Batteries 2022, 8, 157 6 of 26 tions, it was observed that the Na metal deposit exhibited a needle‐like shape after depo‐ sition in 1 M NaPF6‐DME electrolyte. After the introduction of Li+ additives, the Na metal showed a smooth morphology deposition, which was extremely disparaged from the nee‐ dle‐like Na dendrites. This result validated the resisted Na dendritic growth due to the electrostatic shield effect and enhanced electrolyte stability after introducing Li+ additives. Figure 2.

From the aforementioned discussion, it is found that the increase in inorganic con‐ stituents, especially NaF could improve the stability of the SEI layer, leading to the elec‐ trochemical enchantment performance for NMBs. Based on this result, the F‐containing ingredients were also utilized as electrolyte additives in NMBs. Fang et al. utilized SbF3 as an electrolyte additive in 4 M NaFSI‐DME‐based electrolytes for NMBs and found that the SbF3 additive could build a bilayer SEI layer [72]. One layer was constituted by the Na‐Sb alloy layer from the Sb‐ion electrolyte. Another layer was derived from the F ion of the SbF3 additive, resulting in the formation of the NaF‐rich SEI layer on the Na metal surface, as shown in Figure 3a. Due to these features of the bilayer SEI layer, the Na||Na symmetric battery presented enhanced stable cycling of 1000 h at the current density ofPDF Image | Electrolyte Engineering for Sodium Metal Batteries

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)
