Enhancing the mechanical stability of interfaces in solid state Li batteries for energy-intensive applications

Tildelt: kr 4,0 mill.

The climate conference in Glasgow 2021 emphasized the importance of reducing CO2 emissions. This endeavor requires a more significant step towards sustainable energy sources and storage. The rationale for this project is to improve the next generation of emerging solid-state Li batteries (SSLBs), which can eliminate hazards and energy density issues associated with conventional liquid electrolyte-based Li-ion batteries (LIBs). To achieve this goal, five leading research groups and a large technological company in the EU have developed the following strategy to face the current challenges of SSLBs. We rely on multicomponent engineering of cathode material and its interface with the solid-state electrolyte to prevent stress-induced loss of contact during charge/discharge, which degrades electron/ion transfer, and thus improving the SSLB performance and longevity. Potential benefits are seen in the application of SSLB as true alternative to LIB to replace fossil fuels in the car industry. Project coordinator for the M-Era.Net project SOLMEC is from Autonomous University of Madrid in Spain. University partners are NTNU (Norway) and Montanuniversität Leoben (Austria). Research organisation partners are Centre for advanced materials application (Slovakia) and Agencia Estatal Consejo Superior de Investigaciones Científicas (Spain). The Industry partner is AVL List GmbH (Austria). During the first project period work has been focused on the design and characterization of CATs from blends of materials in specific geometries and morphologies to minimize volume expansion during cycling and the buildup of interface stress. Moreover, the required experimental methodologies to, e.g., characterise cross-sectional stress of SSLBs using synchrotron micro- and nano-beams at DESY in Hamburg and at ESRF in Grenoble has been established, respectively.
