Objectif The major bottleneck for battery driven electric vehicles is the battery. Existing battery types all have their specific drawbacks: lead acid batteries give EV a short range of only 60 km, Na/S operate at 300 C and NiCd batteries contain poisonous Cd and are expensive. Li batteries may give EV a range of 200-300 km, operate at room temperature and are expected to be cheap. The EC programme therefore focuses on the development of different concepts for Li batteries. The aim of this project is to improve the energy density and the cycle life and reduce the cost of lithium polymer battery laminates by applying the swing electrode system with a new type of electrolyte. The target at the end of the project is to build a 24 V and 40 Ah prototype battery module on a pilot production line. A new type of rechargeable lithium polymer cell with high cell voltage (>3 V), the so-called swing electrodes concept is under development.The swing electrodes consist of two lithium intercalating compounds using e.g. carbon on the anode and e.g. a manganese dioxide on the cathode side, separated by a polymer electrolyte. The lithium cations move in the electrolytes from one host structure to the other. Development of battery laminate based on the combination of a new liquid polymer electrolyte and these electrode rnaterials are in progress within the EC project JOUE-CT91-0073. It is envisaged that at the end of this project, a range of materials and processes have been demonstrated on a pilot production line.This project aims at implementing the improved materials and processes in the pilot production line and to manufacture lithium polyrner batteries in large quantities for quality improvement necessary for building 1 kWh batteries. The main tasks are divided between the participants as follows: - Innovision manufactures lithium polymer electrolytes for incorporation of the swing electrode materials. - Innovision manufactures swing electrode materials for incorporation in the lithium polymer battery. - Delft University of Technology makes thin film intercalation electrodes improving cathode performance - University of Southampton investigates additives improving anode cyclability. - University of St. Andrews investigates composite cathode enhancing material utilization and rate capability. - Innovision develops the processes for making new composite electrodes. - In a laboratory production, test cells will be fabricated by Innovision. - Design and construction of batteries will be done by Innovision. - All participate in test and evaluation of cells and batteries.
