Patent ID: 7763376

Claim:
A solid electrolyte battery, comprising: (a) an elongated positive electrode comprising an elongated positive-electrode collector having two sides on which positive-electrode active material layers are formed; (b) an elongated negative electrode comprising an elongated negative-electrode collector having two sides on which negative-electrode active materials layers are formed; and (c) a solid electrolyte layer formed on at least either surface of the positive electrode and the negative electrode, wherein a solid electrolyte consists of a gel electrolyte, including a polymer material with a weight of about 5% to about 50% of the weight of the gel electrolyte, wherein, the elongated positive electrode and the elongated negative electrode are laminated such that the surfaces on which each of the electrolyte layers are formed are disposed opposite to each other, the total thickness of the positive-electrode active material layers is between approximately 60 μm to 150 μm, and a ratio A/B of the total film thickness A of the positive-electrode active material layers with respect to the total thickness B of the negative-electrode active material layers satisfies a range 0.5 to 1.2, and the elongated electrodes are encapsulated by a laminated film, and a lead of the positive electrode and a lead of the negative electrode connected to the elongated electrodes are drawn out to the outside portion of the laminated film.
