Technology that recycles old batteries to be used in home storage has been recognised in Australia

According to The Australian Financial Review, Crowley and co-founder Valentin Muenzel at Relectrify think they can reduce the upfront cost by about 30 per cent by recycling the best cells of spent electric vehicle batteries and connecting them via smart technology that draws power from the cells in a way that extends their lives and increases their efficiency.
If they can offer recycled cell batteries that last almost as long as new ones and cost a lot less, that will boost takeup, Crowley says. It would also reduce demand for greenhouse polluting grid power and battery waste.
They've previously raised $2 million and recycled a 12 volt battery for a caravan and driven it around Australia. The next step is field trials of a 48V home storage battery –  recycled from a spent Nissan leaf battery – with IBM and Selectronic, a maker of current inverters for solar systems. A 400V industrial and small utility scale battery is the next goal.
