These results coincide with the XRD data given in the literature [74] in which lithium at tetrahedral sites, manganese (III) and manganese (IV) at octahedral sites of a face centered cubic crystal system with 8.21 Å lattice constant. The XRD pattern of adsorbents having Li/Mn ratio different than 1 also gives similar pattern and it was found that, the molar ratio changes of Li/Mn does not affect the cyrstal structure significantly. In that manner adsorbents having Li/Mn ratio higher than 1 can give higher lithium content in the adsorbent and increase the capacity of lithium uptake. Unfortunately, in that case the stability of the adsorbent was found insufficient which was indicated by the blurred solutions due to dissolved manganese ions during adsorption process. The adsorbents synthesized at 650 and 750 oC give almost the same peaks in pattern. However peaks have high amount of noise and red colored impurities in crucible were observed after the synthesis. At temperatures 450 and 550 oC, the synthesis of manganese oxides give almost the same peaks. However peaks for 550 oC have less amount of noise. It is concluded that both temperatures are suitable for synthesis. In terms of lower energy consumption, 450 oC was used in the final adsorbents. The XRD pattern for the adsorbents synthesized at different temperature and molar ratios are given in APPENDIX B. 63PDF Image | 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)
