Objective
Objectives
In spite of many advantages (high energy- and power density, safety, low cost, and environmental acceptability) lithium polymer battery technology is unable to meet EUCAR performance targets for traction batteries. Overall advances needed in producing a 24 V, 25 Ah EV battery module with energy content of 0.5 kWh include:
Energy density in solid state lithium ion polymer battery cells: 150 Wh/kg
Power density in solid state lithium ion polymer battery cells: 150 W/kg An industrially feasible production process
Validation of the lithium ion polymer electrolyte technology for EV applications
Success in fulfilling EUCAR performance demands will be assessed in the final stage of the project.
Technical Approach
Critical aspects of the technology will be improved in efforts to meet EUCAR demands. These include:
Stability of solid polymer electrolytes
Electrode materials with improved specific energies
Manufacturing processes
Electrical management
Monopolar battery module design
Materials and processes will be developed for fabricating first laboratory cells, later entire monopolar batteries, and ultimately a complete 0.5 kWh EV battery module.
Expected Achievements and Exploitation
The project passes through a sequence of materials, component, cell and battery-module analyses, prior to evaluation according to EUCAR procedures. The following advances are expected:
Optimal specification of a carbon-based anode material (specific capacity: 375 Ah/kg).
Optimised specification of a lithiated oxide cathode material (specific capacity: 140 Ah/kg).
The specification of a lithium polymer electrolyte compatible with the selected electrode materials (ionic conductivity: 10-3S/cm; stability windows vs Li/Li+: 0-4.5V).
Cost-effective processes for lithium polymer battery electrode and cell component fabrication.
Laboratory scale test cells developed using the materials and processes arrived at earlier.
A 0.5 kWh EV battery module designed and manufactured at the Danionics A/S pilot line; test and identification of any process scale-up problems.
A complete assessment of the technical feasibility of EV battery production and cost estimates for EV production will be made.
