摘要:
A predetermined pattern of thick film, made of a material sintering-resistant at 1000° C. or lower, is screen printed on both surfaces of a green sheet to form constraint layers. The constraint layer has non-print regions in areas where via contacts are to be formed, where the constraint layer is removed in circles having a diameter of about 250 μm. Subsequently, via holes are formed in the green sheet and the contact holes are filled with a conductor paste by screen printing to form via contacts. Then a stack of such green sheets is pressed and integrated with a hydrostatic press device to obtain a green body. Next the green body is fired at lower temperature to obtain a low-temperature co-firable ceramic multilayer substrate.

A substrate has a base, an intermediate layer, a conductive layer, and conductive films. The base is a ceramic insulator. The intermediate layer is on a main surface of the base. The conductive layer is on the intermediate layer. The conductive films are on the conductive layer, covering an exposed portion of the conductive layer.

摘要:
A process of preparation capable of easily preparing cathode materials having a homogeneous composition in a good mass productivity, a cathode material obtained by this process, and a secondary lithium ion battery using the cathode material. Aqueous solutions of each of a lithium salt, a transition metal salt, and a complexing agent are prepared and mixed in a stoichiometric ratio of a cathode material, and therefrom water is removed by spray-drying to give a precursor which is then sintered. High performance secondary lithium ion batteries are obtained by using the obtained cathode material in the positive electrode.
