickel electroless plating process with a specific etching time variation. This nickel electroless procedure begins with a chromic acid etching process that can last anywhere from 15 to 55 minutes and is useful for increasing roughness and creating submicroscopic cavities. After the etching process is finished, the surface roughness test is performed with a Mitutoyo SJ-210. Additionally, the activation step is carried out for 5 minutes in order for the polymer to become a conductor, allowing the plating process to proceed. The electroless plating process was then carried out for 55 and 75 minutes, with the goal of depositing nickel metal on the ABS surface. The coating results were analyzed using Fourier Transform Infrared (FTIR) spectroscopy IRSpirit/ATR-S serial No. A224158/Shimadzu to determine the functional groups formed both before and after the coating process, X-Ray Diffraction (XRD) to determine the character of the crystal structure, and phase analysis of a solid material using PANalytical type E'xpert Pro, To determine the surface morphology, the Zeiss EVO MA 10 was used to perform scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS) at 1000x magnification. The test findings demonstrate that, based on a range of investigations, etching variations of 15,25,35,45, and 55 minutes etching time 55 minutes are the best nickel deposited substrates, as evidenced by EDS data, where this treatment has the largest weight fraction of nickel. As a result, the longer the etching period, the rougher the surface becomes, affecting the capacity of nickel deposition to increase. Furthermore, it can be demonstrated in this investigation that the nickel deposited is in an amorphous form.
