Figure 45. Electrochemical impedance spectroscopy (EIS) for anatase-TNTs at different 1M KOH (pH = ~14) and seawater (pH = ~8) electrolytes under irradiation at 0.7 V vs. RHE: (a) Nyquist plots and (b) the Bode plots. We used electrochemical impedance spectroscopy to study the charge transfer characteristics of the TNTs photoelectrodes. We compared Nyquist plots and Bode phase plots for TNTs in 1M KOH and seawater electrolytes under 1 sun illumination. The charge transfer resistance at the photoelectrode/electrolyte interface can be estimated from the semicircle diameters in Nyquist plots. TNTs exhibit small charge transfer resistance, demonstrating excellent PEC performances in seawater and 1M KOH. Typically, two characteristic frequency peaks can be observed in the Bode phase plots of the impedance spectra. The low-frequency peak in the range of 1 ~ 100 Hz reflects the electron transfer in the photoelectrode and charge reaction at the photoelectrode/electrolyte interface, and the high- frequency peak (in the kHz range) corresponds to the charge-transfer at the counter electrode. As confirmed in Figure 44, TNTs show only single peak in low frequency region, indicating a remarkable electron lifetime. Interestingly, TNTs in seawater has longer electron lifetime than that in 1M KOH. 75PDF Image | China solar seawater battery

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.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 turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
