TEESMAT - Open Innovation Test Bed for Electrochemical Energy Storage Materials

New TEESMAT Partners


New TEESMAT Partners

The TEESMAT partners are pleased to welcome HydraRedox and E-magy in the consortium. The two companies official joined the project on the 21st of September.

We are going to present you HydraRedox and E-magy profiles in the section below.


HydraRedox Iberia S.L. (HRI) is a Spanish SME based in Zaragoza. The company was formed in 2014 to develop and commercialize energy storage solutions based on a proprietary radically new approach to vanadium redox flow battery technology. HRI’s  systems are extremely flexible and modular and boast a set of unique characteristics that makes it the ideal partner for renewables –  technologically, environmentally, and commercially. The company continues to develop and improve its technology for performance and cost optimisation and adapt it to address new challenges and applications.

HRI’s team has decades of combined experience in electrochemistry (vanadium redox in particular) and is applying its research and manufacturing capabilities to the TESSMAT consortium as a Service User.

HRI is adding flow battery testing to TEESMAT’s portfolio of services by presenting a broad and varied range of needs and challenges which cover all aspects of vanadium redox flow technology. The emphasis is on improving and maintaining technical and commercial competitivenessof vanadium redox flow batteries through the selection and optimisation of key specialty materials for the electrochemical cells. In addition, characterisation techniques will be applied to new compositions of the vanadium electrolyte with the aim of reducing investment costs and improving performance. Electrochemical and chemical materials are to be tested for electrical, chemical, and thermal stability for properties characterisation and operando assessment.  

HRI is applying its experience in flow batteries to the validation of existing techniques to demonstrate TEESMAT’s technical capabilities beyond solid state batteries.  In addition, the company will contribute to the service and data management aspects and will support TEESMAT in data collection and analysis to assess and make recommendations for the commercialization of its services for the flow battery sector.


To preserve our planet for future generations, the world needs to make the transition from fossil fuels to renewable energy. Batteries play a key role in storing sustainably generated power. So the race is on to produce higher energy, faster charging and longer lasting batteries for all industries from portable consumer electronics and micro medical devices to automotive and stationary energy storage systems. Silicon – abundant as a natural resource and environmentally friendly – holds the promise of making this a reality; silicon anodes are the next leap forward in battery evolution. The biggest challenge facing the application of silicon-dominant anodes in Li-ion batteries, is silicon’s tendency to expand when charged. 

The unique, nano-porous silicon sponge material that E-magy has developed overcomes this challenge by containing that expansion within the nanopores themselves. Li-ion batteries with anodes made of 80% E-magy silicon hold 40% more energy than those made of graphite. It’s the low-cost, drop-in solution compatible with existing production lines that the EV industry needs – as currently verified by R&D managers of more than a dozen leading automotive and battery manufacturer brands.

E-magy is led by advanced materials specialists with over 20 years of silicon crystallisation experience and on a mission to empower clients with unique silicon solutions and know-how, bringing them winning battery performance. E-magy uses a proprietary process with standard industrial post-processing to manufacture nano-porous silicon and is currently scaling up to realise a fully commercial production line in 2023, for 300 tons or 2.5 GWh per year. Tests performed in cooperation with ZSW – the leading German institute for applied research in battery technology – have shown a negligible anode thickness variation of <5% after 100 cycles. The unique process is scalable and clean, at greatly reduced cost. E-magy silicon is effectively applied in coin and pouch cells today. EV batteries are next. Partnering with some of the world’s most renowned organisations E-magy is rapidly advancing, pushing battery innovation forward.
