Abstract
The utility model relates to a gas collection device in a lithium battery, which comprises a connector, a gas pipe, a check valve and a gas collector, wherein the connector is used for connecting the gas outlet of the lithium battery; the two ends of the gas pipe are respectively connected with the connector and the gas collector; the gas pipe is connected with the check valve in series; and gas flows into the gas collector through the check valve. In the utility model, through the connection of the connector and the gas outlet of the lithium battery and the serial connection of the check valve and the gas pipe, when a large amount of gas is generated in the lithium battery, and the air pressure in the lithium battery is larger than that of the outside, gas flows out of the lithium battery and enters the gas collector through the gas pipe and the check valve is used to prevent gas backstreaming, thus gas can be stored in the gas collector. The device is simple to install, is convenient to operate, and can prevent gas backstreaming.
Description
Technical field
The utility model relates to a kind of gas collector, especially a kind of high capacity lithium ion battery internal gas gathering-device.
Background technology
But because lithium ion battery have voltage height, specific energy big, have extended cycle life, characteristics such as security performance is good, the little fast charging and discharging of self discharge, therefore in the various aspects of extensive use people productive life, become people's indispensable essential product in the life of working gradually.Lithium ion battery discharge and recharge, in the storage process, because chemical reaction has a certain amount of gas to produce, and electric core residual moisture in dry run is residual also can to cause the electrolyte hydrolysis, also can produce gas, when the gas in the battery reaches a certain amount of, if can not in time discharge, will cause but battery bulging even blast.Therefore, collect the gas in the battery, gas is carried out qualitative and quantitative analysis, analyze the reason that produces gas, thereby the performance of battery is improved, improve battery performance and become the task of top priority.
Summary of the invention
The purpose of this utility model provides a kind of lithium battery interior gas collector, collects the problem of difficulty to solve lithium battery interior gas.
For achieving the above object, a kind of lithium battery interior gas collector of the present utility model comprises connector, tracheae, unidirectional valve and gas collector, described connector is used to connect lithium cell safety valve, described tracheae two ends connect described connector and gatherer respectively, string is provided with unidirectional valve in the tracheae, and gas flows in the gatherer by this unidirectional valve.
Further, the end that links to each other with the lithium battery gas outlet on the described connector is provided with gas-tight thread.
Further, the gas-tight thread of described connector is an internal and external threads.
Further, also be connected with snap joint on the described connector and between the tracheae.
A kind of lithium battery interior gas collector of the present utility model links to each other with lithium cell safety valve (or being called the gas outlet) by connector, and string is established unidirectional valve in tracheae, in lithium battery, produce a large amount of gas, the air pressure of lithium battery interior is during greater than the air pressure of outside, gas flows out in lithium battery, enters gas collector by tracheae, and unidirectional valve stops gas backstreaming, thereby make atmosphere storage in gas collector, this device is installed simple, easy to operate and can be prevented that gas from flowing backwards.
Connector is provided with gas-tight thread with the end that the lithium battery gas outlet links to each other, so that connector is threaded with lithium cell safety valve, has guaranteed the air-tightness of system.
The use of snap joint realizes the quick replacing of connector.
