Technical FAQs 4

What is a Panasonic cylinder lithium battery?

The system includes a thermosensitive PTC that detects temperature rises and increases resistance to prevent short-circuit; a built-in safety valve to relieve internal pressure; and durable gasket material that’s effective at preventing leaks. Panasonic Cylindrical Lithium is UL recognized battery. Reliable in a Wide Range of Temperatures

What is a cylindrical lithium ion battery?

Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.

Do lithium ion batteries have internal protective devices?

Limitations of Internal Protective Devices in High-Voltage/High-Capacity Batteries Using Lithium-Ion Cylindrical Commercial Cells Most commercial cylindrical 18650 Lithium-Ion (Li-Ion) cells have two internal protective devices: the Positive Temperature Coefficient (PTC) and the Current Interrupt Device (CID).

What is a positive thermal coefficient (PTC) current limiting switch?

Most commercial, cylindrical lithium-ion cell design are equipped with a positive thermal coefficient (PTC) current limiting switch to provide hazard protection against short circuits external to the cell. This device, shown in Figure 1, is thin annulus consisting of a specially irradiated polyethylene laminated with a metal on both sides .
