Cylindrical Lithium-ion Cell Applications
Lithium-ion batteries have the advantages of light weight, large capacity, and no memory effect, so they are widely used. Many digital devices use lithium-ion batteries as power sources, although they are relatively expensive. The energy density of lithium-ion batteries is very high, its capacity is 1.5 to 2 times that of nickel-metal hydride batteries of the same weight, and it has a very low self-discharge rate.
