About lithium ion battery 18650 price.First, I will introduce the 18650 lithium ion battery.The 18650 lithium battery is one of the lithium-ion batteries, many people choose it . as its have excellent practical capacity and adaptability in a variety of scenarios. Today we introduce the 18650 lithium battery from the perspective of user purchase, including the definition, quotation and type difference of 18650 lithium battery.
The 18650 lithium battery is the first lithium-ion battery. SONY company in JAPAN set a standard lithium-ion battery model for cost savings in the past: 18mm in diameter and 65mm in length, 0 is a cylindrical battery. The common 18650 battery is divided into a lithium ion battery and a lithium iron phosphate battery. The lithium-ion battery voltage is 3.6V and 4.2V, the lithium iron phosphate battery voltage is 3.2V, the capacity is usually 1200mAh-3000mAh, and the common capacity is 2200mAh-3600mAh.
Lithium Ion Battery (Li-ion, Lithium Ion Battery): Lithium-ion batteries are widely used because of their light weight, large capacity, and no memory effect. Many digital devices use lithium-ion batteries as power supplies, despite their price. Relatively expensive. Lithium-ion batteries have a high energy density, and their capacity is 1.5 to 2 times that of nickel-hydrogen batteries of the same weight, and has a very low self-discharge rate. In addition, the lithium-ion battery has almost no “memory effect” and does not contain toxic substances, which is also an important reason for its wide application.
Lithium batteries are the same as 3.7V or 4.2V. It’s just that the manufacturer’s label is different. 3.7V refers to the platform voltage (ie, typical voltage) that is discharged during battery use, while 4.2 volts refers to the voltage at full charge. Common rechargeable 18650 lithium batteries, the voltage is 3.6 or 3.7v, when fully charged is 4.2v. During the charging process of the battery, the voltage of the battery gradually rises to 4.2V at 3.7V. The charging of the lithium battery cannot charge the no-load voltage to 4.2V or higher, otherwise the battery will be damaged. This is a special place for the lithium battery.
