Crystals 2018, 8, 425 6 of 12 the following electrochemical impedance spectra measurement (EIS) analysis, may lead to a lower initial coulomb efficiency of pristine LNCM than the Cl and Br co-doped LNCM. Figure 4. Initial charge and discharge capacities of the synthesized LiNi1/3Co1/3Mn1/3O2 compounds at 0.1~3C: (a) Pristine LNCM; (b) Cl&Br co-doped LNCM. The cycle performances of the synthesized LiNi1/3Co1/3Mn1/3O2 compounds at different rates are shown in Figure 5. It demonstrates that the Cl and Br co-doped LNCM has an excellent cycle stability, and it can restore to the initial capacity of 0.1C after two cycles at 0.1C, 10 cycles at 0.2C, 0.5C, 1C, 3C, and then back to 0.2C, respectively, while the capacities of the pristine LNCM decrease rapidly. The cyclic curves of the pristine LNCM and the Cl and Br co-doped LNCM at 1C for 50 cycles show that the initial and 50th discharge capacities, and the capacity retention of the Cl and Br co-doped LNCM are 173.3 mAh g−1, 161.5 mAh g−1, and 93.2% respectively, which are obviously higher than the pristine LNCM (152.6 mAh g−1, 123.7 mAh g−1, and 81.1% for comparison). We presume that the good cycle performance of the Cl and Br co-doped LNCM compounds benefits from the enhanced structure stability after doping and the Mn4+ in the surface layer of the LiNi1/3Co1/3Mn1/3O2 compounds, which can avoid the dissolution and the John-Teller effect of Mn3+. Also, the observed differences in rate capability should rather be attributed to the different morphology, which is a side effect of doping, or rather to the surface doping on an atomic level, probably by the change of electronic structure or diffusion.PDF Image | Enhanced High Voltage Performance of Chlorine Bromine

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 |
