LITHIUM-NICKEL FLUORIDE SECONDARY BATTERY INVESTIGATION.
Abstract
The selection of one lot of NiF2 to be used in preparing positive electrodes for factorial testing, was made based on a comparison of the exchange currents, I sub o, obtained from electrodes prepared with various lots of NiF2. The first set of twenty-one positive electrodes for factorial testing have been prepared using various combinations of conductive diluents, binders, and extenders. This will allow a correlation to be made between electrode makeup, physical properties, and electrochemical behavior. Electrolyte studies, using new solute/solvent pairs, have continued. Plots show that a completely dissociated electrolyte has not been found and that ion-pairing is also present. A cell, which failed after being on automatic cycling for seventy-two cycles, was disassembled. The positive electrode and some material which had flaked off the electrode were analyzed for Ni, NiF2, and Ni(PF6)2. None of the latter was found either in the plate or in the 'sludge'. (Author)
