Figure 3. Schematic illustration of the commonly used Li-ion battery based on a graphite anode and a LiCoO2 cathode.16 Among various electrochemical energy storage systems (e.g., lithium-ion, metal-air,23, 24 redox- flow batteries25-27), the LIBs show good electrochemical performance, such as high voltage with low redox potential (E ̊(Li+/Li)= -3.04V vs. SHE) and high energy density (~300 Wh/kg), long cyclability (≥2,000 times) and competitive energy cost (250–400 $ kWh-1)11, 28, 29. Because of these various advantages, LIBs are being used in a wide variety of areas, from ESSs to electrical vehicles (EVs) and portable devices (Figure 4). However, their long-term sustainable use may be limited because of the steeply rising prices of lithium, cobalt-containing raw materials and anode materials due to the increasing demand for LIBs in electric vehicles and large-scale ESSs (Figure 5). Also, the scarcity of lithium and cobalt resources significantly limits future ESS applications. Therefore, in order to solve the problem of price in such cathodes, recent researches have focused on reducing the cobalt ratio in the cathode or developing cobalt-free cathode materials.30-33 We approach different ways and would like to introduce a new battery system that uses natural seawater as its cathode, which does not rely on expensive lithium and cobalt materials. 15PDF Image | China solar seawater battery

Product and Development Focus for Salgenx
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 flow battery manufacturing.CONTACT TEL: 608-238-6001 Email: greg@salgenx.com (Standard Web Page)
