Project PERLA ERC 2022
The project aims to develop electroconductive fluids containing anisotropic particles. Their novelty lies in the formation of dynamic networks established within the flow of fluids. We plan to validate fundamental hypotheses related to the out-of-equilibrium percolation of anisotropic particles in flows. This acquisition of fundamental knowledge will allow proposing new concepts for the development of low-viscosity, highly conductive, and tunable conductive fluids. Carbon nanotube systems and short carbon fibers will be used as conductive particles, both brownian and non-brownian.
The structure, rheological, and electrical properties of the suspensions will be characterized under different flow conditions, ranging from diluted to concentrated regimes, including liquid crystal phases. The fundamental knowledge gained in the project will be applied in various applications, including flow capacitors, water desalination, and flexible electronics and robotics.
Flow capacitors and batteries are among the most promising technologies for future renewable energy storage demands. They allow a decoupling of power and energy density, making them particularly suitable for storing energy generated intermittently by wind and solar sources. These applications hold significant promise for addressing energy and environmental challenges. However, they are currently limited by the use of highly viscous sludges composed of spherical particles or heavy, unstable liquid metals.
The fluids developed in this project will overcome these limitations and provide new degrees of freedom for future sustainable applications of electrochemistry in flow systems.
