The cathode comprises a First insertion material such as V6O13 and a minor proportion eg. <20% of a second insertion material eg. TiO2 whose discharge commences at a cell voltage above the threshold voltage at which irreversible changes occur to the first insertion material. The insertion materials may form a mixture or be chemically combined. The cell can be discharged to a voltage closer to the threshold voltage while still being reliably reversible, thereby maximizing energy output. |
