Can't find a paper on the subject, but the UK Atomic Energy Authority (UKAEA) has a promo video which shows off (what they claim is) a proof of concept device. So the team seems to have some serious money and influence behind them:
Then since batteries are in demand, cheap ones doubly so, and ones that don't rely on rare Earth minerals from Chine triply so, they should have a wide market to tap into to make them profitable. Then also, as the UK is a NATO country, an invention like this could reasonably be argued to be a national security issue, which implies (very lucrative) government contracts.
