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.
