[0002] Existing battery structures generally include positive and negative plates, electrolyte, battery cell, separator, positive and negative terminals, upper casing (i.e., cover), and lower casing that is fixedly connected to the upper casing. The battery cell and other related components are located inside the lower casing.

[0003] In existing technologies, battery assembly typically involves first pairing and arranging the cells and then installing them in a cell frame. The assembled cell assembly is then placed in the lower casing of the battery, and workers weld the positive and negative terminals of the cell assembly to the positive and negative terminals on the upper casing. Currently, the entire process cannot be automated because most circuit connections are fixed using flexible wires or nickel sheets, resulting in high production costs. Furthermore, manual welding requires skilled workers and leads to low overall production efficiency. During battery recycling, inspection, and maintenance, disassembly also requires slow, manual disassembly of the casing, tidying up the wiring, and removing the cell assembly, a time-consuming and labor-intensive process. Therefore, improvements are needed to address these issues. Utility Model Content
