Lithium batteries are classified into lithium ion batteries and lithium polymer batteries. The electrolyte of a lithium-ion battery is fluid, and therefore, it is more unstable than a lithium polymer battery.
The lithium battery standard 3.7V or 4.2V is actually the same, but the manufacturer has labeled it differently. 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.
Lithium battery encyclopedia lithium battery pack does not discharge phenomenon: Lithium battery pack is charged into the device after charging, the device can not work, the open circuit voltage of the battery pack does not change or change little.
Lithium battery case design can be divided into: PVC heat seal, plastic, metal
