In adsorption method, lithium manganese oxides (LiMnO) were synthesized with solid-solid and hydrothermal reaction procedures under different temperature and Li/Mn ratios. The performance of the adsorbent with the highest capacity value was characterized at different pH, lithium and foreign ion (Na, K, Mg) concentrations. It was found out that, LiMnO adsorbent has a capacity value of 22.8 mg Li/g adsorbent at pH:10.2 in dilute lithium chloride solutions with a very high selectivity towards foreign ions such as sodium, potassium and magnesium. In order to employ LiMnO adsorbents in an adsorption column, micron sized particles were impregnated into millimeter sized beads made of poly(styrene-maleic anhydride-glycidyl methacrylate) (PSMA) by precipitation method. PSMA has been utilized in bead formation process for the first time in this study and gave superior results compared to previous analogs in terms of its swelling and self-crosslinking ability. The column performance filled with PSMA-LiMnO beads were evaluated with artificial brine, concentrated brine taken from Çamaltı Salina (İzmir) and boron clay extract taken from Bigadiç. The lithium concentration in brines was increased from 0.43 ppm to 1675.6 ppm while reducing the foreign ion concentrations significantly in adsorption column. The post treatment of the column product with LiMnO resulted in a solution with 3200 ppm Li. That concentration is above the required minimum concentration for Li2CO3 production, which is the raw material for lithium battery industry. The adsorption method, utilizing new PSMA-LiMnO beads in a column was found as a promising candidate for practical use in conventional separation of lithium from brines.

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)
