Scientists from Bengaluru have made a breakthrough that could power the next generation of eco-friendly batteries.
The scientists from the Centre for Nano and Soft Matter Sciences (CeNS) have designed a cathode material which is suitable for the environment friendly Zinc battries.
“Significant advances in energy storage over the past few decades have been focused largely around lithium batteries because of their desirable performance – mainly high energy density, although they come with several environmental and safety risks during use,” the Department of Science and Technology said.
It added that as an alternative, recently, aqueous zinc-ion-based battery systems have been attracting attention due to their high energy storage capacity, safety, and environmental friendliness.
Researchers around the world are developing various cathode materials that can be suitable for zinc-ion-based electrolyte systems and can last for a long time with high energy storage capacity.
Several oxide materials are already being investigated in this regard, but have failed to demonstrate the required performance in zinc-ion-based systems due to many limitations.
To solve that, a research team led by Ashutosh Kumar Singh CeNS have come up with a new simple strategy to activate the cathode material by thermo-electrochemical treatment to modify its structure.
“This could help the batteries gain high energy storage performance. This represents a straightforward and efficient approach to enhancing the overall energy density and stability of the usual cathode materials,” the department said.
