FlashBattery este bazată pe mici cristale naturale capabile să înmagazineze electricitate sau să emită lumină. Cristalele, numite NanoDots, au un diametru de doar doi nanometri și conțin lanțuri scurte de aminoacizi numiți peptide. Ele pot fi folosite pentru a acoperi „cavitățile” dintr-un electrod folosit într-o baterie standard.
La un capăt al electrodului, cristalele acționează ca un condensator care ajută la înmagazinarea de energie. La celălalt capăt ele trec energia în litiul bateriei la viteze mult mai mari decât în cadrul bateriilor standard.
