ICR18650-26H pdf datasheet



ICR18650-26H is lithium-ion rechargeable cell. A lithium-ion rechargeable cell, often referred to simply as a lithium-ion battery, is a type of rechargeable battery that has become widely popular for various portable electronic devices and applications due to its high energy density, relatively lightweight design, and rechargeable nature. Lithium-ion batteries have replaced many other types of batteries in consumer electronics, electric vehicles, and renewable energy systems.

1. ICR: This is a code that indicates the chemical composition of the battery. “ICR” stands for “Lithium Cobalt Rechargeable,” which means the battery uses a lithium-cobalt oxide (LiCoO2) cathode chemistry.

2. 18650: This is a standard format for cylindrical lithium-ion battery cells. The “18650” designation indicates the physical size and shape of the cell. In this case, it means the cell has a diameter of approximately 18 millimeters and is around 65 millimeters in length.
