Within the scope of the project “HyBaCap – Hybridation of battery and supercapacity electrodes with high-performance electrolytes for mobile energy storage modules”, Robert Bosch GmbH, Leibniz-Institut für neue Materialien gGmbH INM and IoLiTec Ionic Liquids Technologies GmbH are collaborating to develop a new, powerful, electrochemical, hybrid energy storage system. With a high performance of more than 10 kW/kg combined with a high capacity of more than 50 Wh/kg, this new technology is to supersede the current energy storage technologies.

The aim of the project is to increase the capacity of super capacitators through the hybridisation of porous carbon on a nanoscale level with battery electrode materials. At the same time, a performance level is to be achieved which significantly outperforms that of conventional batteries. Due to the fact that the new energy storage system will also be able to achieve high cyclical stability even at temperatures of up to 100° Celsius, the finished product should be particularly suitable for use in the mobile storage systems of electric vehicles.

The project is to be realised by optimising every aspect of the cells of the new energy storage system. Newly developed materials for the electrodes, such as new nanoporous carbons that are as low-cost as possible, and 2D nanolamellar metal carbides, such as the newly developed MXene, will be used. The HyBaCap project will involve examining the interplay between the different components as well as analysing the costs and the cost-effectiveness of the new energy storage system.

The project HyBaCap is being funded by the Federal Ministry for Economic Affairs and Energy (BMWi) from December 2016 until November 2019.
