The invention discloses a silicon dioxide composite anode material for a lithium ion battery, as well as a preparation method and an application of the silicon dioxide composite anode material. The silicon dioxide composite anode material is prepared from the components of silicon dioxide powder and a conductive carbon layer with the surface of the silicon dioxide powder is uniformly and densely coated. With the adoption of the silicon dioxide composite anode material, the original component structure of an SiO material system is kept, so that the lower volume effect is ensured; the silicon dioxide dense carbon layer coating structure is successfully realized by adopting the technologies of mixing kneading, sheet rolling, press forming and the like, and thus the first coulombic efficiency of the silicon dioxide composite anode material is remarkably increased, and can reach a theoretical value being larger than 77 percent, and the cycle performance and the conductive characteristic are also remarkably improved, so that the silicon dioxide composite anode material is suitable for being charged and discharged with the large rate and can be applied to the power market.

The invention provides a high-strength efficient cement-based light transmission material and a preparation method thereof, belonging to the field of novel building materials. The high-strength efficient cement-based light transmission material is prepared from the following materials in parts by weight: 100 parts of light calcined magnesia, 65-135 parts of magnesium chloride aqueous solution, 0-60 parts of admixture, 10-80 parts of light transmission fibers, 0.1-1 part of defoamer, 1-10 parts of polyvinyl alcohol micro powder, 0.1-1 part of phosphoric acid and 0.5-3 parts of ferrous sulfate. The preparation method has the advantage of preparing the high-strength efficient cement-based light transmission material based on the characteristics such as high strength, high abrasion resistance, high glossiness, low basicity and the like of the magnesium oxychloride cement. The novel light transmission material not only has good light transmittance performance to the visible light, but also reduces the chemical corrosion action of the cement base body to the light transmission fibers while ensuring the original mechanical properties of the cement base, as well as has the characteristics such as high strength, high durability, high ornamental value and the like.

The invention provides a manufacturing method of a temperature-uniforming plate, which comprises the steps of providing a flat first bottom plate with a first bottom surface, wherein the first bottom surface includes at least one cavity region; etching the first bottom plate to form at least two first grooves, and forming a non-etched first post between every two first grooves within the same cavity region; forming a first capillary structure on the surfaces of the first grooves and the first post; filling a working fluid in the first grooves; covering the adhesive on a first surface outside the cavity region; providing a second bottom plate with a second bottom surface, second grooves and a second post; laminating the first bottom plate and the second bottom plate together in the vacuum state to form a closed cavity by the first grooves and the second grooves; and curing the adhesive to obtain the temperature-uniforming plate. The invention also relates to a temperature-uniforming plate manufactured according to the above method.
