Today, when science and technology are highly developed, various high technologies appear in our lives and bring convenience to our lives. So, do you know that these high technologies may contain 18650 lithium-ion batteries?
As the most mature liquid lithium-ion battery type in the world, 18650 cylindrical lithium-ion batteries are widely used in mobile terminal devices, especially tablets and smartphones, whether in single cells or battery packs. However, the structural characteristics of the 18650 battery inevitably lead to some defects. Since the explosion accident was announced, it was caused by a short circuit in the 18650 lithium-ion battery (pack): if it is used improperly or has a design problem, the internal pressure of the lithium-ion battery (pack) will be too high. In the event of a leakage pressure, the pressure of the battery's hard case (steel or aluminum case) can cause the case to explode. The capacity of large-capacity 18650 lithium-ion batteries is usually between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If it is combined into a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack can easily exceed 5000mah. 18650 lithium-ion battery has high safety performance, is non-explosive and non-flammable; is non-toxic, non-polluting, and has passed RoHS trademark certification; can achieve various safety performances in one go, with more than 500 cycles; high temperature resistance, discharge at 65 degrees Efficiency reaches 100%. To prevent the battery from short-circuiting, separate the positive and negative terminals of the 18650 lithium-ion battery. Therefore, the short circuit phenomenon may be reduced to the limit. A protective plate can be installed to prevent the battery from overcharging and over-discharging, which can also extend the battery life.
Current power bank products use lithium-ion batteries as energy storage units. There are two technical routes for this lithium-ion battery. One is the battery cell of a liquid lithium-ion battery. The so-called 18650 lithium-ion battery is a model with a diameter of 18mm and a height of 65mm. The other is a lithium polymer battery, usually designed as a prismatic lithium-ion battery. Lithium polymer batteries can also power many devices because they can be in any shape. High safety performance 18650 lithium-ion battery has high safety performance. To prevent battery short circuit, separate the positive and negative electrodes of the 18650 lithium-ion battery. Therefore, the short circuit phenomenon may be reduced to the limit. A protective plate can be installed to prevent the battery from overcharging and over-discharging, which can also extend the battery life. The capacity of 18650 lithium-ion battery is generally between 1200mah~3600mah, and the general battery capacity is only about 800. If 18650 lithium-ion batteries are combined into a 18650 lithium-ion battery pack, the 18650 lithium-ion battery pack can easily exceed 5000mah. The biggest disadvantages of the 18650 lithium-ion battery are its fixed size and poor placement when installed in some laptops or certain products. Of course, this shortcoming can also be said to be an advantage. This is compared to other lithium-ion batteries, such as polymer lithium-ion batteries. In terms of customizable and transformable sizes, this is a drawback. It becomes an advantage compared to some products with specified battery specifications. In fact, when it comes to lithium-ion batteries, the reasons for the explosion are understandable. After all, the stability of this kind of battery was not strong in the past, but as a lithium-ion battery with very high performance comparison, its application is bound to become more and more widespread. After all, when it comes to this essential battery, the 18650 lithium-ion battery is the best choice.
