Polymer synthesis Synthesis of poly(TEG-alkoxybithiophene) p(gT2) In a dried 5.0 mL microwave vial, 79.4mg of (3,3'- bisalkoxy(TEG)-[2,2'-bithiophene]-5,5'- diyl)bis(trimethylstannane) (97.3 μmol) and 63.1mg of 5,5'-dibromo-3,3'- bisalkoxy(TEG)-2,2'- bithiophene (97.3 μmol) were dissolved in 3.0 mL of anhydrous, degassed DMF. Pd2(dba)3 (1.78 mg, 1.95 μmol) and P(o-tol)3 (2.37 mg, 7.78 μmol) were added and the vial was sealed and heated to 100 °C for 16 h. After the polymerization has finished, the end-capping procedure was carried out. Then, the reaction mixture was cooled to room temperature and precipitated in methanol. A blue solid was formed which was filtered into a glass fibre-thimble and Soxhlet extraction was carried out with methanol, ethyl acetate, acetone, hexane, and chloroform. The polymer dissolved in hot chloroform. Finally, the polymer was dissolved in a minimum amount of chloroform and precipitated in methanol. The collect solid was filtered and dried under high vacuum. A blue solid was obtained with a yield of 74 % (70 mg, 71.6 μmol). GPC (DMF, 50 °C) Mn = 56 kDa, Mw = 306 kDa.1H NMR (CDCl3, 400 MHz) δ: 6.96 (br s, 2 H), 4.35 (br s, 4 H), 4.01 – 3.92 (m, 4 H), 3.81 – 3.79 (m, 4 H), 3.72 – 3.70 (m, 4 H), 3.66 – 3.63 (m, 4 H), 3.53 – 3.50 (m, 4 H), 3.34 (s, 6 H) ppm. 27PDF Image | salt water battery with high stability

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 |
