NEULIBE - Neuartige Lithium Ionen Batterien Elektroden

In 2001 the European Commission published the report "Future Needs and Challenges for Non-Nuclear Energy Research in the European Union", which summarises the outcome of eight expert workshops. In this report one of the future RTD priorities is to develop key enabling technologies. The lithium ion battery technology is described as one of the key enabling technologies in the aera of energy storage. Indeed, lithium-ion batteries have asserted themselves during the last 15 years in so-called 3-C market (camera, cell phone and computer). In this period the energy density has increased twofold what almost exclusively can be put down on technological progress, as for example increase of the density of the active masses, the usage of thinner separators or the application of thinner current collectors foils. This advancement and optimization of existing technology can be called evolution. The demand for high-energy and high-power lithium-ion batteries, which offer a high degree of safety, has been enhanced during the last years. In addition to the 3-C market that requires higher energy as well as a miniaturization of the cells for mobile devices, devices with high market potential like buffer batteries (for solar and wind power plants) and storage batteries for electric mobility (Hybrid Electric and Electric Vehicles) are in the spotlight. To accomplish the demands for these batteries concerning energy density, power density and safety, new battery materials and new, sustainable drafts are required (revolution).
