The US Navy is has created a rechargeable aqueous zinc battery with performance approaching Li-ion cells. While useful in non-rechargeable applications – it is the basis for ‘alkaline cells’ – zinc electrodes tend to grow dendrites (whiskers) when charged, wrecking the cell. Scientists at the US Naval Research Laboratory (NRL) have created nickel-zinc batteries with ...
