No battery is yet capable of affordably storing and releasing significant volumes of electricity. Lithium-ion batteries are sufficiently mature to have developed a competitive edge for some uses, but flow batteries hold greater potential for meeting expectations for grid scale storage, should their cost and technical challenges be overcome. Other lithium based technologies are being intensively explored. ...
