Its high specific energy makes lithium cobalate a popular choice for mobile phones, laptops and digital cameras. The disadvantages of lithium cobalate are its relatively short life, low thermal stability and limited load capacity (specific power). Like other cobalt mixed lithium ion batteries, lithium cobalate uses graphite cathode. Its cycle life is mainly limited by the solid electrolyte interface (SEI), which is mainly manifested in the gradual thickening of the SEI film, and the problem of lithium plating on the anode during rapid or low temperature charging. Newer material systems add nickel, manganese, and/or aluminum to improve life, load capacity, and reduce costs.

　　Lithium cobalate performance in terms of quantity. Lithium cobalate performs well in terms of high specific energy, but can only provide general performance in terms of power characteristics, safety and cycle life.
