A renewable biomass-based lignin film as an effective protective layer to stabilize zinc metal anodes for high-performance zinc–iodine batteries

Abstract

Aqueous rechargeable zinc-iodine (Zn-I2) batteries with high security and low cost have been considered as a promising candidate for energy storage instruments in recent years. Nevertheless, the commercial application of...

Highly Reversible Zn Metal Anodes Realized by Synergistically Enhancing Ion Migration Kinetics and Regulating Surface Energy

“…In response, many efforts have been devoted to tackling the dendrite growth and eliminating interfacial parasitic reactions, involving optimizing electrolyte composition, [ 11–16 ] 3D architecture modulation design, [ 17 ] and interface modification engineering. [ 18,19 ] Concerning feasibility and practicability, artificial interfacial modification between the Zn anode and the liquid electrolyte is deemed a versatile and promising approach. To date, interfacial modification strategies such as physical change of Zn surface with protection layers (e.g., Si 3 N 4 , [ 20 ] BaTiO 3 , [ 21 ] and g‐C 3 N 4 , [ 22 ] ) and in situ chemically synthesizing multifunctional interface on Zn anode (e.g., organic acid etching Zn, [ 23 ] self‐assembly of MXene [ 24 ] and TCNQ@Zn [ 25 ] ) have been exploited.…”

Stripy zinc array with preferential crystal plane for the ultra‐long lifespan of zinc metal anodes for zinc ion batteries

“…On the one hand, the nanosized protective layers are often carried out through chemical vapor deposition and magnetron sputtering, 33,34 which are expensive and time consuming and insufficient to restrain the generation of Zn dendrites because of poor mechanical performance. On the other hand, the microsized passivation layers can increase the interfacial resistance and nucleation overpotential during the plating and stripping processes, which would deteriorate the rate performance and hinder Zn ion batteries from practical application 35 . For example, He et al fabricated Al 2 O 3 coating by atomic layer deposition technique to enhance the electrochemical performance of Zn metal anodes 33 .…”

Dynamically Responsive and Ionic Conductive Gel Coatings to Realize the Stable Circulation of Zinc Metal Anodes for Zinc-Ion Batteries

“…4 These disadvantages lead to low coulombic efficiency (CE), weak circulation lifetime, and short circuits, which eventually hinder the commercial application of Zn-ion batteries. 5 At present, numerous solutions have been employed to address these problems, involving electrolyte optimization (additives, 6,7 Zn salt, 8,9 and organic solvents 10 ), surface coating (organic, 11 inorganic, 12−14 and organic/inorganic layers 15 ), and Zn deposition carrier engineering (porous conductive framework 16−18 ). Among these strategies, constructing an artificial surface protective film is a direct and efficient way to suppress the dendrite formation, hydrogen evolution, and corrosion reaction on Zn anodes throughout the repeated plating/ stripping cycles.…”
