Abstract: A method for manufacturing a bending-tolerant multilayered flexible circuit board (FPC) suitable for use in a disposable biosensor chip includes manufacturing and bending a single-sided FPC. The single-sided FPC includes a base layer, a wiring layer, and through holes. The wiring layer includes first and second wiring areas. A first bending area is formed between each first wiring area and the corresponding second wiring area, the through holes forming an easy bending line. The second wiring area is bent relative to the first wiring area along the bending line to obtain the multilayered FPC.

Abstract: A lithium ion battery diaphragm includes a film and a ceramic layer, the ceramic layer is formed on at least one surface of the film to form a structure in the shape of a grid on the at least one surface of the film. A method for manufacturing the lithium ion battery diaphragm is also provided.

Abstract: The present invention relates to a negative electrode for lithium ion rechargeable battery and a manufacturing method thereof. The negative electrode comprises at least one vermicular graphite and at least one pitch, wherein the vermicular graphite is fabricated by way of thermally treating an expandable graphite powder, and the pitch is adsorbed in the pores of the vermicular graphite. In the present invention, the pitch adsorbed in the vermicular graphite would be carbonized and graphitized, such that a composite graphite having multi-layer flake graphite is formed, and the composite graphite is further pulverized to a composite graphite powder. Moreover, the manufacturing method of the present invention can be used for fabricating the negative electrode for lithium ion rechargeable battery under the conditions of reducing manufacturing cost and solvent usage, so as to protect the environment from the manufacturing process pollution.
