DRX illustration (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption Illustration of a DRX cathode's "disordered" atomic structure (right) versus the "ordered" atomic structure of a conventional cathode. A disordered cathode structure can store more lithium - which means more energy - while allowing for a wider range of elements to serve as the transition metal.
