Lucas123 writes: John Goodenough, the University of Texas researcher who this week demonstrated new battery cells that are safer and have at least three times as much energy density as today's standard Li-on batteries, responded to skeptics who said the technology described in research published in a peer-reviewed journal, appear to defy the laws of thermodynamics. In an article published Monday by Quartz , various energy experts took exception to Goodenough's claims, even calling them "unbelievable." Goodenough is also co-inventor of the original lithium-ion battery. In an email to Computerworld, Goodenough said "any new discovery invites strong skepticism." In this case, the skeptical scientists wondered how it is possible to strip lithium from the anode and plate it on a cathode current collector to obtain a battery voltage since the voltage is the difference in the chemical potentials (Fermi energies) between the two metallic electrodes,. "The answer is that if the lithium plated on the cathode current collector is thin enough for its reaction with the current collector to have its Fermi energy lowered to that of the current collector, the Fermi energy of the lithium anode is higher than that of the thin lithium plated on the cathode current collector," Goodenough said.
