The invention discloses a flame-proof electrolyte and its lithium battery for secondary lithium battery, which is characterized by the following: adopting one or more phosphosubester (such as methyl acid phosphate dimethyl ester, ethyl phosphate diethyl ester and its derivant) as pure solvent or solvent component; reducing the price of electrolyte with incombustibility, low toxicity and high conductivity; improving the combusting safety effectively.

The invention discloses a production method of a chemosynthetic water-soluble fertilizer, the chemosynthetic water-soluble fertilizer prepared through the production method of the chemosynthetic water-soluble fertilizer and application of the chemosynthetic water-soluble fertilizer. According to the method, production is performed by taking industrial diammonium hydrogen phosphate and / or monopotassium phosphate, nitrogenous fertilizer and potash fertilizer as main raw materials through hydrogen bonding, acid regulating by adding alkaline and the like. The production method is little in investment, few in production procedures, short in production cycle and low in production cost. The chemosynthetic water-soluble fertilizer is appropriate in acidity, capable of achieving the good crystalline state, stable and uniform in composition, not prone to be hardened and damped, capable of being fully dissolved in water, easy to absorb and convert, high in fertilizer utilization rate, significant in synergistic effect and suitable for being applied to acidic or meta-acidic soil and facility greenhouses.

The invention discloses resilient magnetic carbon foam and a preparation method thereof. The magnetic carbon foam material is prepared from melamine foam through ultrasonic cleaning, magnetic metal ion solution soaking and carbonization pyrolysis in an argon atmosphere. The resilient magnetic carbon foam is composed of a melamine foam carbonized porous framework, magnetic metal nanoparticles and carbon nanotubes formed by catalyzing the magnetic metal nanoparticles, and the magnetic metal nanoparticles are coated with the generated carbon nanotubes and evenly distributed on the surface of themelamine foam framework. The magnetic carbon foam has the advantages of magnetism, electrical conductivity, low density, high specific surface area, high resilience and the like; the resilient magnetic carbon foam has good application prospects in the fields of electromagnetic shielding and wave absorption, magnetic sensors, oil absorption, electrochemical catalysis, battery electrodes, supercapacitors and the like, and especially in the aspect of electromagnetic wave absorption, broadband strong absorption of electromagnetic waves can be achieved under the condition of a low addition amount.

The conductive polymer dispersion liquid of the present invention contains a conductive composite, a silicate having two or more silicon atoms, an aromatic compound, and an organic solvent, and the conductive composite includes a π-conjugated conductive polymer and a polymer. Anion, the above-mentioned aromatic compound is selected from compounds in which two or more hydrogen atoms of the aromatic ring are replaced by hydroxyl groups, compounds in which two or more hydrogen atoms in the aromatic ring are replaced by carbonyl groups, and one or more hydrogen atoms in the aromatic ring One or more compounds among compounds substituted with a hydroxyl group and one or more hydrogen atoms substituted with a carbonyl group.

The present invention relates to water purifying scale remover, and is especially artificially water purifying scale remover with tourmaline as main material. The water purifying scale remover is prepared with tourmaline 60-75 wt% and Yiwangshi stone 25-40 wt%, and through crushing into nano level fineness, mixing and packing. It is added into water in the amount of 1-5 % to eliminate scale. The said minerals are sintered into pellet and set inside container for filtering water. The prepared water purifying scale remover may be used widely in industrial and civil water treatment, especially in boiler descaling.
