for a sustainable world

Passion for technology

Our battery technology fleece aims to take electric energy storage to the next level. We strive to accelerate the transformation from a fossil fuel-based to a CO2-free economy and to contribute significantly to the availability of sustainable energy, when and where it is needed.

Our Technology

Today’s complex packaging of battery cells, based on thin layers and stacking technology, is dramatically resource-wasting and causes batteries to underperform and to be less safe than they could be.
We are launching the transition from 2D foil current collectors, used in today’s lithium-ion-batteries, to fleece current collectors. Our technology fleece provides a disruptive innovation for state-of-the-art and emerging battery technologies. batene fleece™ increases energy density of lithium-ion-batteries and enables extreme fast charging.

batene fleece™ makes battery cells thicker, faster, safer, and resource-efficient

Icon of a thick battery represented by thick lines

Higher battery performance thanks to electrodes with up to millimeters thickness which push the active material weight fraction to 90% of the cell.

Icon of a fast charging battery represented by a stopwatch

Much faster charging and more powerful batteries due to enhanced Li-ion mobility and reduced internal electrical resistance.

Icon of a safe battery represented by a warning triangle and a check mark

Dramatically enhanced mechanical stability and reduced internal electrical resistance eliminate unfavourable hotspots in heat generation, as well as electrical and mechanical stress.

Resource- efficient

Significantly extended battery lifetime and up to 30% less material costs per kWh due to millimeter thick electrodes. The batene fleece™, as the current collector and the active material, are highly elastic and adapt to volume changes during charging and discharging. This prevents premature ageing of the battery.

Our Purpose

Global energy demand will continue to grow rapidly, thus the transition to sustainable energy sources plays an important role on the road to a climate-friendly society.
Electrical energy, generated by photovoltaic and wind power plants, is the most efficient form of energy. For wireless utilisation, batteries are indispensable, a requirement for electric vehicles, smartphones, power tools, medical equipment and technical safety devices.

More powerful batteries with longer range and life are essential for the transition from the present fossil fuel-powered to an all-electric technology. To meet future energy needs, battery production must be massively scaled-up and available to everyone, anytime and everywhere, in a resource-saving way. Our goal is to develop this new generation of batteries, to be a key contributor to energy mobility and availability, and to shape the decarbonised energy future.

Our story

After eight years of research at the Max Planck Society, Batene GmbH was founded in March 2022 by a team of experienced scientists. The Max Planck Society has developed an IP-protected core technology based on fleece and exclusively licensed it to Batene. The Max Planck Society is a shareholder of Batene.

Batene is being financially and technically backed by a board of investors and visionaries who care about our future economic, ecological and social responsibility:

Ocean Zero LLC is a co-lead backer investing in innovative young companies that can accelerate the decarbonisation of marine transport. Ocean Zero was founded by Chris Anderson, the head of TED Conferences LLC, and Stephen Petranek, a science and finance journalist who was editor-in-chief of The Washington Post Magazine, Discover Magazine, and Breakthrough Technology Alert, as well as science editor of Life Magazine.

Christer von der Burg is a co-lead investor. He is founder of Hanshan Tang bookshop, specialising in books on East Asia. Today, he is active in building up what is now the second largest collection of antique Chinese woodblock prints in the world.

Gustav Hasselskog is the founder and CEO of Candela Technology. Candela has re-invented marine transportation by developing electric passenger and leisure crafts using hydrofoil technology.

Batene celebrates the grand opening of its cutting-edge laboratories with partners and supporters from politics, science and business

Batene has unveiled its state-of-the-art battery labs in the historic Neckarspinnerei in Wendlingen.
In her speech, Minister of Economic Affairs Dr. Nicole Hoffmeister-Kraut emphasized the transformative role batteries can play in reducing our dependence on fossil fuels, reaffirming the pivotal position of Baden-Württemberg as the premier hub for battery technology.

The research and development laboratories are an essential cornerstone in our journey towards advancing battery technology and fulfilling our responsibility for a sustainable future.

Batene develops more powerful and resource-saving batteries

Batene GmbH was founded after several years of research at the Max Planck Society. Joachim Spatz, Director at the Max Planck Institute for Medical Research, and his team have developed an IP-protected core technology for innovative batteries based on metallic fleece and exclusively licensed it to Batene GmbH.

Batene embraces sustainability from the very beginning

Batene is located at the Neckar spinning mill complex (Neckarspinnerei), a landmarked site of a former water-powered textile company near Stuttgart, Germany. Already in 1861, when the buildings were constructed, a strong emphasis was placed on merging work life and home life. Currently the historic industrial buildings in the complex are converted into a future-proof, mixed-use urban neighbourhood which combines working, manufacturing and living with a CO2-neutral energy and mobility concept.

We are excited about the strong and committed partnership with the developer HOS Group, the State Baden-Württemberg and Region Stuttgart, and hence the opportunity to “go green” right from the start.
