The invention relates to a multi-stage core and shell structure multi-element material precursor used for an anode material of a lithium ion battery. The molecular formula of the multi-stage core and shell structure multi-element material precursor is (1-x)Li[NiaMnbCo1-a-b][OH]2 x [NimConM1-m-n][OH]2, wherein M=Mn, Al, Mg andTi, the x is larger than or equal to 0.2 and smaller than or equal to 0.9, the a is larger than or equal to 1 / 3, the b is smaller than or equal to 1 / 2, the m is larger than or equal to 0.6 and smaller than 1, and the n is larger than or equal to 0 and smaller than or equal to 0.3. A core and shell multi-layered compound structure is adopted, a core of the core and shell multi-layered compound structure is made of a high-nickel-based and high-specific-capacity multi-element material, a shell of the core and shell multi-layered compound structure is made of a high-safety material with the identical nickel and manganese molar content, wherein the high-safety material contains a small quantity of cobalt or does not contain the cobalt, a space between the core and the shell is made of a multi-layered material and is configured according to proportions different from those of the shell and proportions of the core, the proportions of core materials in the multi-layered material from inside to outside are gradually reduced while the proportions of shell materials in the multi-layered material from inside to outside are gradually increased, and accordingly the multi-stage core and shell structure is formed. The multi-stage core and shell structure multi-element material precursor not only has a high specific capacity performance of the core materials, but also has characteristics of high circulatory stability and safety of the shell materials, and is low in large-scale manufacturing cost. The cost is not increased as compared with a homogeneous multi-element material. Besides, repeatability is high, batch stability is good, and the multi-stage core and shell structure multi-element material precursor meets requirements of large-scale commercial application.

The invention provides radix acanthopanacis senticosi and vitis amurensis wine and a preparation method thereof and belongs to the field of wine brewing. The preparation method comprises the following steps: mixing vitis amurensis and radix acanthopanacis senticosi according to the mass ratio of (3 to 4) to 1 and crushing to obtain a first fixed material; mixing white granulated sugar, potassium metabisulfite, active dry yeast and the first fixed material to obtain a second mixed material; pre-fermenting the second mixed material for 12 to 18 days at 20 DEG C to 25 DEG C; after separating peel pomace, obtaining first fermented liquid; fermenting the first fermented liquid for 35 to 45 days at 18 DEG C to 22 DEG C; separating fruit pulp to obtain second fermented liquid and aging. The radix acanthopanacis senticosi and vitis amurensis wine prepared by the method has a good health-care effect and high quality; the mouthfeel, flavor, color and luster and aroma of the radix acanthopanacis senticosi and vitis amurensis wine are relatively excellent.
