An SiO powder for secondary battery that is used as a negative electrode material of lithium secondary battery and characterized in that the concentration of contained hydrogen is = 80 ppm. The powder would enable striking enhancement of discharge capacity and rate of cycle capacity maintenance and thus would enable realization of a size reduction of lithium secondary battery and cost reduction thereof. There is provided a process for producing such an SiO powder, comprising mixing silicon dioxide powder with a silicon powder of = 30 ppm contained hydrogen concentration, heating the mixture at 1250 DEG to 1350 DEG C so as to achieve gasification of SiO, depositing the SiO on a deposition base, and thereafter carrying out pulverization thereof. Thus, the SiO powder can be produced with high efficiency and can realize substantial reduction of production costs, such as power cost, so that it can find a wide spectrum of application as an SiO powder for secondary battery.

Disclosed is a thermoplastic resin composition comprising a combination of 5 to 89.95 mass% of an aromatic polycarbonate resin (A), 5 to 60 mass% of an aliphatic polyester (B), 5 to 30 mass% of talc (C), 0.05 to 3 mass% of a silicone having a functional group (D), and 0 to 2 mass% of polytetrafluoroethylene (E), wherein the total amount of the components (A) to (E) is taken as 100 mass%, and wherein the ratio of the mass of the component (D) to the mass of the component (B) (i.e., a (D) / (B) ratio) is 0.003 to 0.6. The thermoplastic resin composition has remarkably improved flame retardancy and impact resistance, has excellent chemical resistance and heat resistance, and can be molded into an article having excellent appearance. Also disclosed is a molded article produced by using the thermoplastic resin composition.

The invention discloses an intelligent mark line printing machine and an automatic line printing technology adopting the intelligent mark line printing machine. The line printing machine comprises a machine table, a conveying belt, a line printing assembly, a drying device and a material collecting and stacking device. The conveying belt is matched with the machine table, and the line printing assembly is arranged on the machine tables and used for printing lines. Through a video camera, automatic visual positioning is performed, in combination with printing parameters set in a controller, positioning and generation of ink spraying trails are automatically performed on printed materials, then ink spraying line printing is finished in a full-automatic mode through the line printing assembly, the printed materials are automatically dried and collected, and therefore intelligent and automatic operation is achieved in the whole operation process.

An object of the present invention is to improve the initial charge-discharge efficiency and cycle characteristics of a non-aqueous electrolyte secondary battery using SiOX as a negative electrode active material. Provided is a negative electrode active material comprising particles made of SiOX containing a lithium silicate phase inside, and the surfaces of the particles made of SiOX are covered with carbon by 50% or more and 100% or less. In addition, the ratio of the number of moles of the lithium silicate phase to the total molar amount of the particles composed of the SiOX is 5 mol % or more and 25 mol % or less, and the average primary particle diameter of the particles composed of the SiOX is 1 μm or more and 15μm or less.
