Abstract
The utility model relates to an explosion-proof structure for a column-type lithium battery, which comprises a top cap, a housing, gaskets, rubber mats, and thin film, wherein the housing is connected with the top cap; and the gaskets, the rubber mats, and the thin film are arranged in the cavity of the housing. The explosion-proof structure further comprises sealing rings arranged on the contact surface of the housing and the thin film. The sealing rings and the thin film form linear sealing after encapsulation and compression, so that the sealing performance of an explosion proof cover is greatly improved, and battery fluid leakage is prevented; and the housing made of stainless iron has strong physical properties and is less susceptible to breakage.
Description
Technical field
The utility model relates to the technical field of lithium battery, particularly relates to a kind of column type lithium cell and uses blast resistance construction.
Background technology
Along with the development of lithium-ion electric pool technology, its cost performance improves constantly, and causes it by all trades and professions extensive use.Especially, the lithium battery stable performance has extended cycle life, and is the battery with high-energy-density, is to be widely used on the digital series products at present.
The big capacity of column type lithium cell, long service life has been widely used in each field at present.But the structure of the Explosion-proof cap of present column type lithium cell is the top cap, with the shell that the top cap is connected, establishes pad in shell and the top cap, rubber cushion, film; Because for face contacts, have sealing problem between them between shell and the film, electrolyte is prone to and leaks.Influence the normal use of battery.
The utility model content
The purpose of the utility model is to provide a kind of column type lithium cell to use blast resistance construction, and it can overcome above-mentioned defective, prevents that leaking from appearring in electrolyte.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of column type lithium cell is used blast resistance construction; It comprises crown cap, shell, pad, rubber cushion and film; Described shell links to each other with the top cap; Described pad, rubber cushion and film are located in the cavity of described shell, wherein: it also further includes sealing ring, and described sealing ring is located on the contact-making surface of described shell and film.
Preferably, above-mentioned shell is made with stainless iron.
Preferably, above-mentioned shell is provided with explosionproof hole.
After adopting technique scheme, after encapsulation compressed, sealing money and film formed linear sealing, had improved the sealing property of Explosion-proof cap greatly, prevented battery generation leakage, and the shell that stainless iron is processed has stronger physical property, and housing is cracky not.
