8 B. J. WILSON analytical study solves the electrostatic problem for a system of parallel plates at differ- ent potentials. This solution leads to a determination of leakage currents and from these leakage currents the net battery terminal voltage. Taken from experimental results, Fig. 8 ahows the effect in fine scale of barrier length on a three-cell series batteries. At this level the leakage tendency is relatively small, but 1-inch extensions will produce about 4% gain in voltage. Figure 9 shows the comparative effects of end barriers at the 1.5, 3.0, 4.0, and 6.0 volt levels. The increasing severity of leakage with voltage level is apparent. 15 ,0 _ _ _ _is Fig, 8 - Effect of end baxrtrsat the 1.5-volt level. The specimen size is 2 by 4 inches.

Operation at the 1.5-volt level takes on added significance from the results above in that it is the least demanding on barrier length, which, of course, augurs well for con.- pactness. This gain is to be added to that for the attendant converter, which at the 1.5-% level can operate efficiently and with low-cost transistors. The use of larger barriers results in a relatively lesser size penalty as the power level and concomitant electrode dimensions are increased. As power is increased at a given voltage, the barrier extension length remains unchanged for a desired barrier effect, since it deals with what are essen- tially end effecis or external leakages.

Product and Development Focus for Salgenx
Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our flow battery manufacturing.CONTACT TEL: 608-238-6001 Email: greg@salgenx.com (Standard Web Page)
