Claim 1
Independent Claim
120 words
THE METHOD OF MAKING A BATTERY PLAQUE COMPRISING SINTERING A COMPARATIVELY THICK LAYER OF NICKEL FLAKES TO FORM A POROUS PLAQUE, SATURATING THE SINTERED PLAQUE SUBSTANTIALLY TO INFILL ITS PORES WITH A MELT OF A NITRATE SELECTED FROM THE GROUP CONSISTING OF CADMIUM NITRATE, NICKEL NITRATE AND MIXTURES THEREOF, COOLING THE PLAQUE TO SOLIDIFY THE NITRATE, HEATING THE SATUREATED PLAQUE UNDER A VACUUM AT A TEMPERATURE BELOW THE MELTING TEMPERATURE OF THE NITRATE TO DEHYDRATE THE NITRATE BY REMOVING ITS CRYSTAL WATER WHILE IT IS IN THE SOLID STATE WITHIN THE PLAQUE, CONVERTING THE DEHYDRATED NITRATE WHILE IN ITS SOLID STATE TO AN HYDROXIDE BY CATHODICALLY TREATING THE PLAQUE IN AN ALKALI METAL HYDROXIDE, AND COMPRESSING THE CATHODICALLY TREATED PLAQUE.
