The research described in this proposal aims to develop a new Li-ion cell for traction purposes with the following characteristics:

  • High energy density of at least 200 Wh/kg
  • Low costs i.e., a maximum of 150 Euro/kWh
  • Improved safety

Although the Li-ion cell appears to be the most appropriate technology to meet these goals, considerable research and development is required. For example, the much-used LiFePO4 cells cannot reach the energy density criterion, and in addition, LiFePO4 is patented, which hampers worldwide commercialization. Many other materials are either too expensive or do not meet current safety, environmental standards (e.g., cobalt in LiCoO2). Thus, we propose a shift from carbon to the much higher capacity siliconbased anodes, and from cobalt-based to iron and/or manganese/nickel-based cathodes, and to use novel electrolyte salts. Ecodesign and recycling are inherent parts of the project.
