Solid Polymer Electrolytes for Next Generation Li-Ion Batteries |
| Description | Electric mobility represents the future for individual mobility on an environmentally friendly basis. The lithium-ion battery is considered the key technology for future electric engine systems. Lithium polymer batteries are promising materials devices, because they may overcome several problematic issues of the current technology. However, solid polymer electrolytes usually suffer from low ion conductivities at ambient temperature. New concepts demonstrate that high conductivities, comparable to commercial liquid electrolytes, are indeed achievable. The proposed project will investigate new block copolymer systems that are used as solid polymer electrolytes in Li-ion batteries. The project will involve a combination of materials synthesis, materials structure characterization by neutron- and X-ray scattering as well as electron microscopy, and the assembly of real battery cells for testing. Main goal of the project is to generate fundamental insights on controlling the nanoscale organization of solid polymer electrolytes; and thus advance their performance. Fellows will become familiar with the synthesis, fabrication and characterization of modern battery materials involving state-of-the-art neutron and complementary techniques, and develop a modern portfolio of skills in both academic and industrial settings. |
