Harvard boffins invent decade lasting battery
Harvard boffins have emerged from their smoke-filled rooms having invented a liquid battery which can last for a decade.
Most lithium-ion batteries are ready for silicon heaven after a few years. But Harvard researchers’ solution involves something called a flow battery.
It stores energy in liquid solutions which can last for over a decade by modifying the molecules in the electrolytes, ferrocene and viologen, so that they’re stable, water-soluble and resistant to degradation. When dissolved in water, the resulting solution only loses a percent of its capacity every 1,000 cycles. It could be several years before you even notice a slight drop off in performance.
