A large number of lithium-ion batteries are used inside cell phones, lap-top computers and many electronic devices. Lithium-ion battery is being improved continuously to increase energy density and prolong service life. In this paper, we have examined the effects of ambient temperature on service life of lithium-ion batteries. The maximum service duration is achieved at the temperature of 45℃. To extend the service time of portable devices, keep its lithium-ion battery at warmer condition by using the waste heat from electronic circuit.
