In general, polymer lithium batteries are more expensive than cylindrical lithium-ion batteries. This is mainly because polymer lithium batteries are more complex in design, requiring the use of special polymer electrolytes and materials such as thin aluminum foil, as well as higher-level manufacturing technology.
Polymer lithium batteries have high energy density, thinner design, lower internal resistance and better safety performance, so they are widely used in certain applications, such as smartphones, tablets and portable electronic devices. However, due to high manufacturing costs, the market price of polymer lithium batteries is relatively high.
In contrast, cylindrical lithium-ion batteries have a simpler design and manufacturing process and use a more common liquid electrolyte, so the manufacturing cost is relatively low. Cylindrical lithium-ion batteries are mainly used in power tools, electric vehicles, energy storage systems and other fields.
It should be noted that the specific price difference will be affected by factors such as market supply and demand, brand influence, capacity and quality. Therefore, when buying batteries, in addition to paying attention to price, but also consider factors such as battery performance, safety and suitability to choose the most suitable battery type for your needs.
