Description

A power battery with waterproof function

technical field

The invention relates to the technical field of power battery products, in particular to a structure and manufacturing technology of an 18650 battery.

Background technique

The 18650 battery has the characteristics of large capacity, and its capacity is generally between 1200-3100mah, while the general battery capacity is only about 800mah. If combined into a 18650 battery pack, it can easily exceed 5000mah; the service life of the 18650 battery is very long. The cycle life can reach more than 500 times, which is more than twice that of ordinary batteries; the 18650 lithium battery has high safety performance, no explosion, no combustion, no toxicity, and no pollution; it has good high temperature resistance, and the discharge efficiency reaches 100% at 65°C; The voltage of 18650 batteries is generally above 3.6 or 3.7, which is much higher than the 1.2V voltage of NiCd and NiMH batteries; 18650 batteries have no memory effect, and it is not necessary to empty the remaining power before charging, which is more convenient to use. Therefore, 18650 batteries are widely used in electronic equipment such as notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, model airplanes, toys, video cameras, and digital cameras.

However, the 18650 lithium batteries currently on the market are not designed to be waterproof, which leads to the fact that the battery does not have a waterproof function. If the battery is used in a humid environment, it is easy to cause water to enter the battery. After entering the water, it is easy to cause dangerous events such as short circuit, fire, and explosion. Therefore, The current 18650 lithium battery has potential safety hazards and is not suitable for use in humid environments, let alone in water.

Contents of the invention

The technical problem to be solved by the present invention is to provide a safe, reliable, wide adaptable and waterproof power battery.

In order to solve the above technical problems, the present invention adopts the following technical solutions: a power battery with waterproof function, including a battery core, an outer casing and an output wire, the battery core is installed in the outer casing, and the output wire is connected to the battery core and passed through the outer casing. It is characterized in that: there is waterproof glue in the gap between the output line and the outer packaging; the corner connection of the outer packaging is sealed with sealing adhesive paper; in a waterproof bag.

Further, the waterproof operation process is as follows: the first step is to apply waterproof glue to the gap between the output line and the outer shell package for sealing; the second step is to paste the sealing tape on the corner connection of the outer shell package ; The third step is to put the whole battery sealed with sealing tape into a waterproof bag. The mouth of the waterproof bag is located on the side where the output line goes out, and apply waterproof glue to the gap between the mouth of the bag and the outer packaging. Seal the mouth of the bag.

Further, the waterproof bag is a PE waterproof bag.

Further, the waterproof glue is waterproof silica gel.

In the present invention, waterproof silica gel is applied to the gap between the output line and the outer casing, and a sealant paper is pasted on the corners of the outer casing to seal the edge, and then the battery is put into a waterproof bag as a whole, and the mouth of the waterproof bag is sealed. It is sealed with waterproof silicone, so it has double-layer sealing and waterproof protection, so that the present invention eliminates the potential safety hazard caused by water ingress, is not only safer and more reliable, but also can be used in wet environments, and can even be used in water.
