Additionally, the change in chemical structure will affect increase or decrease lithium extraction/selectivity is the IL anion because this is direc energy bonding as this energy will be related to the charge density in the bonding acceptors involved in lithium bonding. Additionally, the change in chemical structure will aff atoms that are present in the anion, specifically in the P=O group; in this group, the charge energy bonding as this energy will be related to the charge density in the bonding acc density will be affected by the radicals present in the vicinity of the bonding.

The introduction of carbon molecules bonding the phosphorus atom in the IL anion, the better the lithium extraction. This is d bonded to phosphorus reduces both the bonding interaction due to its electron donating to the electron withdrawing effect of oxygen, which provides a higher density charge character and the negative density charge area.

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 |
