Lithium-ion has a higher energy density at 150/200 Wh/kg versus lithium iron phosphate at 90/120 Wh/kg. There are significant differences in energy when comparing lithium-ion and lithium iron phosphate. The charge rate of lithium iron phosphate is 1C and the discharge rate of 1-25C. It has a specific energy of 90/120 watt-hours per kilogram and a nominal voltage of 3.20V or 3.30V. Lithium iron phosphate has a cathode of iron phosphate and an anode of graphite. Its charge rate is from 0.7C up to 1.0C as higher charges can significantly damage the battery. It has a specific energy of 150/200 watt-hours per kilogram and a nominal voltage of 3.6V. Lithium-ion can consist of two different chemistries for the cathode, lithium manganese oxide or lithium cobalt dioxide, as both have a graphite anode. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. Chemistries of Lithium Iron Phosphate and Lithium-IonĬharge and discharge rates of a battery are governed by C-rates. Lithium iron phosphate is a newer type of battery gaining recognition in the manufacturing industries due to its cost-effective materials and stability with high temperatures. Most people are familiar with lithium-ion as they most likely own a smartphone, tablet, or PC. While they both share some similarities, there are major differences in high-energy density, long life cycles, and safety.
#Cheap lithium ion batteries portable
Lithium-ion and Lithium iron phosphate are two types of batteries used in today’s portable electronics.
Newer technologies, from smartphones to electric vehicles to portable power tools, require batteries that can hold a significant amount of energy, be lightweight enough to carry or move, and be safe for the user. Lithium batteries offer all these benefits for portable electronics, vehicles, medical equipment, and even grid energy storage. When using power sources to run embedded components, it’s not always simple to pop in a fresh set of batteries. Anton Beck is the Battery Product Manager at Epec.
