A New Battery Tech for Long-Duration Energy Storage

The start-up Unbound Potential has developed a new battery technology for long-duration energy storage – and received a grant of one million euros for it. By opting for immiscible electrolytes, they eliminated the need for an ion-exchange membrane, paving the way for a battery that offers a more efficient, affordable, and sustainable way to store renewable energy for long periods of time.

    00:00:00 we're trying to rely more on sustainable energy sources like wind and solar energy and these are intermittent it means that they generate power at times where it might not be needed and they might not generate sufficient power at times of high demand meaning that for example imagine a city like Berlin or Paris people wake up in the morning at 6:00 a.m. after a couple of days with a

    00:00:21 little wind and maybe a cloudy day and still there needs to be some massive battery system providing power for that and that's why we're talking about large scale or long duration energy storage which really requires a novel type of battery technology which is simply not there yet so I decided to start a company and build a new type of flow battery that takes advantage of cool

    00:00:42 things happening at liquid liquid interfaces we are going to exploit organic sustainable chemistry for membraneless Redux for batteries and this is the main challenge which we are right now tackling the battery will be made of two IM missible uh liquids one that represented uh here like water and and oil and these two liquids don't uh mix with each other and that's the key

    00:01:05 intuition uh behind the um reduxx flow battery now we can remove the typical membrane and we can uh reshape the interface between the these two liquids and that's where the magic happens we are developing a type of battery that's very scalable because of our um physics inside the cell not having a membrane we're able to do that cheaper and more efficiently than other flow barri

    00:01:29 systems current flow Battery Technology relies on vadium which is still material that's mined and which is scarce and expensive so we think it has quite some negative impact on the environment still that's why we rely on materials which can produce be produced in every country that's actually using our system and which are also fully recyclable from a technological point of view when talking

    00:01:50 to establish whe battery companies for example we' experienced that there's still a lot of skepticism how this can work and how it can scale and we think the current situation that there is this huge technology Gap uh we need some way to store energy but no one knows how shows that um the conventional way of approaching things doesn't really um help us in providing the solutions we

    00:02:12 need so I think being a little crazy and trying radically new stuff and building a battery a way that it's never been built before is um just the right way to go about it yeah
