lithium ion transport properties and may end up blocking access to the inorganic lithium adsorbent. Inorganic ion sieves, such as HMO, have well-known high lithium uptake capacity, while the lithium-imprinted polymer binds Li+ and enhances its concentration at the HMO-polymer interface, improving the lithium uptake kinetics. Preparation and Characterization of Nanostructured LMO Nanostructured lithium manganese oxide (LMO) was prepared via hydrothermal synthesis. First, manganese dioxide (MnO2) is prepared from equimolar amounts of manganese nitrate tetrahydrate [Mn(NO3)2•4H2O] and sodium persulfate (Na2S2O8) dissolved in deionized water. The aqueous solution is transferred into a stainless-steel autoclave and heated for 12 hours at 248°F (120°C). The resulting black solid is filtered, washed thoroughly with deionized water, and dried overnight at 212°F (100°C). Next, the manganese oxide powder is thoroughly mixed with a suitable amount of 0.5 molar (M) lithium nitrate [LiNO3 (aq)] in the desired Li/Mn molar ratio. This mixture is then heated in the oven for 12 hours at 212°F (100°C) to remove water. Finally, the resulting mixture is calcined in a furnace at 842°F (450°C) for six hours to obtain the LMO nanopowder. The nanostructure of the resulting LMO powder is confirmed by scanning electron microscope (SEM) analysis. The photographs in Figure 1 show the needle- like nanostructure of the LMO that has a width of 100 nm and length less than 1 micron.

Source: SRI International Nanostructured HMO was prepared by stirring the LMO powder in a solution of 0.5 M HCl for a predetermined period of time to exchange the Li+ in the inorganic sorbent with H+. The resulting HMO was then filtered and thoroughly washed with water. The lithium uptake capacity of the nanostructured HMO was initially evaluated in a batch test by contacting the inorganic sorbent with a solution containing Li 360 mg/L, Na 15000 mg/L and K 9000 mg/L at 122°F (50°C) for 30 minutes. 11PDF Image | Selective Recovery of Lithium from Geothermal 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 | RSS | AMP |
