Embodiment Construction
[0035] The lithium-ion battery structure of the preferred embodiment of the present invention is as figure 1 shown, see also figure 2 , which includes a sealed casing 20, the casing 20 is provided with a cell, and the outer surface of the casing 20 is provided with a positive tab 31 and a negative tab 32 connected to the cell. An air duct 10 is also provided inside the housing 20 , and a sealed hole 25 is provided on the housing 20 . One end of the airway tube 10 is opened in the shell 20, and the other end of the airway tube 10 is open to the hole 25 on the shell 20. The diameter of the hole 25 is suitable for the diameter of the airway tube 10, and the pressure of the sealing part of the hole 25 is lower than that of the shell. 20 other sealing parts. In this way, when the gas inside the battery casing 20 generates a relatively high pressure, the sealing part of the opening of the air duct 10 can be opened earlier than other parts on the casing 20, so that the gas is disc...

Abstract
The invention relates to a lithium-ion battery and a manufacturing method thereof, wherein the lithium-ion battery includes a sealed casing, an electric cell is arranged inside the casing, positive and negative electrodes connected to the electric cell are arranged on the outer surface of the casing, and a battery cell is arranged inside the casing. The air duct is provided with a sealed hole on the outer shell; one end of the air duct is opened in the outer shell, and the other end of the air duct is connected to the hole, and the sealing part of the hole can bear less pressure than other sealing parts on the outer shell. When the gas inside the battery casing generates a large pressure, the sealing part of the opening of the air duct can be opened before other parts of the casing, so that the gas can be discharged through the air duct, which improves the safety of the lithium-ion battery. In addition, the airway can replace the airbag in the traditional solution to complete the vacuuming process in the lithium-ion battery manufacturing process, which saves the aluminum-plastic film wasted by the airbag and reduces the production cost of the lithium-ion battery.
Description
technical field [0001] The invention relates to the technical field of batteries, and more specifically, to a lithium-ion battery and a manufacturing method thereof. Background technique [0002] With the wide application of lithium-ion batteries in mobile phones, notebook computers and other digital products, people's requirements for the performance of lithium-ion batteries are getting higher and higher. Not only do they hope that lithium-ion batteries have excellent electrochemical performance and low price , At the same time, lithium-ion batteries are required to have reliable safety performance. [0003] The shells of existing lithium-ion batteries are divided into metal shells and plastic shells. Metal shells include steel shells and aluminum shells, etc., and non-metallic shells include plastic shells and aluminum-plastic film packaging. Among non-metallic packaging materials for lithium-ion batteries, soft-packaged lithium-ion batteries using aluminum-plastic films ...
