Abstract
This utility model relates to the field of aluminum-cased energy storage battery technology, specifically a multi-layer electrode structure for a square aluminum-cased energy storage battery. The multi-layer electrode structure includes multiple positive and multiple negative electrodes, with the negative electrodes disposed between the positive electrodes. A separator is provided between the positive and negative electrodes. A positive current collector is electrically connected to the upper ends of the positive electrodes, and a negative current collector is electrically connected to the upper ends of the negative electrodes. Rectangular frames are fixedly provided on both the upper and lower sides of the multi-layer electrode structure. The rectangular frames have slots for limiting the position of the positive and negative electrodes. A locking mechanism for quick locking and unlocking is provided between the two rectangular frames. The locking mechanism includes connecting plates, with two connecting plates fixedly disposed on the upper sides of the lower rectangular frame. This utility model reduces the probability of deformation of the positive and negative electrodes, thereby improving the internal stability and safety of the square aluminum-cased energy storage battery.
