theoretical studies have shown that the insertion of protons or hydrogen into FePO4 is negligible.52,53 The ICP results can also be used to calculate the lithium purity in the solid, which equals the uptake of lithium by the solid divided by the sum of the uptakes of all cations. With Na2SO3, the lithium purity in the solid equals 94% and 96% for brines 1 and 2, whereas for Na2S2O3, it is 90% and 96%. Thus, it is concluded that very high lithium purities in the solid can be achieved by this method: the values of lithium purity compare well with the lithium purity in the recovery solution reported in previous studies (see table 1). Further improvements in lithium purity could be achieved via the optimization of the process and materials. For instance, the LiFePO4 used in this work has been optimized for battery performance in terms of particle size, carbon coating etc., but the properties required are different for lithium production/recycling applications.

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)
