AI Technical Summary
Technical Problem
Existing lithium-ion batteries have large space requirements, poor heat dissipation, high cost, and complex PCB design. Separating the nickel sheet from the MOS leads to wasted space and increased cost.
Method used
Design an L-type MOS package structure that integrates the MOS and nickel plate into one unit. The nickel plate can be used to dissipate heat from the MOS, reducing PCB space occupation. Furthermore, the MOS is packaged within a metal plate to improve mechanical strength and reduce costs.
Benefits of technology
Optimizes MOS heat dissipation, reduces PCB design complexity and space occupation, lowers costs, and improves battery reliability and capacity, making it suitable for the lithium-ion battery field.
