Abstract: The invention relates to a method for preparing high-stability liquid blueberry anthocyanins, belonging to the field of food processing. A method for preparing high-stability liquid blueberry anthocyanins comprises the following process steps: adding graphene oxide and chitosan to an MES buffer solution at room temperature, mixing homogeneously and adding EDC and NHS sequentially, reacting to obtain a first solution; adding dry blueberry anthocyanin powder in the first solution, adjusting pH to 4.5 to 5.0 and mixing homogeneously to obtain a second solution, and treating the second solution at 350 to 420 MPa and 2 to 4° C. to obtain the product. The method for increasing the stability of blueberry anthocyanins provided by the present invention uses dry blueberry anthocyanin powder as a raw material and adds graphene oxide combined with chitosan compound as an anthocyanin stabilizer, thereby increasing the stability of blueberry anthocyanins during processing and production.

Abstract: A nonaqueous cell employing an anode such as lithium or lithium alloy, a liquid lithium salt nonaqueous electrolyte, a thermal shutdown separator and a cathode comprising a homogeneous hybrid mixture of carbon fluoride and manganese dioxide, said carbon fluoride or poly-carbon fluoride being represented by the formula (CFx) wherein 0.5?x?1.2 and contained in said mixture in a ratio by weight of about 5 to 99%, preferably about 5 to 50% and said manganese dioxide is heat treated electrolytic manganese dioxide represented by EMD or MnO2. The CFx—MnO2 hybrid cathode cells yield high capacity with high discharge rate and excellent low-temperature performance without voltage delay. The cells are characterized by two significant plateaus in their discharge profiles, the first contributed by MnO2 and the second by CFx.

Abstract: The present invention provides mesostructural metal oxide materials that can be employed in lithium ion rechargeable batteries as intercalation electrodes. The mesostructural metal oxide materials of the present invention maintain their structural integrity during intercalation, are reversible and exhibit increased electrochemical capacity. The use of such mesostructural metal oxides in rechargeable batteries is also described herein.
