Figure 24. The problem of seawater corrosion. (a) Rusted stainless steel seawater coin-cell. (b) Teflon coated seawater coin-cell cap. (c) Polypropylene seawater coin-cell cap through injection molding method. Figure 24 (a) shows that corrosion problems have occurred in seawater due to the use of stainless steel which is used as a lithium ion battery coin-cell parts. In order to solve the corrosion problem, the surface of the cap was coated with teflon. When tested at a current rate of 0.5 mA/cm2, it was confirmed that charge/discharge was working at first time, but discharge did not proceed after ~40 hours. However, the cap that was in the polypropylene injection molding had no problem of charge/discharge process, and showed good cycle stability. So we decided to use the PP injection cap as cell parts through various trial and error. 42PDF 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 | RSS | AMP |
