Research in Battery Materials and Technologies

The research group of Battery Materials and Technologies, led by associate professor Pekka Peljo, is developing next generation stationary energy storage technologies, mostly based on redox flow batteries.  We are an experimental group focusing on discovery of new materials, aided by our collaborators utilizing advanced computational tools, and developing novel testing methods to accelerate materials testing.

Our research areas:

  • Stationary energy storage in redox flow batteries
  • Understanding charge transfer at interfaces
  • Energy storage and conversion 

Research projects

Development and in operando characterization of solid redox boosters for high energy density redox flow batteries

This project funded by Academy of Finland (2018–2023) focuses on demonstrating the concept of solid boosters for flow batteries, as well as developing tools to characterize charge transfer with the solid boosters.

Bioinspired organic redox flow batteries for sustainable and safe energy storage

The BioFlow-project (2019–2023) develops safe and sustainable flow batteries for large-scale energy storage, based on bio-inspired organic molecules, in collaboration with Prof. Petri Pihko, University of Jyväskylä. This project is funded by Academy of Finland.

CompBat: Computer aided desing for next generation flow batteries

We are coordinating this EU-project. CompBat (2020–2023) will focus on developing tools for discovery of new prospective candidates for next generation flow batteries, based on machine learning assisted high-throughput screening. We are also developing computational tools for simulating batteries at the cell and stack level.

Partners: Dr. Imre Papai (Természettudományi Kutatóközpont, Hungary), Prof. Kari Laasonen (Aalto University, Finland), Prof. Daniel Brandell (Uppsala Universitet, Sweden), Prof. Umberto Desideri (Universitá di Pisa, Italy), Prof. Keith Stevenson (Skolkova Institute of Science and Technology, Russia) and Prof. Petri Pihko (University of Jyväskylä, Finland).

Bioinspired, biphasic and bipolar flow batteries with boosters for sustainable large-scale energy storage

The EU-funded Bi3BoostFlowBat project (2021–2025) will develop cost-efficient batteries featuring low cost, optimal redox potential and high solubility. The project plans to achieve this by introducing several strategies, including utilization of solid boosters, bio-inspired materials, biphasic systems and bipolar membranes, to find the best compounds that will lead to the desired results.

Jenny and Antti Wihuri Foundation homing grant

Jenny and Antti Wihuri Foundation awarded us a homing grant in 2019 to help to improve the research infrastructure in our lab. We will use this grant to improve our flow battery testing systems, and to build a scanning electrochemical microscope.

Digital drive for revolutionizing materials discovery for the next generation energy storage

This project (2020–2023) will develop digital technology enablers based on advanced computational modelling and machine learning to screen prospective molecular candidates to realize scalable, inexpensive and sustainable energy storage based on redox flow batteries, focusing on metal compexes. It is funded by the Future makers program of Technology Industries of Finland Centennial Foundation and Jane and Aatos Erkko Foundation.

The collaborators include Prof. Kari Laasonen (Aalto University) and Prof. Petri Pihko (University of Jyväskylä).

Photoproduction of hydrogen in biphasic systems with electron donor recycling

We are starting again some work on photoproduction of hydrogen at liquid-liquid interfaces! We will collaborate with Prof. Marcin Opallo (Institute of Physical Chemistry, Polish Academy of Sciences), and Prof. Hubert Girault (EPFL), with our part focusing on development of photoelectrochemical flow cells for such systems. This project (2020–2023) is funded from the Solar-Driven Chemistry network initiated by the German Research Foundation - Deutsche Forschungsgemeinschaft (DFG). From Finland the funding organization is Academy of Finland.
