3.7v battery cell Manufacturers

1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

As is known to all, BYD started from lithium iron phosphate battery and has stuck to this field for a long time. However, a statement recently issued by BYD was a surprise.

Lithium iron phosphate battery is a lithium ion battery with lithium iron phosphate (LiFePO4) as the cathode material and carbon as the cathode material. The rated voltage of the single battery is 3.2V, and the charging cut-off voltage is 3.6V~3.65V.

With the popularity of electric vehicles, more and more people begin to pay attention to the battery. The battery is the energy storage warehouse of electric vehicles. Electric vehicles convert electric energy into chemical energy when charging and store it in the battery. When using electric vehicles, the motor converts the chemical energy in the battery into mechanical energy, so that electric vehicles can run on the road. Since the battery is the power source of electric vehicles, What kinds of batteries are currently used in electric vehicles and which battery is better?

What is the difference between 18650 lithium battery cell and lithium polymer battery?
