Postdoctoral Researcher Position to work on New Generation of Redox Flow Batteries.

IMDEA Energy Institute is a María de Maeztu Center of Excellence whose objective is to develop R&D activities in the fields of renewable energies and clean energy technologies by establishing strong links with leading companies in the energy sector. (


IMDEA Energy is opening a Postdoctoral Position for the Electrochemical Processes Unit, looking for talented and motivated candidates to work on a next-generation of sustainable Redox Flow Battery (RFB), which relies on the use of solid boosters and organic molecules through redox-mediated processes.

Energy Storage Systems (ESSs) have become key elements for achieving a sustainable energy and transportation system. Among the EESs, different battery technologies hold great promises for enabling the necessary transition from fossil fuels to renewable sources. However state-of-the-art flow (All-Vanadium and Zinc – Br2) and static (Na-ion and Li-ion) battery technologies fail to satisfy all key performance indicators, e.g. sustainability, cycle life, recyclability, energy and power decoupling, cost or energy density.

In this context, the Electrochemical Processes Unit of IMDEA Energía is opening a Postdoctoral Scientist Position to work on Advanced Redox Flow Batteries. The selected Postdoctoral candidate will contribute to lay the foundations of a next generation battery technology named Mediated Redox Flow Batteries. This technology which will overcome critical limitations of state-of-the-art battery technologies exhibiting an excellent balance among these key performance indicators. The radically new vision of this novel battery technology relies on a combination of unconventional thermodynamically-driven concepts that will lead to a paradigm shift in energy storage. The proposed new battery technology relies on a flowing configuration system that:

i) possess the intrinsic benefits of flowing systems (energy conversion reactor separated from energy storage reservoir),

ii) boost the energy density by storing energy in solid materials confined in the external reservoirs, and

iii) guarantee the stability of the systems over long periods of time by using immiscible liquids.

The selected postdoctoral candidate will be involved in the MeBattery European Project ( and will be beneficiated of the complementary expertise of the highly qualified partners of MeBattery consortium (including 3 ERC awardees). The final prototype aims to demonstrate a long-life, safe and eco-friendly flow battery technology based on noncritical materials.
