Crystals 2018, 8, 425 3 of 12 ratio) electrolyte. Lithium metal foil was used as the counter electrode during the electrochemical measurements. All of the cells were assembled in an argon-filled glove box. The charge–discharge tests were carried out using a Land BT2001A automatic battery test system. The charge–discharge tests were completed in the voltage range of 2.5–4.6 V. AC impedance measurements were carried out with the scanning range of 1 mHz to 100 kHz using a CHI660B electrochemical workstation system (CH Instrument, Shanghai, China). All of the tests were performed at room temperature. 3. Results and Discussions The SEM images of the precursor and the synthesized LiNi1/3Co1/3Mn1/3O2 compounds are illustrated in Figure 1. As can be observed from Figure 1a,b, the spherical Ni1/3Co1/3Mn1/3(OH)2 precursor compounds consist of flake-shaped primary particles, with an average diameter of ~10 μm. The pristine and halogen Cl and Br co-doped LNCM compounds keep the spherical morphology and consist of spherical-like or polygon primary particles, with an average diameter bigger than 10 μm, as shown in Figure 1c–f. The average primary particle diameter of the Cl and Br co-doped LNCM (~1.5 μm) is larger than that of the pristine LNCM (~1 μm). Cl and Br substitution would contribute to the growth of the primary particles of the LiNi1/3Co1/3Mn1/3O2 compound, which is consistent with the foregoing research on the fluorine-doped spinel LiMn2O4 [26]. With Cl and Br co-doping, the size of the primary particle becomes bigger, and the space between the primary particles increases, as shown in Figure 1f, which may allow the electrolyte solution to penetrate into the surface of these primary particles quickly.

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 |
