<p>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 a long and foldable negative sheet, some positive electrode sheets and separator, and in this electrode assembly, the positive electrode sheets and the negative electrode sheet are separately positioned in sequence. Either the positive electrode sheets or the negative electrode sheet i, -; 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.</p> |
