The application of supported liquid membrane separators to alkaline secondary batteries
A new separator technology under development utilizes the highly specific transport properties of select organic reagents to provide what is, at least in principal, the ideal alkaline battery, separator. In the case of Ni-Zn cells, by providing a membrane that transports hydroxyl ions and rejects zincate ions the possibility of dendrite shorting is eliminated and, furthermore, attendant benefits may be obtained in zinc shape changes by controlling water transport during charge and discharge. Laboratory Ni-Zn test cells incorporating supported liquid membrane battery separators have been cycled extensively. Cells routinely operate over 100 cycles at moderate current densities. Possible benefits to other alkaline systems such as Ni-Cd and Ag-Zn are also discussed.
