Batteries 2022, 8, 173 4 of 11 Figure 2. FE- SEM micrographs of electrolyte membranes with various LiTFSI contents of (a) LiTFSI- 40%, (b) LiTFSI-50%, (c) LiTFSI-60%, and (d) LiTFSI-70%. According to the results of the XRD, the crystallinity of the PVDF-HFP polymer de- creased as the LiTFSI lithium salt increased. The DSC was employed to investigate the crystallization behavior of the hybrid electrolytes. An empty aluminum ingot and the samples were heated and cooled with 5 °C/min. The material’s fundamental thermal char- acteristics, such as melting point (Tm), enthalpy change (ΔH), and crystallization temper- ature (Tc), were determined. Figure 3 shows the DSC spectra of electrolyte membranes with various LiTFSI contents. The kinetic energy of the molecules increased as the tem- perature rose, causing the structure of the polymer to change from crystalline to amor- phous. An endothermic peak appeared as the polymer transformed from crystalline to molten and was determined as the endothermic peak’s starting point, which was the melt- ing point of the polymer (Tm). The Tm of the LiTFSI-40%, LiTFSI-50%, LiTFSI-60%, and LiTFSI-70% was 123.2 °C, 110.2 °C, 108.1 °C, and 110.5 °C, respectively. Figure 3. DSC spectra of electrolyte membranes with various LiTFSI content for (a) LiTFSI-40%, (b) LiTFSI-50%, (c) LiTFSI-60%, and (d) LiTFSI-70%. One of material characteristic requirements for solid electrolytes is acceptable me- chanical strength to prevent puncture by the lithium metal dendrite. The mechanical properties of the hybrid electrolyte membranes as indicated by a tensile machine are shown in Figure 4 and Table 1. The tensile strength of the hybrid electrolyte membrane decreased as the content of LiTFSI lithium salt increased. The tensile strength values of the LiTFSI-40%, LiTFSI-50%, LiTFSI-60%, and LiTFSI-70% were 4.42 MPa, 3.34 MPa, 2.06PDF Image | Lithium Salt Concentration on Materials

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 (Standard Web Page)
