for 5 minutes) was repeated three times to obtain a homogeneous mixture. Subsequently, the resultant slurry was hand coated on an aluminum foil (Advent Research Materials, thickness = 0.125 mm, 99%) with a K-bar to a wet thickness of 200 μm. Prior to the coating, the aluminum foil was roughened with a P1200 sandpaper to improve adhesion. The electrodes were dried in a vacuum oven at 80 oC overnight and then, punched (precision punch, Nogami) with a 11 mm diameter die and calendaring to 10 tonnes (Specac). The active material mass loading was ≈ 3-4 mg cm-2. The electrochemical tests were performed in PFA Swagellok® type cells, previously dried at 80 oC overnight. The cells were assembled in an argon glove box (≤ 0.1 ppm H2O; ≤ 0.1 ppm O2), using the LixFePO4 electrodes as working electrodes and a lithium foil (Rockwood Lithium, 100 μm thickness, cut in 12 mm diameter discs) as both counter and reference electrode. The electrolyte was 150 μL of 1.0 M lithium hexafluorophosphate solution (LiPF6) in ethylene carbonate (EC) and dimethyl carbonate DMC with a volume ratio EC/DMC =1/1 (LP57, PuriEL). Two glass fibers (Whatman®, grade GF-F, 12 mm diameter) were used as separators. Aluminium current collectors were used for the LixFePO4 electrodes, whereas copper collectors were used on the lithium side. LixFePO4 electrodes and GF-F separators were dried under vacuum at 120 oC for 48 hours in a Büchi tube oven before being introduced in the glovebox. The cells were placed in a Memmert climatic chamber set to 25 °C and electrochemical measurements were done with a VMP2 multichannel potentiostat (BioLogic). Galvanostatic cycling with potential limitations (GCPL) between 2.7 and 4.1 V vs Li+/Li were performed at a C-rate of C/10 corresponding to a specific current (normalized by the mass of LixFePO4 active material) of 17 mAh g-1. 9PDF Image | Novel method of lithium production 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)
