position may result in Jahn-Teller distortion [72], [87]. This distortion leads the crystal to lower its energy which is favorable. In lithium manganese oxide, this type of distortion may cause tiny distractions in crystal lattice and result in a loss of capacity of the adsorbent. 3.3.6 Selectivity experiments The selectivity experiments were conducted by a feed solution which consists of equal concentration of lithium, sodium, potassium and magnesium ions at pH:10. The results and conditions of the experiments were tabulated in Table 3.30. Table 3.30 Selectivity of lithium manganese oxides with respect to Na, K and Mg.

The relatively high selectivity for Li+ can be explained by the ion-sieve effect of the spinel lattice with a three-dimensional (1×3) tunnel, suitable in size for fixing Li+ in cubic phase MnO2 ion sieves obtained from LiMnO precursors, yet other metal ions can only adsorb on the adsorbent surface sites because of their large ionic radii, similar to the cases of the MnO2 ion-sieves in other studies [77], [87]. Moreover the tapotactic insertion-desertion mechanism of Li+ ions in the crystal lattice does not let other ions to take place of the lithium ions. This ability of the adsorbent makes it unique for selective lithium separation operations compared to other candidate chemicals. 94PDF 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 | RSS | AMP |
