Exoelectrogens, coated on anodes, consume the wastewater remaining organic pollutants and, in the process, generate electricity.
Batteries have called two electrodes an anode and a cathode. The anodes in most of today's lithium-ion batteries are made of graphite.
The theoretical maximum storage capacity of graphite is limited very at 372 milliamp hours per gram hindering significant advances in battery technology said Vilas Pol an associate professor of chemical engineering at Purdue University.
The researchers have performed experiments with a porous interconnected tin-oxide based anode which has nearly twice the theoretical charging capacity of graphite.
The researchers demonstrated that the experimental anode can be charged in 30 minutes and still have a capacity of 430 milliamp hours per gram (mah g 1)
The anode consists of an ordered network of interconnected tin oxide nanoparticles that would be practical for commercial manufacture
"Re-grown hematite proved to be a better power generating anode, producing a record low turn-on voltage that enabled the researchers to be the first to use earth-abundant hematite
These types of batteries, in all of their different lithium-anode combinations, continue to be an essential part of modern consumer electronics
