Abstract:
1. An electrochemical cell, comprising as at least part of an anode, a lithium transition metal oxide compound which has a [B as at least part of a cathode, a compound with a structure type other than a lithium-metal-oxide spinel-type structure or a lithium-metal-oxide layered-type structure; and an electrically insulative, lithium containing, liquid or polymeric, ionically conductive electrolyte between the anode and the cathode, such that, on discharging the cell, lithium ions are extracted from the spinel-type framework structure of the anode, with the oxidation state of the metal ions of the anode thereby increasing, while a concomitant insertion of lithium ions into the compound of the cathode takes place, with the oxidation state of the metal ions of the cathode decreasing correspondingly.
