Types of 26650 Lithium Batteries

There are two main types of 26650 lithium batteries: lithium cobalt oxide (LiCoO2) and lithium iron phosphate (LiFePO4). Lithium cobalt oxide (LiCoO2) 26650 battery has high energy density, high discharge voltage, high power output capability, and high cycle life. Lithium iron phosphate (LiFePO4) 26650 battery has high safety, good thermal stability, long cycle life, low self-discharge rate, and low cost (compared to lithium cobalt oxide battery). Lithium cobalt oxide batteries are suitable for applications that require high energy density and higher power output, while lithium iron phosphate batteries are suitable for applications that require higher safety and cycle life.
