HyBaCap - Hybridisation of battery and supercapacitor electrodes with high-performance electrolytes for mobile energy storage modules
Overview
Background & policy context:
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.
Objectives:
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.
Methodology:
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.
