Scientists Develop a Battery That Charges in a Quadrillionth of a Second

A prototype developed by Australia’s Commonwealth Scientific and Industrial Research Organisation can charge in a quadrillionth of a second, far faster than even the quickest modern phone batteries.

The quantum battery uses a “mirror sandwich” design. It stores only small amounts of energy and holds that energy for a short time, limiting its immediate practical use.

The prototype occupies little more space than a fingertip. Despite those limitations, the technology could eventually contribute to improvements in conventional batteries.
