hours at most to convert 99% of LFP to FP in the case of the minimum theoretical reaction ratio of 1:2. 4) Sodium TS (Na2S2O3) completed the lithiation of FP into LFP. 5) The kinetics of the lithiation could be explained by a surface-reaction limited model. 6) The lithiation rate was first-order proportional to both lithium and thiosulfate concentrations, and an overall second order rate constant was around 0.03 min-1 M-2. 7) The maximum adsorption capacity was 46 mg-Li/g-solid, which is comparable with that of any other types of adsorbents except some manganese-based adsorbents with the capacity of 38–40 mg-Li/g-solid63–66. 8) The extractions of other ions such as sodium, potassium and magnesium from a brine solution were less than 4 mg/g-solid. In place of thiosulfate, other reducing agents have been studied by some researchers. Iodide (I-) is one of them. Kuss et al.67 successfully converted FP into LFP with lithium iodide in acetonitrile, which is an organic solvent. Intaranont tried to use the same reaction of iodide in aqueous solution as shown in Equation (2.17). The potential of I2/I- couple is from HSC database. (2.17) Since the overall reaction is thermodynamically unfavorable, the reaction was aided with the zinc- iodine reaction of Equation (2.18).24 I2 +Zn→ZnI2 (2.18) However, the author found that the reaction was incomplete although a high concentration of iodide was used and iodine was removed from aqueous phase to a solid phase of zinc iodide in - 52 - Cathodic:FePO4+Li+ +e− →LiFePO4 Anodic: 2I− →I2 +2e− Overall : 2FePO4 +2Li+ + 2I− → 2LiFePO4 + I2 E0 =0.40Vvs.SHE E0 =0.62Vvs.SHE E0 = −0.22 V vs.SHEPDF Image | LITHIUM EXTRACTION FROM BRINE using ion resin

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 | RSS | AMP |
