The 21700 cylindrical lithium-ion battery cell is a key specification in the lithium-ion battery field. With its balanced performance in capacity, energy density, and power output, it has become a core power supply component for high-energy-consumption equipment and large-scale energy storage scenarios. Its technological iteration and application expansion are driving the upgrading of related industries.

The following will elaborate on it in terms of basic composition, working principle, core performance, application scenarios, and usage precautions.

Lithium cobalt oxide polymer battery is a type of lithium-ion battery using lithium cobalt oxide as the cathode material and polymer as the electrolyte. With the core advantages of high energy density and flexible form factor, it has become the mainstream choice in the consumer electronics field, while also featuring distinct characteristics in terms of cost and safety. The following is a detailed explanation from dimensions such as core attributes, performance, application scenarios, and technical improvements.

The classification of lithium polymer batteries is centered on the material system, mainly divided based on three core dimensions: cathode materials, anode materials, and electrolyte materials. Different material combinations determine key performance metrics such as energy density, safety, and cycle life, making them suitable for diverse application scenarios.
