Abstract

A number of aspects relevant to the scale-up of all- solid-state, polymeric electrolyte, rechargeable lithium batteries have been studied. A nominal 1.7 Ah cell has been fabricated and cycled at 120 degrees C. At the 17 hour discharge rate, the initial cathode utilization, between voltage limits of 2.0 and 2.9 volts, is about 70% theoretical, falling to 20% after 50 cycles. The controlled production of the cathode material, V-6O-13, has been studied in detail. kg batches of pure material have been produced using a technique which may be utilized on an industrial scale. Thermal modelling studies have provided useful information regarding the potential thermal behaviour of cells. Small internally generated temperature rises are predicted for cells operating at rates consistent with vehicle traction applications. The effect of cell size and the role of inter-cell connectors have been evaluated in specific cases. Work to date indicates the importance of the particular duty or driving cycle in determining the effective thermal behaviour of cells and batteries
