8170 General Demonstration Figure 3.General Demonstration of sea water battery Clorine ion and water molecule are two important substance in sea water that can be oxidized at the positive electrode side, shown in the above figure and as reactions below [Eqs. (2) and (3)] 2H2O(l)->O2(g) +4H+(aq)+ 4e- (2) 2Cl- (aq)-> Cl2(g) + 2e- (3) Therefore, two possible overall reactions can be considered during the charging process [Eqs. (4) and (5)] 2 NaCl(aq) + H2O(l) ->2Na(s) + 2HCl(aq) + 1⁄2 O2(g) (4) 2 NaCl(aq)-> 2Na(s) + Cl2(g) (5) In both chemical processes, gas evolve at the positive electrode, even though the voltages for the generation of O2 and Cl2 are slightly different (0.14 V). Although O2 evolution is thermodynamically preferable to Cl2 development, the measured charge voltage of the saltwater[3] may be linked to both Cl2 and O2 gas evolution reactions. The ratio of Cl2 evolution to O2 evolution is higher in general because the O2 evolution reaction has a higher overpotential when saltwater [NaCl (aq)] undergoes an electrolytic process (Figure 4). Sodium ions created by the Na metal at the negative electrode moved into the saltwater through the solid electrolyte during battery discharge. According to the half-cell reaction [Eq. (6)], the following chemical reaction happened at the negative electrode. : 2.71V = Na->Na+ + e- E0 (6) Two hypothetical electrochemical processes which involves H2O and O2 which is dissolved in it [Eqs. (7) and (8)] can be studied at the positive electrode: E0 = 0.40 V = 2H2O + O2 + 4e3>4OH- (7)PDF Image | Electric lantern using sea water

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 | RSS | AMP |
