What is a cylindrical lithium battery?

Safely harness pure lithium energy with Panasonic Cylindrical Lithium. A lightweight, high-energy-density battery optimized for stable discharge in high-drain applications such as flash-enabled cameras, Cylindrical Lithium is perfect for continuous or intermittent use over long periods in various devices exposed to wide range of temperatures.

What are the naming rules for lithium ion batteries?

The naming rules for cylindrical lithium-ion battery cells follows a standardized format based on the cell’s dimensions, and usually represented by a five-digit code, where each digit provides specific information about the cell’s dimensions. Here’s a breakdown of the representation: What does 18650 means?

How many Li-ion cylindrical battery cells are there?

This paper investigates 19 Li-ion cylindrical battery cells from four cell manufacturers in four formats (18650, 20700, 21700, and 4680). We aim to systematically capture the design features, such as tab design and quality parameters, such as manufacturing tolerances and generically describe cylindrical cells.

What does the 5th digit mean in a lithium ion battery?

Fifth Digit: The fifth digit indicates the cylindrical shape of the cell. Typically, it’s “0” for cylindrical cells. By following this naming convention, we can easily identify the size and shape of cylindrical lithium-ion battery cells. Putting it all together, let’s take an example: What does 21700 means?

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

How long can a cylindrical lithium battery last?

Panasonic Cylindrical Lithium can be safely stored without significant loss of capacity for periods up to 10 years* with improved resistance to heat and cold compared to other battery types. Cylindrical Lithium battery technology by Panasonic Energy Co., Ltd. High Energy Formula and PTC Safety System.
