HEMKoop

Project description

Range, quick charge, lifetime and cost of cover current lithium-ion batteries in electric vehicles currently only partially with the requirements of users and are therefore major barriers to electromobility. Therefore need to significantly improve these application properties and further cost reductions are achieved. Possibilities insist on the above property improvements with regard to the use of new so-called high-capacity Materials for the anode contact and their combination with high energy materials in the cathode contact of a battery cell. In terms of cost, new manufacturing processes, who refrain from energy-intensive and therefore expensive steps or significantly shorten the manufacturing process, big Reduction potential. This is where the joint project HEMkoop comes in. Objective of the project It is based on advanced active and passive materials the production of a so-called particulate active material Binder-carbon black composite material for high-efficiency electrode processing to explore. Economically sustainable material and Process concepts should be investigated and established in perspective, enable a short-term market entry can. In detail, a material and component side tuned high-energy battery cell to be developed. By improved formulations and process technologies are said to extend the life be further increased. It's supposed to be a process for processing high-energy materials to composite particles as well.

Subproject description

Their extrusion-based processing to electrodes examined become. At the same time, all steps should be taken later to the industrial scale be scalable. Due to the composite particles is a temporal decoupling (non-aging Stockpiling) and local separation of so-called Dispersion and coating for a robust and mass suitable Production possible. Consequently, a completely new process chain implemented and demonstrated for electrode production be reduced to shorter production times and significantly Costs (lower investment costs, 60 percent less energy, 60 percent less space requirement). The technology should also for Polymerelektrolyte- and, after minor adjustments also for so-called solid-state electrodes be applicable to future major changes in process technology to be able to avoid.
