Title:
AN RECHARGEABLE LITHIUM-ION POWER BATTERY AND MANUFACTURE METHOD OF THE SAME
Document Type and Number:
WIPO Patent Application WO/2003/077349
Kind Code:
A1
Abstract:
A rechargeable lithium-ion power battery, each mono-cell is consisted of a cover plate, a negative pole , a safety valve, a positive pole, an electrolyte solution and a case. The positive pole is connected with the positive electrode, and the negative pole is connected with the negative electrode. Positive electrode substrate is selected from an aluminum foil with certain thickness, which is coated with positive active material on both sides. Negative electrode substrate is selected from copper foil with certain thickness, which is coated with negative active material on both sides. It is characterized in that an inner body of the battery is an electrode assembly which has multi-layer laminated structure which is composed of one or more pairs of electrodes, that is positive electrode, negative electrode, and separator, in this electrode assembly, the positive electrode sheet and the negative electrode sheet are separately positioned in sequence. Either the positive electrode sheet or the negative electrode sheet is shaped into rectangle sheet with big-leaf single tab or big-leaf multiple tabs, current flows to the poles by means of current-collecting clamp. The positive electrode has one or more electrode poles; the negative electrode has one or more electrode poles. Amount of the positive pole can be same with that of the negative pole, or different; diameter of the pole can be same, or different.
