Problems solved by technology

[0003] However, the existing lithium batteries have the potential of overheating and catching fire. In recent years, there have been more and more reports about lithium batteries igniting and burning, especially when lithium batteries are fast-charging, the possibility of catching fire is greater
According to the analysis, during fast charging, the lithium fiber is attached to the carbon electrode inside the lithium battery, and this phenomenon will cause the battery to short circuit, which will cause the battery to overheat and burn, or even explode, causing serious damage to the equipment and personnel. serious damage

Embodiment 1

[0037] Such as figure 1 As shown, the present invention provides a high-safety lithium-ion battery module, including: a packing box, an air valve, a positive sealing passage, a negative sealing passage, a positive terminal connector, a negative terminal connector and a battery; wherein, the battery can be lithium Ion single cells, lithium-ion battery packs or lead-acid batteries, etc.

[0038] The packing box is a hollow airtight container, the inside of which is used to accommodate the battery; the gas valve is arranged on the packing box, and is used to fill the inside of the packing box with an inert gas or non-combustible or non-combustible gases that support combustion;

[0039] The bottom end of the positive electrode sealing channel is open and located inside the packing box, the top end of the positive electrode sealing channel is sealed and located outside the packing box, and the positive terminal connector is installed on the top end of the positive electrode seali...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that in Embodiment 1, the environment where the battery is located is an oxygen-free gas environment, while in this embodiment, the environment where the battery is located is an oxygen-free liquid environment, and its structure is: including: Packing box, positive electrode sealing channel, negative electrode sealing channel, positive terminal connector, negative terminal connector and battery; wherein, a liquid injection hole for injecting a flame retardant liquid into the inside of the packing box can be provided on the packing box, and of course, it can also be placed on the During the production process, the inside of the packaging box has been injected with flame retardant liquid, so there is no need to provide a liquid injection hole on the packaging box.

[0044] The packing box is a hollow airtight container, the inside of which is used to accommodate the battery; the space of the packing box where the b...

Embodiment 3

[0048] This embodiment provides a method for manufacturing a high-safety lithium-ion battery module, including the following steps:

[0049]S1, placing the battery inside the sealed packaging box, making the positive output terminal of the battery electrically connected to the positive terminal connector through the positive sealing channel; making the negative output terminal pass through the negative sealing a channel electrically connected to the negative terminal connector;

[0050] S2, making the internal environment of the packaging box where the battery is located be an oxygen-free environment; wherein, the oxygen-free environment may be a gas anaerobic environment or a liquid anaerobic environment.

[0051] (1) Gas anaerobic environment

[0052] The method for realizing the oxygen-free gas environment is as follows: evacuate the inside of the packaging box through the air valve to make it reach a vacuum state, and then fill the inside of the packaging box with inert g...

Abstract

A high-safety-performance lithium ion battery module and a manufacturing method thereof are provided. The lithium ion battery module comprises a packaging box, a gas valve, a positive electrode sealing channel, a negative electrode sealing channel, a positive electrode terminal connector, a negative electrode terminal connector and a battery. The interior of the packaging box is used for accommodating the battery. The gas valve is used for inflating inert gas or non-combustion gas or gas which does not support combustion to the interior of the packaging box. The bottom end of the positive electrode sealing channel is provided with an opening, and is disposed inside the packaging box. The top end of the positive electrode sealing channel is sealed and located outside the packaging box. The positive electrode terminal connector is installed at the top end of the positive electrode sealing channel. The bottom end of the negative electrode sealing channel is provided with an opening and is located inside the packaging box. The top of the negative electrode sealing channel is sealed and located outside the packaging box. The negative electrode terminal connector is installed at the top of the negative electrode sealing channel. When a conventional battery is installed inside the battery outer package, the battery combustion phenomenon caused by overheating can be effectively prevented, and therefore the safety of used devices and the safety of users are guaranteed.

Description

technical field [0001] The invention relates to a battery, in particular to a high-safety lithium-ion battery module and a manufacturing method thereof. Background technique [0002] Because lithium batteries have many advantages such as large capacity, light weight, high voltage, small size and no memory characteristics, they have been widely used in mobile phones, notebook computers, digital cameras, video recorders and other equipment. [0003] However, existing lithium batteries have the potential of overheating and catching fire. In recent years, there have been more and more reports about lithium batteries igniting and burning, especially when lithium batteries are fast-charging, the possibility of catching fire is greater. According to analysis, during fast charging, the lithium fiber is attached to the carbon electrode inside the lithium battery, and this phenomenon will cause the battery to short circuit, which will cause the battery to overheat and burn, or even ex...
