Figure 35. Candidates for solar seawater battery photo-anodes and energy diagram for theoretically needed photocharging potential compared with Heat treatment Carbon felt (HCF) as a cathode current collector. Figure 35 shows several candidates that can be used as photoanode. Existing seawater battery cell uses HCF current collector as a cathode, the theoretical charging voltage is ~ 3.48 V. When TNTs photoanode is used, the theoretical photocharging voltage is ~ 2.05 V (Vphotocharge = ECB – ENa+/Na). In this experimental, TNTs was used as photoanode, but various photoelectrodes such as ZnO, WO3, and CdS could be applied to solar seawater battery system.111-130 In this work, we designed an optimized single device to test the solar seawater battery system with a photoelectrochemical cell by a using anatase-TiO2 nanotube arrays (TNTs) photoelectrode. Compared to heated carbon felt (HCF), which is used as a cathode current collector in seawater batteries,40 the use of TNTs photoanode resulted in a ~29% reduction in the charging voltage. Also, it was found that charging/discharging was possible through only TNTs photoanode and the voltage efficiency could be increased by dividing the photocharge part and discharge part. In the future, various photoelectrodes in addition to TNTs photoanode can be applied to such a solar seawater battery system. 62PDF 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 |
