<i>&quot;The test results from the new polymers suggest that extremely high energy density supercapacitors could be constructed in the very new future.&quot;</i> Not &quot;We have a demo model working&quot;. More on the actual chemistry, from 2017.[1] Seems they announced this before, in June 2017.<p>Even if this doesn&#x27;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:&#x2F;&#x2F;chemical-materials.elsevier.com&#x2F;new-materials-applications&#x2F;ultracapacity-polymeric-supercapacitors-viable-alternatives-batteries&#x2F;" rel="nofollow">https:&#x2F;&#x2F;chemical-materials.elsevier.com&#x2F;new-materials-applic...</a>

The 2018 version of this is <a href="https:&#x2F;&#x2F;www.surrey.ac.uk&#x2F;mediacentre&#x2F;press&#x2F;2018&#x2F;alternative-traditional-batteries-moves-step-closer-reality-after-exciting" rel="nofollow">https:&#x2F;&#x2F;www.surrey.ac.uk&#x2F;mediacentre&#x2F;press&#x2F;2018&#x2F;alternative-...</a><p>I&#x27;m not sure why the 2016 release was posted instead.

They claim 4F &#x2F; cm² between smooth surfaces, which seems impossibly high. Even if the dielectric is only 5 Å thick, that corresponds to a dielectric constant of 2.2e6. The highest dielectric constants materials I know of are around 2e4.

Anyone have a link to the actual paper? Some polymers are known to have extremely high dielectric constants.
