The definition rule of 18650 battery model is: for example, 18650 battery refers to a cylindrical battery with a diameter of 18mm and a length of 65mm. Lithium is a metal element. Why do we call it a lithium battery? Because its positive pole is a battery with “lithium cobalt oxide” as the positive pole material. Of course, there are many batteries in the market now, including lithium iron phosphate, lithium manganate and other batteries with positive pole materials.

What is the purpose of 18650 lithium batter?
1. The life of 18650 lithium battery is theoretically more than 500 cycles of charging. It is commonly used in strong light flashlight, headlamp, mobile medical equipment, etc.
2. It can also be combined. There is also a difference between with and without a board. The main difference is that the protection of the board is over discharge, over discharge and over-current value, so as to prevent the battery from being scrapped due to outdated charging or too clean electricity.
3. 18650 is now mostly used in notebook batteries, and some strong light flashlight are also using it. Of course, 18650 has excellent performance, so as long as the capacity and voltage are appropriate, it is much better than batteries made of other materials, and it is also one of lithium batteries with high cost performance.
4. Flashlight, MP3, interphone, mobile phone. As long as the voltage is between 3.5-5v, the electric appliance can be distinguished from the No. 5 battery. 18650 means that the diameter is 18 mm and the length is 65 mm. The model of No. 5 battery is 14500, the diameter is 14 mm and the length is 50 mm.
5. Generally, 18650 batteries are widely used in industry, and are gradually introduced to civilian families. In the future, they will even be developed and distributed to rice cookers, induction cookers, etc. as backup power supply. They are often used in notebook batteries and high-end flashlight.
6. 18650 is only the size and model of battery. According to the type of battery, it can be divided into 18650 for lithium ion, 18650 for lithium iron phosphate and 18650 for nickel hydrogen (rare). At present, the common 18650 is more than lithium ion, which is widely used in various industries. 18650 lithium-ion battery is more perfect and stable in the world, and its market share is also the leading technology of other lithium-ion products.
