Battery having two positive active materials
Patent
·
OSTI ID:6920210
A battery having positive and negative electrodes, a separator and an electrolyte, in which the positive electrode comprises a principal active material and secondary active material having a lower potential than the principal active material and a discharge product oxidizable by the principal active material is described. The secondary active material is present as an electrolyte impermeable masking layer which in the undischarged state isolates the principal active material from contact with the electrolyte and thereby provids improved stand and shelf life. The secondary active material is also present as a layer interposed between the principal active material and electrical contact means whereby the battery is characterized by a single potential discharge at the potential characteristic of the secondary active material discharged against the negative electrode.
