Li-ion batteries with "nickel" as the main material or the highest ratio material on the cathode or anode electrode have attracted considerable attention. Nickel has high strength and corrosion resistance. Nickel has also been utilized successfully as the cathode and anode materials. The specific capacity and energy and power density of the material increased with increasing nickel content. However, several problems have limited the use of nickel-based Li-ion batteries. Problems such as cation mixing, the properties of nickel, and highly Ni-rich compounds leading to side reactions, influence the electrochemical performance of Li-ion batteries. The morphology is another factor affecting the electrochemical performance. Further studies will be needed to synthesize materials with the desired morphology and determine how the morphology affects the electrochemical performance. In a morphological perspective, extensive morphological adjustments are a pathway to a long and stable life cycle. In this light, nickelbased electrodes are manufactured continuously and will always be considered for next-generation secondary energy storage. The morphology of nickel-based active materials is one of the main factors determining the highperformance of Li-ion batteries.

“…14 Finally, due to similar radii of Ni 2+ (0.69 Å) and Li + (0.76 Å), Ni 2+ can be incorporated into active sites and reduce lithium transport in the layered structure. 16 To mitigate the above issues, several strategies have been attempted: doping, 17−19 surface modification, 20 surface modification via intentional electrolyte additive decomposition, 21−23 process refinement, 24,25 TM concentration gradient, 26 core−shell structures, 27 grain boundary tailoring, 28 and single-crystalline morphology. 29,30 modifications fail to generate nickel-rich cathode materials with optimum cycle life retention and air stability for commercial use.…”

Nickel-rich cathode materials are quickly becoming the next commercial cathode for electric vehicles; however, their long-term cycle life retention and air stability remain a barrier to the use of these lower-cost, higher-energy density materials. Surface reactivity and mechanical degradation, especially at high voltages, remain two issues that impede these material’s commercialization. While surface treatments have shown great promise in reducing surface reactivity, mechanical degradation or “cathode cracking” persists yet. In the present work, LiNi0.9Mn0.05Al0.05O2 (NMA) cathode materials are first pulverized into their primary particle constituents and then coated with lithium phosphate via solution-based chemistry with varying concentrations of phosphoric acid. The cathodes are characterized using energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, transmission electron microscopy, electrochemical impedance spectroscopy, and electrochemical cycling. After 100 cycles, the pulverized NMA cathodes coated using the lowest concentration of phosphoric acid show delayed voltage decay and double the discharge capacity compared to the pristine material in full cells during high-voltage cycling.

“…Recently, the aqueous zinc−ion hybrid supercapacitor (ZIHS), with a capacitor‐type cathode and battery‐type anode, has been proposed and developed [ 1–6 ] due to its high energy density and power density. In the researches of capacitor‐type cathodes, activated carbon (AC) is considered as an ideal energy‐storage material because of its excellent electrochemical stability, high conductivity, and low cost.…”

The nonuniform zinc nucleation process on the surface of zinc metal anodes is known to result in irreversible dendrite growth, which brings the risk of short circuit for the zinc‐ion hybrid supercapacitor (ZIHS). Herein, a conductive carbon−zinc composite anode with dense active sites is reported to achieve controllable dendrite growth. This unique modified anode in the ZIHS enables extremely low polarization (47 mV) in the symmetric battery test and delivers excellent application performance (capacity retention of 97.7% for 10 000 cycles). In addition, the changes in crystallographic orientation and morphological characteristics of the zinc electrode during deposition are observed by ex situ analysis. The improved zinc nucleation pattern of the modified anode verifies that the carbon additive can significantly facilitate isotropy in Zn deposition. Such a successful application of this economic and expandable modification strategy shows that carbon additives have significant potential in improving the stability of the anode.
