New cobalt-free high-voltage spinel cathode material with high areal capacity
Researchers from the University of California San Diego (UCSD) and the University of Texas at Austin, with colleagues at the US Army Research Laboratory and Lawrence Berkeley National Laboratory, have developed a thick cobalt-free high voltage spinel (LiNi0.5Mn1.5O4 (LNMO)) cathode material with high areal capacity. The paper on their work is published in the Journal of Power Sources. Advancing cathode materials with both high energy density and low cost have always been the main objective of battery material research. Developing cobalt-free cathode materials is one of the significant concepts to lower down the price of current LIBs. … It should be noted, the cost and sustainability of lithium-ion batteries are not only limited by the production of Co and Ni but also potentially limited by the lithium element itself. … The price of Co fluctuates significantly, with the inconspicuous fall of Ni price and continues growing of Li price. It is expected that with the large-scale popularization of electric vehicles and energy storage, the price and consumption rate of lithium resources will be even higher. Developing cathode material with less lithium and cost-effective elements such as Mn/Fe/Al is thus quite imperative. —Li et al. (a) Annual price of Li, Mn, Al, Fe, Ni and Co elements; (b) element mass ratios in five common cathode materials; (c) benchmark radar map for five widely used cathode materials. Li et al. High voltage spinel (LNMO), is one of the most promising candidates yet to be commercialized for novel cathode materials with high energy density, low cost, and improved safety. More importantly, the researchers note, it does not contain expensive cobalt or an excessive amount of lithium—making LNMO cost-effective and suitable for applications in the field of power batteries and large-scale energy storage. However, the material faces two primary obstacles: inferior electronic conductivity and fast capacity degradation in full cells due to the high operating voltage. By systematically addressing these limitations, we successfully develop a thick LNMO electrode with areal capacity loadings up to 3 mAh·cm−2. The optimized thick electrode is paired with a commercial graphite anode at both the coin cell and pouch cell level, achieving a full cell capacity retention as high as 72% and 78%, respectively, after 300 cycles. We attribute this superior cycling stability to careful optimizations of cell components and testing conditions, with a specific focus improving electronic conductivity and high voltage compatibility. These results suggest precise control of materials quality, electrode architecture and electrolyte optimization can soon support the development of a cobalt-free battery system based on a thick LNMO cathode (>4 mAh·cm2), which will eventually meet the needs of next-generation Li-ion batteries with reduced cost, improved safety, and assured sustainability. —Li et al. The University of Texas researchers, led by Arumugam Manthiram, have separately reported a new class of high-energy cathode anchored by high nickel content. ( Earlier post .) Resources

BEVERLY HILLS, Calif., June 29, 2018 /PRNewswire/ -- Attendees at the 2018 Summer Fancy Food Show are the first to get an in-person look at Oxigen's exciting brand evolution and overhaul to its drinkoxigen.com website. The changes provide a cleaner and more sophisticated look to the brand's scientifically proven oxygen-enhanced exercise recovery and lifestyle products. Oxigen™ water is oxygen-enhanced with 100 times more oxygen than regular water to replenish and restore brain, body and spirit. The highly stable, proprietary O4 oxygen molecule used to enhance Oxigen is scientifically proven to clear lactic acid twice as fast. If O2 is good for you, imagine what O4 can do. Oxigen water and shots are oxygen-enhanced using a proprietary, highly stable O4 oxygen molecule in liquid form. While already setting itself apart by offering proven and all-natural benefits of added oxygen, the brand refresh further enables Oxigen to stand out in a highly competitive global functional beverages category. "Oxigen has enjoyed steady and significant growth since our launch in 2015, driven by a highly experienced and passionate team dedicated to our long-term success," says Blair Bentham, Founder and CEO, Formula Four Beverages Inc, makers of Oxigen. "Refreshing our brand is about more than changing a logo or updating a tag line, it's also about sharing the incredible story of Oxigen in a way that resonates with consumers domestically and around the world." The company undertook both quantitative and qualitative research before finalizing its refresh, with the brand strategy lead by international branding, media and content agency SCS | Schiefer Chopshop, based out of Irvine, California. "Oxigen combines life's two most important elements: oxygen and water. When your body has access to more oxygen—thanks to the proprietary O4 oxygen molecule—it gives you faster recovery, increased stamina and improved focus. The message is that simple," says Bentham. Oxigen water, currently sold in a 20 fl. oz. 100% rPET bottle, is formulated to deliver 100 times more oxygen than regular water, while Oxigen shot is a 0.5 fl. oz. concentrated shot with another five times that amount. Ahead of the refresh, the company has gained a foothold with major retail partners across the U.S. and significantly expanded its distribution network to include grocery, natural, convenience, and the vending channel. Oxigen is ramping up its marketing efforts in key regions across the U.S. this summer, including sampling and guerilla marketing opportunities to coincide with tournament games involving German soccer champions FC Bayern, taking place in Philadelphia and Miami. Oxigen acts as the Official Functional Water + Recovery Tool of the world champion team. Oxigen's two products are distributed throughout the U.S., with the water available in approximately 8500 retail locations. The company is targeting 40,000 points of sale by the end of 2018. Its oxygen-enhanced water is also sold in Mexico and the Middle East. About Oxigen™

Because some A2BO4-based materials such as (Pr,La)2(Ni,Cu,Ga)O4+δ exhibit high oxide-ion conductivity, scientists at Tokyo Tech have been exploring new structure families of ABCO4-based materials as BaRInO4, where R represents a rare earth element. Here, A, B, and C are cations located at different crystallographic sites, and A, B, and C in ABCO4 correspond to A, A, and B, respectively, in A2BO4. Many researchers have investigated the optical, electrical, and magnetic properties of CaFe2O4-type materials, but the CaFe2O4-type pure oxide-ion conductors have not been reported yet. Therefore, Professor Masatomo Yashima and colleagues synthesized a new CaFe2O4-type material, strontium ytterbium indium oxide, SrYbInO4. They investigated its crystal structure from room temperature to 1273 K, its temperature and partial pressure dependence of electrical conductivity, and oxide-ion diffusion pathways. The occupancy factors are also carefully refined using not only conventional X-ray diffraction data but also time-of-flight (TOF) and angle-dispersive-type neutron and synchrotron X-ray diffraction data in order to obtain reliable results. They demonstrate a partial Yb/In occupational disorder in SrYbInO4 through careful analyses of occupancy factors. Prof. Yashima and colleagues have chosen the chemical composition SrYbInO4, because it contains no transition-metal cation, which leads to less electronic conduction. Moreover, SrYbInO4 was expected to have the CaFe2O4-type structure in the structure field map shown in Fig. 1. Ionic radii of Sr2+ and (Yb3+, In3+) are larger than those of Ca2+ and Fe3+, thus the SrYbInO4 is expected to have a lower activation energy for oxide-ion conductivity compared with CaFe2O4. Yellow isosurface of the BVE at 0.8 eV suggests that the oxide ion migrates in the b direction along the edge/surface of light blue purple octahedra BO6 [B = Yb0.574(2)In0.426(2)] and purple octahedra CO6 [C = In0.574(2)Yb0.426(2)] where the number in the parenthesis is the estimated standard deviation.

SrYbInO4 was synthesized by a solid-state reaction. SrYbInO4 was characterized through X-ray diffraction, chemical analysis, and thermogravimetric analysis. The band gap of SrYbInO4 was also estimated using UV-vis reflectance spectra, which suggested that SrYbInO4 is an electronic insulator. These results strongly suggested that SrYbInO4 was a pure oxide-ion conductor. Using neutron and synchrotron X-ray diffraction data and Rietveld method, Prof. Yashima and colleagues showed that SrYbInO4 is a single orthorhombic phase with Yb/In occupational disordering at the B and C sites, and no vacancies at the cation and oxygen sites. Bond valence sums and DFT-based structural optimization indicated the validity of the refined crystal structure of SrYbInO4. Therefore, the new material SrYbInO4 is the first example of pure oxide-ion conductors with a CaFe2O4-type structure. Further the temperature dependence of oxide-ion conductivity showed lower activation energy of SrYbInO4 (1.76 eV) than that of CaFe2O4 (3.3 eV), which was supported also by the bond valence-based energy calculations. The lower activation energy is attributable to the larger bottleneck size for oxide-ion migration due to the larger ionic radii of Sr2+ and (Yb3+, In3+) than those of Ca2+ and Fe3+, respectively. Prof. Yashima and colleagues claimed that the oxide ion conductivity of SrYbInO4 could be improved by doping, changing the degree of cation ordering and disordering, and using larger A, B, and C cations in the ABCO4-structure, which leads to further lowering the activation energy and higher oxide-ion conductivity. The findings of this study may open new pathways in the development of ABCO4-based ion conductors.
