5.1.4 Preparation H+ type λ-MnO2 λ-MnO2, which was supplied from Professor Yoshizuka, was Li+ typeλ-MnO2 because of unstability of H+ type λ-MnO2. According to his paper, the H+ type λ-MnO2 should be prepared from the Li+ type λ-MnO2 immediately before adsorption experiment of Li. Therefore, desorption behavior of Li+ from the Li+ type λ-MnO2 was examined to accurately determine the preparation condition of the H+ type λ-MnO2 from Li+ type λ-MnO2. According to a literature, one gram of the Li+ type λ-MnO2 was added in 100 cm3 of 1 mol dm-3 HCl. Figure 7 shows the desorption behavior of Li+ from the Li+ type λ-MnO2. After 10 min, most of the Li+ desorbed from the Li+ type λ-MnO2. The reaction can be represented as follows. This is the ion exchange reaction between Li+ and H+. Fig. 7.

One gram of the H+ type λ-MnO2 was introduced in the LiCl solution whose pH was about 10. According to Yonezu et al., the exchange rate of H+ to Li+ relatively faster in alkaline condition than in acidic condition. It can be deduced that OH- ion in bulk solution may pull H+ in the H+ type λ-MnO2 to form H2O. Li+ may transfer from the bulk solution to the empty site in the H+ type λ-MnO2. Figure 8 shows the adsorption behavior of Li+ by the H+ type λ-MnO2 under alkaline condition. Until 20 min, most of the Li+ was effectively adsorbed.

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)
