Crystals 2018, 8, 425 10 of 12 Figure 8. Electrochemical impedance spectra of the synthesized LiNi1/3Co1/3Mn1/3O2 electrodes after different cycles: (a) Pristine LNCM; (b) Cl&Br co-doped LNCM. 4. Conclusions A Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 compound was synthesized by the molten salt method. It was characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), galvanostatic charge–discharge measurements and electrochemical impedance spectra measurement (EIS). SEM results show that the pristine and halogen co-doped LiNi1/3Co1/3Mn1/3O2 compounds keep the spherical morphology consisting with spherical-like or polygon primary particles. Cl and Br substitution would contribute to the growth of the primary particles. The XRD results demonstrate that the LiNi1/3Co1/3Mn1/3O2 compound has the typical hexagonal layered structure, and no impurity phase is detected. XPS results indicated that the surface oxidation state of the compound is improved with Cl and Br substitution. The Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 compound exhibits both an improved rate capacity and cycle stability at a high voltage (4.6 V) compared with the pristine LiNi1/3Co1/3Mn1/3O2. The initial discharge capacities of Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 are 208.9 mAh g−1, 200.6 mAh g−1, 188.2 mAh g−1, 173.3 mAh g−1, and 157.1 mAh g−1 at the corresponding rates of 0.1C, 0.2C, 0.5C, 1C, and 3C, respectively. The capacity retention after 50 cycles at 1C is increased from 81.1% to 93.2% after doping. The better contact between the electroactive particles of the electrode and the smaller resistance would enhance the electric conductivity of the Cl and Br co-doped LiNi1/3Co1/3Mn1/3O2 cathode.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 |
