LITHIUM ANODE LIMITED CYCLE SECONDARY BATTERY

Abstract

Solutions of NaPF6 in propylene carbonate or butyrolactone have conductivities sufficiently high to make them useful in cells. Stainless steels and aluminum resist corrosion in these solutions. Polyolefin and polyester nonwoven fabrics may be used as separators. Li anodes in propylene carbonate - NaPF6 show polarization increases of less than 200 millivolts during a 100 hour discharge at 10 ma/in to the 2nd. power and utilization of over 85% of active material. CuF2 electrodes may be discharged at 1 ma/in to the 2nd. power and utilization of 30% obtained with approximately 1.5 volts polar ization. Electrode test results were used to design, construct and test cells with Li anodes and CuF2 cathodes.
