HIGH-RATE NONAQUEOUS LITHIUM BATTERY

The theoretical basis of high-energy-density nonaqueous batteries is discussed with particular attention to the merits of lithium as an anode material. The development of a high-rate, high-energy nonaqueous battery is described. The electrochemical system employs lithium metal anodes and cupric chloride cathodes with an organic aprotic solvent electrolyte. The system has a theoretical energy density of 503 w-hr/lb compared to 208 for the silver-zinc system, one of the highest energy-density systems employed. Developmental efforts have gone primarily into the establishment of high rate capabilities with efficient performance over the range of rates from 10 to 60 min. Over this range of rates, for small 5 amp-hr cells, the energy-density (in w-hr/lb) improvement over the silver-zinc system ranges from 40 percent to almost 100 percent. Energy densities of 30-62 w-hr/lb have been demonstrated at discharge rates of 10-60 min employing small size 4-6 amp-hr cells. Some implications for future design of high-energy reserve-type batteries are discussed.
