"An RMIT-led research team has come up with an innovative way to make greener,
safer, recyclable “water batteries” that could replace common lead-acid
batteries.
There are three key components that make up a battery: a cathode, an anode and
an electrolyte. In common lithium-ion or lead-acid batteries, the electrolyte
is a liquid chemical solution that, once inserted, cannot be easily recovered.
The lead researcher, Prof Tianyi Ma, said his team’s water battery – known as
an “aqueous metal-ion battery” – addresses the issue by swapping out the
hazardous chemical electrolyte for water.
“It’s pure water. It’s the daily water we drink, but we do add additives to the
water like inorganic salts,” Ma said.
Ma said his battery operates comparably to current lead-acid batteries but can
be easily recycled without the risk of chemical pollution or the need for
specialist equipment and disposal facilities."
