Abstract

The invention discloses a safe combined cylindrical lithium battery cap assembly, which comprises a cylindrical lithium battery body, wherein the cylindrical lithium battery body comprises a protective shell, a cap is arranged at the top part of the protective shell, an arc-shaped frame is welded to the bottom part of the cap, a telescopic frame is integrally formed at the bottom part of the arc-shaped frame, an insulating ring is arranged between the outer portion of the telescopic frame and the protective shell, a battery cell is arranged in the cylindrical lithium battery body, a contact plate is welded to the top part of the battery cell, a fixing plate is welded to one side of the inner wall of the protective shell, limiting plates are welded to the two sides of the telescopic frame, fixing grooves are formed in the bottom parts of the limiting plates, insulating pads are arranged in the fixing grooves, and compression springs are arranged at the bottom parts of the insulating pads. According to the safe combined cylindrical lithium battery cap assembly, the phenomenon of electric quantity leakage when the cylindrical lithium battery is not used is avoided, the use convenience of the cylindrical lithium battery is improved, the use stability of the cylindrical lithium battery is improved, flame leakage when the cylindrical lithium battery is on fire is avoided, and the use safety of the cylindrical lithium battery is improved.

Description

technical field [0001] The invention relates to the technical field of cylindrical lithium batteries, in particular to a safe combination cylindrical lithium battery cap assembly. Background technique [0002] Cylindrical lithium batteries are divided into lithium cobalt oxide, lithium manganese oxide, and ternary materials. The three material system batteries have different advantages. Batteries are widely used in: notebook computers, digital cameras, lighting fixtures, toys, power tools, portable mobile energy and other fields. Lithium batteries can be roughly divided into two categories: lithium metal batteries and Lithium Ion Battery. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries. Due to their own high technical requirements, only a...
