A RECHARGEABLE LITHIUM-ION POWER BATTERY AND MANUFACTURE METHOD OF THE SAME

WIPO Patent Application WO/2003/077348

A1

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 positiv- 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 plate-shaped structure which is composed of a positive electrode sheet, a negative electrode sheet and separator. Either the positive electrode sheet or the negative electrode sheet is shaped to a long expanded sheet with a big-leaf single tab or big-leaf multiple tabs which have different space , 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.
