Calculation of the theoretical energy density of saltwater battery In the case of 5 M saltwater, the theoretical potential of the following redox reactions in the cathode side is calculated to be 3.43 V vs. Na+/Na according to the Nernst equation. Na (s) + 1β2H2O (l) + 1β4O2 (g) β NaOH (aq); E0=3.43 V vs. Na+/Na (pH=7) (S1) The theoretical gravimetric energy density was calculated using the following equation πΈπππ£ β π(5π πππΆπ) Theoretical energy density (mass) = ππππππ + ππππ‘hπππ = 368 Wh kg-1 (S2) The theoretical redox potential Erev is 3.43 V and Q is the quantity of electrical charge for 5 mole electrons generated from 1 L NaCl aqueous solution at 5 M ( π = 96485 πΆ/πππ Γ 5 ππππ/πΏ Γ 1 hπ 3600 π ππ). The mass of 1L saltwater is derived from its density (Ο5M, saltwater = 1.241 g mL-1) (ref. S3). Oxygen is assumed to be completely dissolved in the saltwater, and its mass is regarded as 1β4 of 5 mole according to reaction (S1) (ref. S4). Since Na can be fully provided from the saltwater during charging, the mass of the anode is not considered in this calculation. Therefore, the total mass of the anode and cathode is 1.241 kg, resulting in a theoretical energy density of 368 Wh kg-1. Likewise, for a battery with 6 M saltwater, the theoretical energy density is calculated to be 423 Wh kg-1, based on the theoretical redox potential (3.42 V vs. Na+/Na) and density (Ο6M, saltwater = 1.295 g mL-1).PDF Image | Saltwater as the energy source for batteries

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)
