When Will Electric Vehicles Overcome the Battery Barrier?

Posted July 06, 2011 6:00 AM

More work needs to be done to overcome the performance limitations associated with the EV's on-board rechargeable lithium-ion battery. A report in Power Electronics Technology gives an overview of research into new electrolytes and rechargeable chemistries that may lead to batteries with improved capacity. Technology Review details a semi-solid flow battery combining the energy density of solid cells with the scalability of flow batteries. Slurries of high-energy-density lithium storage compounds and nanoscale conductor particles are pumped through the device. The result may be cheaper electric vehicle batteries providing energy densities an order of magnitude greater than available options. Another article with video describes the next-generation lithium-ion battery design philosophy pursued by Ann Arbor, MI-based Sakti3. Company founder Ann Marie Sastry explains how lightweight solid state batteries are being developed with reduced parasitic mass that undermines energy density. With these and other research projects ongoing, how strong are the near-term prospects for cheaper, high-performing EV energy sources?

I'd say very strong. One more article.

From what I'm reading, another major hurdle in switching over to electric vehicles, besides the technology itself, is the availability of raw materials to make the batteries on a large scale.

I think LENR technology will give rise to the hybrid LENR electric vehicles.

Brillouin Energy Corp is developing this technology now. As far as LENR is concerned the typical 3 points of disbelief are and addressed as follows.

  1. Over coming the coulomb barrier
    1. LENR is a weak interaction and only involves the accumulation of low energy neutrons.
  2. No fast neutrons.
    1. This reaction is due to the accumulation of cold neutrons and Beta decay. Similar to the S process in solar nuclear synthesis which is responsible for the valley of stability in the Chart of Nuclides.
  3. No Gamma rays.
    1. The 4H system is formed well below 1eV and does not change parity or spill with the Beta decay event. With no spin parity change, electric dipole radiation of gamma rays is forbidden and the energy is transferred to the lattice as phonons. (Julian Schwinger)

Based on the Brillouin Energy Corp.(BEC) hypothesis and supporting experiments at Brillouin Energy, LENR is driven by a weak interaction. Any material with a unit cell or molecule able to include hydrogen nuclei and obtain or exceed a Molecular Hamiltonian of 782KeV due to the superposition of phonons (dT < fSec) has the potential to run a Controlled Electron Capture Reaction (CECR) process, providing the system has conduction or valence band electrons available for capture. Peter Hagelstein showed that this is possible starting on page 24 of his article in RLE Progress Report 145. The electron capture event provides a natural reduction in energy of the system instantly removing 782KeV of energy from the unit cell nanoparticle or molecule. That energy represents the removal of a proton from the bounding Coulombic box, an electron, and conversion of energy to mass.

A detailed paper / Hypothesis is available at the links below. It stays within the current (2011) standard model of physics. This reaction involves several steps that require some knowledge in several different disciplines. The first link provides the background necessary. I strongly recommend LISTENing to the power point at
http://www.brilloui nenergy.com/ BE25Tec.PPS at least once before reading the full hypothesis at
http://www.brillouinenergy.com/BrillouinEnergyHypo thesis.pdf

BEC is not the first mover in this field but our technology will grab the market as our technology comes on line. people should google Rossi Swedish skeptic society for information on the first mover in this field

In Rossi's reactor the neutrons accumulate in the Ni lattice / nanoparticles, The xms spectra I saw did show some accumulation of some Zn in the system as well. Because Cu is less reactive than the Ni due to the electron shell structure Cu tends to be the main end result of Ni transmutation through the accumulation of neutrons (Google S process). I strongly suspect and the hypothesis predicts that if someone were to use a good Helium detector they would also find 4He coming out of a Rossi system.

Looks as though Lithium Sulphur may be a way forward

THE ONLY WAY TO OVERCOME THIS DELIMA IS TO FOWARD THE TECHNOLGY ,THE MAIN PROBLEM I SEE IS THE DESERTATION ON THE ION INGULFED THIS HAS TO CHANGE IF THERE IS GOING TO BE A BETTER BATTERY. ED MARTINEZ M.L.D. MOLECULAR LINEAR DYNAMICS.

Yes, research is positive. And come back in - maybe 10 years - when you know ANYTHING about the new chemistry, like efficiency, # of load cycles, deep discharge, load balancing, LIFE EXPECTANCY, cooling / heating issues.

If you care to know, what it takes, read up on NASA nicad research. Looong time for research.

In the meantime, sonny, where do you suppose the power is coming from to charge the beastie? I hope, not FM.
