Will 18500 lithium battery expand after use?

Introduction Will 18500 lithium battery expand after use? There are two reasons for the expansion of lithium batteries, commonly referred to as "bulges." The first is the level of battery manufacturing.

Will 18500 lithium battery expand after use?

18500 lithium batteries will expand after use.

Lithium battery expansion is commonly referred to as “bulge.”

There are two reasons. The first is the problem of battery manufacturing level, uneven electrode coating and production. the manufacturing is relatively crude. To put it simply, the quality of the lithium battery itself is not good enough; the second problem is overcharging and overdischarging during use. These two factors will cause a violent short circuit-like reaction inside the battery during use, generating a large amount of heat, which in turn will cause the electrolyte to decompose and vaporize, causing a swelling of the battery.

Based on the situation you described, it should be an overload problem.

If the battery is bulged, please stop using it'to use. Continuing to use an inflated battery will significantly increase the risk of explosion.

What type of battery is it?

Companies with mature battery cell technology include BAK, Tiansheng, Huayuebao and others manufacturers, with stable performance. The rules for defining its model are: For example, the 18650 type refers to a battery with a diameter of 18 mm and a length of 65 mm. The 18500 battery has a diameter of 18 mm and a length of 50 mm, and is a cylindrical battery.

What is the difference between 18650 battery and general lithium battery?

1. This is a cylindrical lithium battery. Since there is no exact mark on the battery, it is a cylindrical lithium battery. It cannot be confirmed whether it is 14500. 18500 or 18650 battery, according to experience, it belongs to 18650 battery.

2. This is a disassembled battery, that is, the battery has been assembled before. Due to various factors, the assembled battery was disassembled after the battery cells were disassembled, good products with normal appearance. and performances are selected for secondary use; It can also be seen on the battery that there are residual solder joints on both ends of the battery, and there are obvious traces of spot welding on the positive and negative terminals.

3. This is an unlicensed battery. The battery has no brand logo, no battery capacity logo, no battery model logo, etc. It is produced through abnormal channels, has no quality assurance and no safety guarantee. . The battery is a low-end battery type.

Generally speaking, this battery has many dangerous factors. Dianchizhidu does not recommend that you use it at the same time, since the amount youtake is not important, I sincerely hope you can throw it away. It’s time to eliminate hidden dangers.

The advantages of 18650 lithium battery compared with ordinary batteries are:

1. Large capacity

: The capacity of 18650 lithium battery is generally between 1200mah and 3600mah. The general battery capacity is only about 800. If 18650 lithium batteries are combined to form a 18650 lithium battery, the 18650 lithium battery can easily exceed 5000 mah.

2. Long service life:

The 18650 lithium battery has a long service life. The lifespan can reach more than 500 times under normal use, more than twice that of an ordinary battery. batteries.

3. High safety performance:

18650Lithium batteries have high safety performance, do not explode or burn; are non-toxic, non-pollutingtes and have passed RoHS brand certification; they are integrated in one go, with a number of cycles greater than 500; good high temperature resistance and the discharge efficiency reaches 100% at 65 degrees.

To prevent battery short circuit, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the possibility of short circuit has been reduced to the extreme. A protection board can be installed to prevent the battery from overcharging and overdischarging, which can also extend battery life.

4. High voltage:

The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the voltage of 1.2V nickel-cadmium and nickel-metal hydride batteries.
