Neoteric solvents, electrolytes and hierarchical materials inspired by nature.
The Bioinspired Materials Group is a research group of the Instituto de Ciencia de Materiales de Madrid, an institute of the Consejo Superior de Investigaciones Científicas (CSIC) (Spanish National Research Council). As best lessons are provided by nature, the BMG’s main scientific interest has been the use of biomimetic and green chemistry for the preparation of hierarchically organized materials. Since 2006, the BMG has demonstrated the performance of these materials in the fields of energy – as electrodes in energy-related devices – and environmental sustainability – as CO2 adsorbents.
More recently, the BMG is exploring the use of deep eutectic solvents (DESs) in green chemistry and environmental sciences. BMG´s interest in green chemistry resides in the significant relevance that is gaining in materials science. It is widely accepted that for scaling up and with increasing environmental status and regulatory pressure focusing on solvents, much attention must be paid to the use of green chemistry alternatives. Applications of DESs and aqueous DES dilutions – e.g. CO2 absorption, metal and liquid-liquid extraction for pollutant remediation and battery recycling are a being studied by the BMG group. Within this line, we have also focused on eutectic, crowded and semi-concentrated electrolytes. They are easily prepared, inexpensive and furthermore, they can be designed to be sustainable. These electrolytes can boost the energy density in redox flow batteries, as they can achieve high concentrations while maintaining wide electrochemical windows. Considering both the rate capability and energy efficiency of devices, eutectic electrolytes must exhibit considerable ionic conductivity (>10-3 Scm-1) and ionic diffusion, but also low viscosities for mass transport and flowing processes. Electrolyte engineering can modify the physicochemical properties of electrolytes, as well as control the cations solvation shell at the electrode-electrolyte interface, which can provide an effective way to passivate adverse interfacial reactions. All these properties are critical for a new generation of safe, efficient and stable batteries and supercapacitors.
