new battery technology

A new battery technology that could significantly reduce the price of electric cars and home battery systems has taken a major step towards commercialisation.

The patented design uses non-toxic zinc and manganese, two metals that are abundant in Australia, and incombustible aqueous electrolyte to produce a battery with a high-energy density.

The researchers estimate the cost of this new electrolytic Zn–Mn battery to be less than US$ 10 per kWh compared with US$ 300 per kWh for current Li-ion batteries, US$72 per kWh for Ni–Fe batteries and US$ 48 per kWh for Lead–acid batteries.
