Abstract

A method includes irradiating an energy storage device using an input radiation characterized by a first electromagnetic spectrum and detecting an output radiation reflected or backscattered by the energy storage device. The method also includes determining a second electromagnetic spectrum of the output radiation and comparing the second electromagnetic spectrum with a reference electromagnetic spectrum. The method further includes generating a sorting instruction based on comparison of the second electromagnetic spectrum with the reference electromagnetic spectrum.
