Title:
再充電可能なデュアルカチオン電気化学バッテリセル
Document Type and Number:
Japanese Patent JP2004513470
Kind Code:
A
Abstract:
A rechargeable battery cell (10) having high operating voltage and significantly increased specific capacity comprises a positive electrode member (13), a negative electrode member (17), and an interposed separator member (15) containing an electrolyte comprising a solution of a polyvalent cation solute in a non-aqueous solvent. The positive electrode member comprises an active material which reversibly takes up and releases the reactive polyvalent cation species during operation of the cell while the active material of the negative electrode contemporaneously reversibly releases into and takes up from the electrolyte solvent a monovalent cation species. Preferred cation species are those of alkaline earth metals, such as Y<3+>, and alkali metals, such as Li<+>.
