AI Technical Summary
The end face of the electrode assembly in existing lithium-ion battery cells is a planar structure, which cannot be adapted to irregularly shaped cell covers, resulting in low space utilization. The overall design leads to high cost and poor platformization, and damaged parts need to be replaced as a whole.
It adopts a modular electrode design, including the electrode body and the split body. It can be flexibly disassembled and assembled through the plug slot and plug boss. It uses an insulated and isolated current-conducting connector for electrical connection, reducing space occupation and supporting the adaptation of irregularly shaped battery cell cover plates.
It improves the space utilization and capacity of battery cells, reduces replacement costs, supports the adaptation of multiple battery cell models, and enhances assembly efficiency and electrical safety.
