Say “NO” to those expensive Lithium-Ion Batteries and welcome this Environment-Friendly Rechargeable Proton Battery
Australian Researchers have demonstrated for the first time a working Rechargeable Proton Battery that could rewire how we power our homes, vehicles and devices. While the battery is just a small-scale prototype, it has the potential to be competitive with currently available lithium-ion batteries.
The rechargeable battery is environmental-friendly and has the potential to store more energy than currently available lithium-ion batteries.
Potential applications for the proton battery include household storage of electricity from solar photovoltaic panels. These batteries will soon be applicable for medium-scale storage on electricity grids.
The lead researcher Prof. John Andrews said that “Our latest advance is a crucial step towards cheap, sustainable proton batteries. It can help meet our future energy needs without further damaging our already fragile environment.”
“As the world is moving towards inherently-variable renewable energy to reduce greenhouse emissions and tackle climate change. The Proton Battery is one among many potential contributors towards meting this enormous demand for energy storage. This Proton Battery has the potential to be more economical than using lithium-ions, made from scare resources.”
“Carbon, primary resource used in our proton battery, is abundant and cheap compared to both metal hydrogen-storage alloys, and the lithium.” During charging the carbon in the electrode bonds with protons generated by splitting water with the help of electrons from the power supply. The Protons are released again and pass back through the reversible fuel cell to form water with oxygen from air to generate power. Unlike fossil fuels, the carbon does not burn or cause emissions in the process.
“Future work will now focus on further improving performance and energy density through use of atomically-thin layered carbon-based materials such as graphene, with the target of a proton battery that is truly competitive lithium-ion batteries firmly in sight,”Andrews said.
