Background technique

Soft pack batteries refer to polymer batteries packaged in aluminum-plastic film, usually lithium polymer batteries, which are mostly used in electronic devices such as mobile phones and tablet computers.

When installing and disassembling pouch batteries in electronic equipment, there are several methods as follows: method (1), the pouch battery is directly bonded to the battery compartment of the electronic device through ordinary tape with adhesive, in this method, due to The surface of the pouch battery is directly bonded to the ordinary tape, so when the pouch battery needs to be disassembled for maintenance, the pouch battery is pulled out of the battery compartment, and the surface of the pouch battery is easily deformed, damaged or wrinkled by the ordinary tape Wait. Damaged pouch batteries are prone to heat and swelling during use, which causes safety hazards in the process of using the pouch battery after repair, and even makes the pouch battery unable to be reused after repair. Method (2), in order to prevent the surface of the pouch battery from being directly bonded to the ordinary tape, the pouch battery is wrapped with a wrapping film. The wrapping method can be one or more layers of wrapping. The wrapping film can be the Transparent plastic film. After the pouch battery is wrapped with at least one layer of wrapping film, tape is used to bond the leaking head seam of the wrapping film, or the joint of the wrapping film has an adhesive, through which the wrapped Membrane head seams are bonded. Then, use ordinary adhesive tape to directly bond the soft pack battery wrapped with the wrapping film into the battery compartment of the electronic device, as shown in Figure 1, 101 in Figure 1 is the soft pack battery, 102 is the wrapping film, and 103 is the ordinary tape, 104 is a battery compartment. In this method (2), when disassembling the pouch battery, it is necessary to use a sharp tool such as a knife to peel off the wrapping film or tear it from the seam glued to the head of the wrapping film to take out the pouch battery.

Since the pouch battery is wrapped with a wrapping film, the adhesion between the wrapping film and the surface of the pouch battery is weak. When wrapping the pouch battery, the wrapping film easily forms a loose space, so that the pouch battery is easy to wrap Loose in the loose space of the membrane, resulting in poor wrapping effect and lower reliability. Moreover, in addition to wrapping the wrapping film with the film body, an adhesive is required to bond the seams, and the wrapping film is not easy to peel off, which makes it difficult to disassemble the pouch battery.

In the embodiment of the present application, a liquid is coated on the outer surface of the pouch battery and cured so that the liquid solidifies to form a wrapping film, and the wrapping film is attached to the outer surface of the pouch battery to integrally wrap the pouch battery. Then, when the pouch battery is assembled with the electronic device, the pouch battery is installed in the battery compartment of the electronic device through the sticky substance pasted on the wrapping film, and the pouch battery is taken out from the battery compartment by peeling off the wrapping film during disassembly . Since the liquid is solidified to form a wrapping film, the wrapping film is an integrated thin film layer, which can form a better integrated adhesion effect with the outer surface of the pouch battery, and has high reliability. Sticky substance pasted When installing the pouch battery in the battery compartment, because the wrapping film is thin, the wrapping film isolates the pouch battery from the sticky substance. When disassembling the pouch battery, it is easy to peel off the wrapping film and take it out of the battery compartment Soft pack battery.

For ease of understanding, the following describes the specific process of the pouch battery coating and disassembly process in the embodiment of the present application. Please refer to Figure 3. An embodiment of the pouch battery assembly and disassembly process in the embodiment of the present application may include:

301. Completely coat the liquid 31 on the outer surface of the pouch battery 32;
