Years ago, many of us on Vortex followed the unfolding story of EEStor. Another bummer.
The made amazing claims for Ultracapitors that were better than the best lithium batteries in every respect. Then they crashed and burned… although they are apparently still in business. Their BaTiO dielectric has achieved third-party certification of dielectric constant (K) of 16,000 at 500 volts. That should blow away Elon’s lithium design but would probably be best suited to work in tandem – the so-called Batt-Cap. The one below has K of 25,000,000,000 !!!! but … catch-22, that number is at 1 V. In theory but not in practice one could wire 500 of them in series, and beat the socks off EEStor, but… there are problems with that approach. I will save the details for another occasion. You may recognize the name of the author if you have followed the field of fractional hydrogen: Superdielectric Materials Composed of NaCl, H2O and Porous Alumina By Jonathan Phillips Prof. Physics Naval Postgraduate School Monterey, CA 93950 CONCLUSION- The most significant finding of the present study is empirical: a pH neutral aqueous solution of NaCl in a porous alumina constitutes a super dielectric material. Moreover, the dielectric constant was a function of salt concentration, reaching a maximum value, at nearly one volt, of greater than 2.5 1010 (25 billion), establishing that super dielectrics have dielectric constants orders of magnitude greater than any previously observed. This suggests that super dielectric materials, as per earlier suggestion, are a broad class of materials: porous, non-conductive materials saturated with ion-containing liquids.
