Secondary electrochemical battery sealing body with encapsulated type chip shield structure and battery

Abstract

The invention provides a secondary electrochemical battery sealing body with an encapsulated type chip shield structure. The sealing body comprises a cathode cap, a circuit board module and an insulating washer, wherein a sunk wire turn structure is formed at one end, near the cathode cap, of a battery shell; the circuit board module is positioned between the wire turn and the cathode cap; the length of the diameter of the circuit board module is set between the sunk inner diameter formed by the wire turn and the inner diameter of the battery shell, so that the circuit board module is clamped on one side of the wire turn; the circuit board module and the cathode cap are connected through a conducting material, and form a first enclosed electromagnetic shielding space; the battery shell and the circuit board module form a second enclosed electromagnetic shielding space; electronic components are arranged in the first enclosed electromagnetic shielding space and the second enclosed electromagnetic shielding space; the section of the insulating washer adopts a shape referring to the description; the insulating washer is arranged in the interspace among the battery shell, the circuit board module and the cathode cap, presses and fixes the circuit board module between the wire turn and the battery shell, and insulates the battery shell and the cathode cap.

Description

technical field [0001] The invention relates to a secondary battery, in particular to a secondary electrochemical battery sealing body and battery with a packaged chip heat dissipation structure. Background technique [0002] In recent years, secondary batteries (also called rechargeable batteries) have been widely used in various portable electrical and electronic devices, such as toys, handheld devices, etc., which put forward higher and higher requirements for energy storage of secondary batteries. Due to the advantages of high energy, high power discharge, and environmental protection, lithium-ion secondary batteries are gradually being used in the above fields. [0003] The normal work of the rechargeable battery often needs to cooperate with other functional integrated circuit chips to achieve the ideal working effect. Usually the rechargeable battery and the integrated circuit chip are packaged separately, and then used together through the connection of the circuit ...

AI Technical Summary

Problems solved by technology

The space utilization rate of the polymer cell has a great relationship with the energy density and capacity of the lithium-ion secondary battery. Generally, the greater the space utilization rate of the polymer cell, the greater the energy density and capacity of the lithium-ion secondary battery. The capacity is also larger, therefore, the existing lithium-ion secondary batteries generally have the problem of low energy density and capacity of lithium-ion secondary batteries due to the low space utilization of polymer cells.
