“…The abundant Zn dendrites and dead Zn can dramatically widen the overpotential and polarization potential and finally cause the cell to fail. [ 6a,22 ] In comparison, the CF@Zn@C remains intact and smooth without observed dendrites (Figure 2d). The Zn is evenly deposited and filled into the sputtered carbon layer.…”

Despite the advantages of the fiber‐shaped Zn‐ion microbattery (FZMB) in powering wearable electronics, several fundamental challenges hinder its practical application, mainly including dendrite growth on Zn anodes (leading to short cycle life) and low electrical conductivity of cathode (resulting in poor rate performance). Herein, a facile approach of sputtering a nano‐thin conductive carbon layer on Zn anode to effectively suppress dendrite growth and a dual‐conductive polymer strategy to fabricate ultraconductive core‐sheath fiber cathode (poly(3,4‐ethylenedioxythiophene)‐poly(styrene sulfonate) (PEDOT:PSS) fiber@polyaniline nanobulges) are demonstrated. The carbon layer suppresses Zn dendrites by uniformizing surface electric field and providing abundant nucleation sites. The superior conductivity of the cathode is inherited from two conductive polymers (in particular, PEDOT:PSS fibers have an ultrahigh conductivity of 3676 S cm−1) and their strong intermolecular interactions. The resulting FZMB shows excellent stability (over 100% capacity retention after 3000 cycles) and supercapacitor‐level rate performance (73% capacity retention from 0.1 to 10 A g−1). Kinetics and mechanism studies reveal that the surface‐controlled dual‐ion migration mechanism is also correlated with the high rate performance. The corresponding quasi‐solid‐state device exhibits high stability under extreme deformation conditions and superior water‐proof capability (94.6% capacity retention after 12 h underwater immersion), demonstrating great practical application potential.

“…Solid‐state electrolytes such as poly(ethylene oxide) (PEO)–ZnX 2 complexes (X = Cl, Br, I, ClO 4 , and CF 3 SO 3 ), [ 134 ] poly(vinylidene fluoride)/PEO–Zn(CF 3 SO 3 ) 2 , [ 135 ] etc., have been introduced to physically shield dendrite growth but the low electronic conductivity in solid‐state electrolyte induced huge solid–solid interface impedance, which reduces the rate capability of ZIBs. Electrode interface designs such as the electrode surface coating [ 136,137 ] and application of 3D Zn hosts with conducting graphitic network, [ 138,139 ] as well as low‐current‐densities‐controlled electrohealing methodology [ 132 ] with slow galvanostatic discharge/charge appear to be economical approaches to eliminate the formation of zinc dendrite without degrading battery performance. [ 132 ] Nonetheless, the practical parameters such as current density, stripped and/or deposited capacity, and the interelectrode distance, which can significantly manipulate the Zn cycling performance, were usually not taken into consideration.…”

Zinc-ion batteries (ZIBs) have attracted intensive attention due to the low cost, high safety, and abundant resources. However, up to date, challenges still exist in searching for cathode materials with high working potential, excellent electrochemical activity, and good structural stability. To address these challenges, microstructure engineering has been widely investigated to modulate the physical properties of cathode materials, and thus boosts the electrochemical performances of ZIBs. Here, the recent research efforts on the microstructural engineering of various ZIB cathode materials are mainly focused upon, including composition and crystal structure selection, crystal defect engineering, interlayer engineering, and morphology design. The dependency of cathode performance on aqueous electrolyte for ZIB is further discussed. Finally, future perspectives and challenges on microstructure engineering of cathode materials for ZIBs are provided. It is aimed to provide a deep understanding of the microstructure engineering effect on Zn 2+ storage performance.

“…The carbon-based materials such as CNTs, [241] rGO, [242] and carbon black [243] have also been proposed as the suitable candidates for the coating of Zn anode to minimize the issues associated with Zn. The experimental and theoretical studies show that the CNT coating completely inhibits the dendrite formation due to its charge redistribution effect on overpotential.…”

The growing demand for the renewable energy storage technologies stimulated the quest for efficient energy storage devices. In recent years, the rechargeable aqueous zinc-based battery technologies are emerging as a compelling alternative to the lithium-based batteries owing to safety, eco-friendliness, and cost-effectiveness. Among the zinc-based energy devices, rechargeable zinc-ion batteries (ZIBs) are drawing considerable attention. However, they are plagued with several issues, including cathode dissolution, dendrite formation, etc.. Despite several efforts in the recent past, ZIBs are still in their infant stages and have yet to reach the stage of large-scale production. Finding stable Zn 2 + intercalation cathode material with high operating voltage and long cycling stability as well as dendrite-free Zn anode is the main challenge in the develop-ment of efficient zinc-ion storage devices. This Review discusses the various strategies, in terms of the engineering of cathode, anode and electrolyte, adopted for improving the charge storage performance of ZIBs and highlights the recent ZIB technological innovations. A brief account on the history of zinc-based devices and various cathode materials tested for ZIB fabrication in the last five years are also included. The main focus of this Review is to provide a detailed account on the rational engineering of the electrodes, electrolytes, and separators for improving the charge storage performance with a future perspective to achieving high energy density and long cycling stability and large-scale production for practical application.
