<i>"The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very new future."</i> Not "We have a demo model working". More on the actual chemistry, from 2017.[1] Seems they announced this before, in June 2017.<p>Even if this doesn't turn into a big energy storage thing, maybe they can replace ordinary electrolytic capacitors. Least reliable component in electronics.<p>[1] <a href="https://chemical-materials.elsevier.com/new-materials-applications/ultracapacity-polymeric-supercapacitors-viable-alternatives-batteries/" rel="nofollow">https://chemical-materials.elsevier.com/new-materials-applic...</a>
