New mobile charging tech is being developed by scientists that uses sunlight

Scientists at McGill University and Hydro-Québec’s research institute are developing a self-charging battery that can harvest and store energy using light. Their study shows that a standard cathode from a lithium-ion battery can be sensitized to light by incorporating photo-harvesting dye molecules.

They now need to build an anode, the storage component, to enable energy produced by the cathode to be transferred and stored. This will result in the world’s first 100% self-charging lithium-ion battery, which could be put to great use in smartphones, tablets, and other mobile devices, meaning users wouldn’t need to be near a plug in order to recharge their tech.
