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;

The battery manufacturing process is mainly divided into two technical routes: lamination process and winding process. At present, the main technical direction of Chinese battery enterprises is mainly around winding, but with the progress of lamination technology, a large number of battery enterprises begin to enter the lamination field.

Instead of a set time in months, lithium polymer (Li-ion) batteries are rated for charge cycles. This means a full discharge and recharge cycle counts as one unit. Here's a breakdown of how long a Li-ion battery might last:

Over long-term use, the internal resistance of a lithium ion battery single cell inevitably increases. This increase in internal resistance is directly related to the battery's output efficiency, temperature rise, and safety performance.
