ABSTRACT:
A type of winding assembly type lithium ion secondary power battery includes: winding assembly type electrode cores wound with positive electrodes, negative electrodes and a separation membrane, electrolyte, and a battery shell. Its characteristics are: the interior of the battery shell carries at least one electrode units formed by electrode holders holding many stacked electrode cores. The terminal leads of the current collector for all positive and negative electrode cores are led from the upper and lower ends of the electrode unit respectively. The positive and negative terminals on cover boards and the outer side of the cover boards are connected to terminal leads of the current collector by built-in fasteners. There is a separation ring between the electrode core body of the battery and the cover boards of the battery. The present invention simplifies the manufacturing technology, increases the energy density of the battery, the mechanical property and safety property of the battery, and has an excellent high discharge property.
