4.2 Experimental detail 4.2.1 Preparation of Pb-based anode Pb-O-C composites were prepared by high-energy mechanical milling. Lead oxide/super –P carbon (7:3 in weight ratio) was added to a stainless jar and sealed in glove box. PbO and Pb3O4 lead oxide (Sigma aldrich) were used (Table 7). The sealed jar was shaken in SPEX 8000M MILL GRINDER for 6 h to completely pulverize the particle and make composites. The Pb-O-C composites electrode consisted of 80 wt% of obtained powder, 10 wt% carbon black, and 10 wt% NMP-soluble binder (polyvinylidene fluoride PVDF, Solvay Solef 5130) laminated on a copper foil current collector and dried 75 ̊C under vacumme oven for 12 h. 4.2.2 Cell assembly and electrochemical tests Electrical testing was carried out using coin cell (2032 type) with 1.0 M NaPF6 in PC + 2 wt% FEC (Sigma aldrich) was used as electrolyte at the negative electrode, sodium metal (Sigma aldrich) anode and glass fiber (Whatman) as separator. The cells were assembled in a glove box under a high purity Ar atmosphere (oxygen and water < 1.0 ppm). Electrochemical performance tests were performed using an automatic galvanostatic charge/discharge unit, Maccor battery cycler, in the voltage range of 0.005 – 2 V Na at room temperature at a current density of 100 mA/g. 4.2.3 Characterizations X-ray diffraction (XRD) was performed with a D/Max, Rigaku apparatus equipped with a Cu-Kα X-ray source (λ =1.5406 Å ) and operando high energy x-ray diffraction (HEXRD) was performed in Advanced Photon Center (APS) at Argonne National Laboratory (wave length at 0.108 Å). The surface morphology was observed by scanning electron microscopy (SEM, JEOL JCM-6000 PLUS). 90PDF 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 (Standard Web Page)
