Electrochemical transformation reaction of Cu–MnO in aqueous rechargeable zinc-ion batteries for high performance and long cycle life

Abstract

Rechargeable aqueous zinc-ion batteries (ZIBs) are emerging as alternative lithium-ion batteries for large-scale energy storage applications due to their safety and environmental friendliness. However, their applications are hindered by the...

The origin of capacity fluctuation and rescue of dead Mn-based Zn–ion batteries: a Mn-based competitive capacity evolution protocol

“…12,46,47,51 It is worth noting that the capacity fluctuation phenomenon is ubiquitous in previously reported Mn-based ZIBs (Table S4, ESI †). 12,15,23,30,47,49,[51][52][53][54][55][56][57][58][59][60] For example, MnO xÀ2 reported by…”

Electrochemical reaction behavior of MnS in aqueous zinc ion battery

“…So far, the most attention has been paid to Prussian blue analogues, manganese, vanadium, molybdenum, and organic cathode materials. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Among them, manganese-based compounds are considered as one of the most promising ones due to their competitive advantages of environment-friendliness, costeffectiveness, low toxicity, multiple valence states, and tunable structure/function. 3,4,14,18,27 Manganese oxides have been widely studied as zinc ion battery cathode materials and inspiring progress has been made.…”

“…3,4,14,18,27 Manganese oxides have been widely studied as zinc ion battery cathode materials and inspiring progress has been made. 4,14,[16][17][18][28][29][30][31] Most recently, MnS x , which is known as another important manganese-based compounds, has also been introduced in zinc ion batteries. 7,8,32,33 For instance, Chen et al activated Zn-inactive MnS by in situ electrochemically converting it into Mn oxides in zinc ion battery.…”

Enhancing the Electrochemical Performances by Wet Ball Milling to Introduce Structural Water into an Electrolytic MnO2/Graphite Nanocomposite Cathode for Zinc-Ion Batteries

“…The electrostatic interaction between the Zn 2+ and MnO 2 frame is reduced by the presence of structural water, effectively promoting ion diffusion. 45,46 In this paper, it was found that structural water on the (102) and (110) crystal planes enhanced the electrochemical performance of zinc-ion batteries by improving the ion diffusion ability. The study on the introduction of structural water by wet-high-energy ball milling will provide a novel idea for the development of manganesebased oxide cathode materials.…”
