The RMIT team’s timing couldn’t be better. Their new proton battery has an energy density of 245 watt hours per kilogram, nearly three times the energy density of the team’s 2018 prototype. This energy density rivals that of conventional lithium-ion batteries, which typically have an energy density of around 260 Wh/kg.
Proton batteries use a carbon electrode and are charged by splitting water molecules.
“The main resource used in our proton battery is carbon, which is abundant, available in all countries, and cheap compared to the resources needed for other types of rechargeable battery such as lithium, cobalt, and vanadium,” said lead researcher and RMIT professor John Andrews in a statement.
Renewable energy?....not so renewable.

the intolerance of the old order is emerging from the rosy mist in which it has hitherto been obscured.
