First charge (delithiation) curves of LixFePO4 electrodes obtained from the reaction product of 0.375 M FePO4 mixed with 0.75 M Li2SO4 and 1.5 M Na2SO3 with different reaction times. Specific current: 17 mA g-1 (C-rate of C/10). Figure 4 shows examples of the galvanostatic cycling done with electrodes made with the LixFePO4 obtained from the chemical insertion driven by Na2S2O3 or Na2SO3 after 24 hours of reaction time. The electrochemical data in figure 4a shows that full lithiation of FePO4 was obtained with both reducing agents after 24 hours of reaction time, since the first lithium extraction capacities were the same as in the as received LiFePO4. Further cycling of the samples is shown in figure 4b, showing good cycling stability, in good agreement with the measurements with the as received LiFePO4. The good electrochemical performance of the samples obtained after the lithium sequestration reaction indicates that the present approach could also be applied for the direct recycling of battery electrodes.41,42 For example, the addition of a reducing agent could be used to recover fully lithiated LiFePO4 from a battery containing used LixFePO4 electrodes that could have inhomogeneities in the lithium content E (V vs Li+/Li) 0 20 40 60 80 100 120 140 160 Capacity (mA h g-1) 13PDF 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 | RSS | AMP |
