The new ZCell battery is ‘unique’ as it does not use lithium – it is based on a zinc-bromide solution – and can store 10kWh of electricity. ‘The active parts are plastic, aluminium and steel, the fluid electrolyte can be removed and cleaned and put in the next battery so the whole thing is very recyclable,’ explains executive chairman Simon Hackett.

The battery is capable of powering a household for two days and is roughly the size of an air conditioning unit, which can be installed either inside or outside a residence. Though no official price has been announced yet, industry specialists put it at around UAS$10 000.

An estimated 8000 tonnes worth of lithium-ion batteries are thrown away every year, says the Australian Battery Recycling Initiative. It expects figures will surge to 150 000 tonnes by 2035. At the moment, 1.5 million homes across the country are said to feature solar panels.
