Metal salt-free sealing agent for aluminum alloy anodic oxide film

The invention provides a metal salt-free sealing agent for an aluminum alloy anodic oxide film, belonging to the technical field of aluminum alloy anodic oxide film post treatment. The sealing agent of the invention is prepared by water solution composed of 1.0-10g/L of a hydration accelerator, 0.01-2g/L of a wetting agent, 0.01-3g/L of an ash inhibitor and 1-15g/L of a pH buffering agent, wherein the pH of workpiece fluid is 5.5-6.5, the operating temperature is 70-90 DEG C, and the sealing speed is 1.0-2.0min/um. The metal salt-free sealing agent creatively adopts organic compounds which are easily subject to biodegradation, does not contain any metal ions of nickel, cobalt, magnesium, calcium, lithium and the like as well as fluorinions, and obtains satisfactory sealing effect of the nano-pores of the aluminum alloy anodic oxide film by virtue of the scientific and coordinated component formula of the water solution; the aluminum alloy anodic oxide film obtained by seal treatment through the sealing agent has the advantages of good corrosion resistance, capability of meeting the requirements of GB 14952.1-94, good light-protection and color-protection properties of a film layer, no ash and pruina, no water stain after drying as well as light flowing color and small color difference change in case of sealing the organic dyeing film; and the metal salt-free sealing agent is widely applicable to sealing treatment of an original-color anodic oxide film, an electrolytic coloring anodic oxide film, a hard oxide film and a dyeing anodic oxide film.

Fe base lithium sale compound anode materials and its making method

The invention discloses a ferrous lithium salt composite anode material and thepreparation method thereof. The technical problems which are needed to be solved are to enhance the high-rate electricity discharging of the anode material, and the manufacturing and the processing performances of battery electrodes are improved. The ferrous lithium salt composite anode material has lithium iron phosphate, and forms the composite material by adulterated with or covered by nickel-cobalt-manganese-lithium or nickel-cobalt-aluminum-lithium material. The weight ratio of the lithium iron phosphate and the nickel-cobalt-manganese-lithium or the nickel-cobalt-aluminum-lithium material is 9 to 7 : 1 to 3, and the micro-morphology is in a sphericity , or is like a sphericity, with a ration between a horizontal length and a vertical length of 1.2 to 2.5. The crystal is in the structure of an olivine type, a space group is Pbnm, and a particle diameter is 1 to 20microns. The preparation method comprises mixture, fusion processing and screen separation. Compared with the prior art, the ferrous lithium salt composite anode material has the advantages of capable of lowering specific surface area, capable of enhancing the voltage platform of the anode material, favorable processing performance, high tap density, favorable conductivity, favorable rate discharge performance and safe performance, capable of improving high and low temperature cycling performance, and favorable compatibility with various cathodes and electrolytes.
