which is a first for aqueous-based batteries.Till now there is no aqueous Zn-based battery that has crossed the 2V barrier.The energy density stored by this new high-voltage aqueous battery can be much higher compared to the currently dominant lithium(Li)-ion battery.Li-ion batteries have ...
The battery uses Zinc as a biodegradable metal anode, graphite as a nontoxic cathode material and paper as a biodegradable substrate. To facilitate additive manufacturing, we developed electrodes and current collector inks that can be stencil printed on paper to create water-activated batteries of ...

Aqueous zinc-ion batteries(AZIBs)hold vast potential for large-scale energy storage applications due to their intrinsic safety features.Vanadium-based cathodes,known for their high specific capacity,face dissolution issues primarily due to water activity at the cathode-electrolyte interface.Herein,we intr...
Since deliquescence or liquefaction seems a disadvantageous characteristic for heat storage materials, solid-state reaction is preferred for cyclability. In this case, however, the strain effect becomes a key factor. As well as the lithium-ion batteries (LIBs) or rechargeable magnesium batteries, the...
Electrodialysis (ED) is electric potential-driven membrane-based separation process. The basic principle of the membrane separation is similar to ion exchange reactions (Xu2005; Strathmann2010a). The charged groups are attached to the polymer backbone of the membrane material and it is obvious that...
Zn has been used as Zinc Sulphate in food additives [Food safety and standards, 2011a, Food safety and standards, 2011b]. It was omitted from the contaminant list of food product by food authority in India. The presence of metal ion and their concentration in various environmental samples ...
It could have less sludge volume, but it could release CO2bubbles and needs higher reagents for efficient precipitation83. Supplementary Table16lists some studies concerning carbonate precipitation. It can be seen that copper and manganese are the major metals removed by this technology. Zinc and lea...
A similar approach has been reported in membraneless zinc–bromine redox flow batteries, harnessing the phase separation in the electrolyte to suppress backward reactions like those occurring in our system32. An alternative approach to adding Na2Cr2O7 to the electrolyte is precoating the cathode (ex ...
the catalytic properties of biochar-based materials. For instance, Ohms et al. (1992) fabricated carbon-supported electrocatalysts for the ORR by using PAN as the nitrogen source, along with metal precursors such as metal sulfates (MSO4, where M=Fe, Co, Ni, Mn, Cu) and zinc chloride (...
