The Photon Battery is an all-optical battery that stores light energy. Photon Batteries are typically designed for extreme environments requiring non-flammable safety, decades long shelf life, instantaneous charging times and millions of recharge cycles. The technology was invented by Alex Diggins in 2015 and is now in commercial development by Nimbus Engineering Inc. (link to CrunchBase in references)

In a standard Photon Battery cell, photons are stored in metastable electron states as electrostatic potential energy. A Phosphorescent material such as Strontium Aluminate can be used as the energy storage material. This material is usually illuminated by an artificial light source while charging such as GaN LEDs. Efficient GaN LED pioneered by Nakamura and others have recently made Photon Batteries possible and efficient. Similarly, Strontium Aluminate developed by Matsuzawa has made storing energy in commercially available phosphors economically viable. Once fully charged, phosphor material can be controlled to emit light onto photovoltaic layers such as thin film solar cells to produce power.
