Lithium-Ion Batteries (LIBs) are considered too expensive, have a too short service life and are not designed for pulsed applications. In addition, there are problems with applications at high temperatures (> 60 °C). The HyBaCap cells are designed to meet the requirements of electromobility by targeted optimization of the anode, cathode and electrolyte.
The HyBaCap project aims to develop efficient electrochemical hybrid energy storage systems that combine high power (> 10 kW/kg) with high energy (> 50 Wh/kg). By nanoscale hybridization of porous carbon and battery electrode materials, a higher energy is achieved compared to super capacitors but at the same time a higher performance compared to batteries. The complementary expertise of Bosch (cathode), INM (anode) and Iolitec (electrolyte) will thus be used to achieve holistic optimization for the first time.
Starting point for the cell materials are commercial activated carbon and conventional electrode materials which must be mixed on a nanoscale level to optimize performance. In order to achieve maximum performance parameters, novel electrode materials, especially 2D nanocarbides (MXene) and optimized nanocarbons with optimized pore structure as well as high-performance electrolytes (ionic liquids) are evaluated. All processes are accompanied by parallel cost analyses and economic efficiency studies.
