NEWS & TECHNOLOGY NEW MATERIALS Research cooperation aims at affordable energy storage for e-cars By Christoph Hammerschmidt THe HigH CosTs for batteries are regarded as a major and the M+W technology experts will contribute to optimize the roadblock for a broad introduction of electric vehicles. one of total energy system of cell and battery factories. in doing so, the reasons for the high costs is the complex manufacturing the researchers will get granular on the energy efficiency of the process for lithium ion batteries. The Karlsruhe institute of Tech- building as well as of the processes installed. At the same time, nology (KiT) and stuttgart-based M+W group have signed an they will increase the share of renewable energies in energy- agreement for research cooperation. The goal is to significantly intensive production. For instance, KiT experts plan to install a reduce energy and material costs in the battery production. photovoltaic system with integrated stationary energy storage The cooperation embraces research on drying room tech- at the KiT campus. Thus, it will become possible to establish nology, resource-efficient factory and manufacturing control a “green” cell production based on renewable energies. “M+W systems.

MiRiFisens is set out Reuniting no less than eighteen european research partners, to produce technological the project’s main objective is to develop a Quantum Cascade advances in TDLs in the Laser (QCL) light engine for sensing and security applications. MiR region addressing QCLs cover a broad portion of the mid-infrared (MiR) spectral crucial bottlenecks in QCL range - from 3 to 12 μm. This is an especially interesting range, technology, such as tuning as many chemicals of interest for safety and security have range, laser footprint, power strong characteristic absorption lines in that range which act as consumption and wall-plug MIRIFISENS conceptual fingerprints that enable their identification.
