CONCLUSIONS Na2SO3 is shown to be an advantageous reducing reagent to drive the selective sequestration of lithium from natural brines into a FePO4 host battery material, for applications in an alternative and sustainable method of lithium production, as illustrated in figure 1. The kinetics of the lithium sequestration reaction are found to be fast, since full lithiation is achieved in one hour in 1.5 M Na2SO3 solutions. The selectivity of the lithium sequestration reaction is found to be outstanding, since in natural brine solutions containing up to 60-fold excess of sodium, 6-fold excess of magnesium and 3-fold excess of potassium, the amount of lithium inserted per gram of solid absorbant is ca. 45 mg/g whereas the uptakes of sodium, potassium and magnesium were below 0.9, 0.3 and 1.9 mg/g, respectively. Consequently, the kinetics and selectivity of the lithium sequestration reactions are comparable to those previously reported using Na2S2O3 as reducing agent.30 However, Na2SO3 has advantages in terms of lower cost, reaction stoichiometry that involves less consumption of reagent, non- toxicity and formation of an innocuous reaction product (Na2SO4).

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)
