Title:
LAMINATED LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JPH04366554
Kind Code:
A
Abstract:
PURPOSE: To provide a simple lithium secondary battery with satisfactory energy efficiency.
CONSTITUTION: In a laminated type lithium secondary battery formed by alternately laminating a positive electrode 1 and a negative electrode 3 using lithium or an lithium alloy 4 in opposition to each other and charging an electrolyte between the positive electrode and the negative electrode, the fabric 2 of a carbon fiber having an electric specific resistance not more than 6μΩ.m, the a-axial directional crystal size of graphite crystal determined by X-ray diffraction method of 200-1000, the c-axial directional crystal size of 200-400, and a fiber diameter not more than 15μm is used as the positive electrode 1.
