The invention discloses a miniature lithium ion battery sealing assembly, and aims to provide a miniature lithium ion battery sealing explosion-proof cover which is compact in structure and good in explosion-proof effect. The assembly comprises an inner conductive metal body and an outer conductive metal body, the outer conductive metal body comprises a cover plate, an annular fixing piece and anouter cover, and the inner conductive metal body is a center cover. The outer conductive metal body has a double-layer structure, and the central cover is clamped by the insulator; the opening radiusof at least one layer of the annular fixing piece and the outer cover in the double-layer structure is asymmetric on the whole circumference, so that the width of the clamping part of the central cover of the inner conductive metal body is asymmetric. The invention is applied to the technical field of miniature lithium ion battery sealing assemblies. 本发明公开了一种微型锂离子电池密封组件，旨在提供一种结构紧凑,防爆效果好的微型锂离子电池密封防爆盖。本发明包括内外两个导电金属体，其中外导电金属体
