Scientists from the universities of Alberta and Toronto have unveiled plans for a leak-proof quantum battery they said could be built using existing technology. They used a symmetrical open quantum network to store excitonic energy and proved the energy could be stored without loss in what they called a dark state. The researchers say their device is more efficient than current lithium-ion batteries because it uses less material per unit of energy. Discharging the battery’s energy would involve a controlled break-up of the network’s structure. The scientists are now researching charging, discharging and scaling up their battery for practical uses.
