, ; . : , Fig. 14 - Inert-cathode/IVg-anode sea -water cell depicting the electrode reactions and the principal charge-carrying mechanism in the electrolyte In view of the kinetics of the electrode reaction under load condition, no attempt is made to treat voltage conditions. Obviously this av~lable potential from Mg ionization serves both to supply energy to the load and bring about the electrolysis at the cathode. The sense of cell incremental or component potentials are apparent from the current directions, the nature of the Mg/H 2 0 interface as a source, and the role of the load, polarization, and Sel~eeclterocltyrsoilsytaes,equivalent or actual resistive loads. The magnitudes are best evaluated by measurement, the voltage-current characteristics yielding sufficient information for power-source calculations. Effect of Cathode-Surface Treatmentoand Texture Since the cathode sobstrate is steel, Its catalytic properties are enhanced by a Pd plating. But prior tothis, Niplate is first laid down, on top of which the Pd isplated. The results of these studies show that the role of the Ni plate is primarily one of rust Inhibiting during preuse storage or standby. This is brought out in Fig. 1•, where a slight diminution in perforraance is observed in the presence of Ni from that of Pd alone. The effect of a Ni-only plating is also shown in FIg. 15 for comparative purposes. The effective area enhancement of the cathode Is made apparent also in Fig. 15, where perforated or expanded metal exhibits a gain over the plain sheet. The screen shows a further gain. A complete comparative quantitative behavior for cathodes with these types of texturing has not been fully explored. Figure 16 shows how mesh size affects screen all other factorsSpbeirnfgorcmonasntacnet., Although the figure shows continued performance gain with increase in mesh fineness, this performance gain does not continue indefinitely. Ob the one extreme, increasingly finer mesh would approach an embossed solid plate in surface equivalence, whereas on the other extreme, a coarse mesh would eventually approach a diminishing area condition. A finer mesh m.,.y result in some performance gain as indicated but introduces battery fabrication p~roblems due to lack of rigidit. A larger self-supporting mesh may be worth some tradeoff In power performance. Coarser mesh may also contribute to better electrolyte circulation worthy of further power performance tradeoff. - @2 12 B. 3.

The diagram also indicates Mg(OH)2 formation both from direct reaction of Mg++ with OH-, particularly as a local anode rectlon, and from reaction of intermediary products NaOH and MgCl 2.

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)
