Figure 66 shows that the charge-discharge voltage profiles of the seawater cell with a Na metal anode (cathode half-cell; top) and the 2032 half-cell with the Pb-O-C composite electrode (anode half- cell; bottom) at the second cycle. In the case of the cathode half-cell (Na meal | seawater), charging was done at a rate of ~ 3.8 V vs Na+/Na while discharging was performed at ~ 2.9 V vs Na+/Na at a current rate density of 0.025 mA/cm2. The anode half-cell (Na meal | Pb-O-C composite #1) exhibited a sodiation potential of ~ 0.5 V vs. Na+/Na and a desodiation potential of ~ 1.5 V vs. Na+/Na. Based on the voltage profiles of both half-cells, a simulated voltage profile for the seawater full-cell with the Pb- O-C composite #1 anode is plotted in Figure 67. The average charge and discharge voltages for the full- cell were estimated to be ~2.7 V and ~1.7 V, respectively at the second cycle. Figure 68 shows that the voltage profiles of the full-cell, cycled with a capacity cut-off at 300 mAh/gcomposite at charging and a voltage cut-off at 0.005 V at discharging. The discharge capacity in the first cycle was about 180 mAh/gcomposite, while the discharge capacity increased to over 225 mAh/gcomposite. Although the cycle stability to date are good, the cycle stability of the full-cell should be further observed. Figure 68.

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.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 turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
