Information

Lithium cobalt oxide, one of the most common Lithium ion batteries, has the chemical symbols LiCoO2 and the abbreviation LCO. Its high specific energy makes Li-cobalt the popular choice for mobile phones, laptops and digital cameras. The battery consists of a cobalt oxide cathode and a graphite carbon anode. The cathode has a layered structure.

 

Li-cobalt should not be charged and discharged at a current higher than its C-rating. This means that an 18650 cell with 2,400mAh can only be charged and discharged at 2,400mA. Forcing a fast charge or applying a load higher than 2,400mA causes overheating and undue stress. For optimal fast charge, the manufacturer recommends a C-rate of 0.8C or about 2,000mA. The mandatory battery protection circuit limits the charge and discharge rate to a safe level of about 1C for the Energy Cell.

Li-cobalt excels on high specific energy but offers only moderate performance specific power, safety and life span.

 

Summary Table

Voltages 3.60V nominal; typical operating range 3.0–4.2V/cell
Specific energy (capacity) 150–200Wh/kg. Specialty cells provide up to 240Wh/kg.
Charge (C-rate) 0.7–1C, charges to 4.20V (most cells); 3h charge typical. Charge current above 1C shortens battery life.
Discharge (C-rate) 1C; 2.50V cut off. Discharge current above 1C shortens battery life.
Cycle life 500–1000, related to depth of discharge, load, temperature
Applications Mobile phones, tablets, laptops, cameras
Comments Very high specific energy, limited specific power. Cobalt is expensive. Serves as Energy Cell.
