  • Patent number: 11165064
    Abstract: Systems, methods, and compositions are disclosed for a Li-substituted layered-tunneled O3/spinel Na(NixFeyMnz)O2 cathode material, Na0.87Li0.25Ni0.4Fe0.2Mn0.4O2+? (LS-NFM) for enhanced sodium ion storage and cycling stability. The LS-NFM electrode is prepared by adjusting the stoichiometric ratio of the Na ion over the sum of Li and transition metal ions below 1. The Rietveld refinement of XRD data indicates that the cathode is composed of 94% layered and 6% spinel components. When cycled at a high current density of 100 mA g?1, LS-NFM cathode exhibited a first-cycle Coulombic efficiency of 88% and reversible discharge capacity of 107 mAh g?1 after 50 cycles with the capacity retention of 95%.

  • Patent number: 9016286
    Abstract: This invention discloses a method for adding tobacco dust in production process of the papermaking tobacco sheet and its equipment. The tobacco dust is added in 5-30% weight at four process points such as the pipeline from the slurry stabilization box to the slurry flow box, the long-net of the papermaking machine, the position from the vacuum couch to the first press, and the coating position on the papermaking machine. This invention adopts a method for adding the tobacco dust in production process of papermaking tobacco sheet, which has well improved its physical performances including the filling capacity of the papermaking tobacco sheet and solved smoking problems of the papermaking tobacco sheet, such as worse inherent quality, heavy stemy note, insipid tobacco aroma and etc. In addition, this method has also offered a good way to well utilize tobacco dust resource in sizes of 2 mm-100 mesh, which is abnegated in cigarette production, to save resource and to reduce the cigarette cost.

  • Patent number: 8007637
    Abstract: This invention relates to a production process of tobacco sheet by papermaking. The technical arrangement of this invention are: (a). to immerge and to extract tobacco stem and leaf scrap respectively by water-soluble solvents to respectively obtain solid tobacco stem and solid leaf scrap, and tobacco stem extract and leaf scrap extract via solid/liquid separation; (b). to defibrilate solid tobacco stem and solid leaf scrap respectively, to mix the obtained tobacco stem fiber and leaf scrap fiber and combined with dust to prepare fiber base; (c). to wholly or partly abnegate the tobacco stem extract obtained by Step (a), and to evaporated and to concentrate other extracts that then are sprayed or immerged to coat the formed fiber base that is then dried, threshed and shaped. The tobacco sheet production process offered by this invention has improved the tobacco sheet's filling capacity and its sensory quality.
