DIONBATENER: Dual Na+/anion ion batteries for sustainable renewable energy storage

Ignacio Cameán Martínez (Gijón, 1979), holds a degree (2004) and a PhD (2011) in Chemistry from the University of Oviedo.

He developed his thesis in the National Coal Institute (INCAR) of CSIC in Asturias with an FPI grant that included a stay at the University of Cordoba (Spain).

His research is based on the preparation of carbon materials for electric battery electrodes with the aim of consolidating renewable energies and electric vehicles.

He has 25 publications and 2 patents, has directed a thesis and 2 master’s theses and is co-founder of the company Nanographite.

He was awarded the Energy and Environment Research Grant by the Iberdrola Foundation in 2016 and selected by the French MOPGA programme for a 3-month stay at CNRS (Orleans, 2018).

He was a ComFuturo researcher from 2018 to 2021 in the research line of the programme “Sustainable energy systems“, when he developed his ComFuturo project “Dual Na+ ion/anion batteries for sustainable renewable energy storage” at INCAR.

Project Summary

There is currently a global consensus on the need to reduce greenhouse gas emissions, which requires a transition from the current energy model, based mainly on the use of fossil fuels, to one in which the use of renewable sources will predominate. However, renewable energy sources are discontinuous in nature, so their efficient use and management require the use of energy storage systems (ESSs) that can be connected to the electricity distribution networks. Among the different systems, electric batteries are one of the most interesting alternatives. Specifically, lithium-ion batteries (Li-ion batteries) are considered the most suitable for this application in terms of energy, power, safety and service life. However, the cost of energy supplied by BILs is in the range €480-2,000/kW h, with the estimated cost-effective value for EDCs being less than €200/kW h. This high cost is due to the fact that both the cathode and the electrolyte of a BIL are made up of lithium compounds whose price has increased considerably, mainly as a consequence of the growing demand for portable electronic devices and electric vehicles. Therefore, it is necessary to develop other types of alternative electric batteries for EDCs that avoid the use of lithium in order to reduce the cost of the energy supplied while maintaining performance.

Application: This project aims to develop innovative electric batteries for the sustainable storage of renewable energy using carbon materials. These batteries will minimise the environmental impact associated with preparation, use and subsequent recycling. The project offers an alternative to lithium-ion batteries, which are ideal in terms of energy storage, safety and service life, but have become more expensive due to the growing demand for portable devices and electric vehicles.
