Lithium Battery Definition
Lithium ion battery (Li-ion, Lithium Ion Battery): Lithium-ion battery has the advantages of light weight, large capacity, no memory effect, etc., and thus has been widely used - many digital devices use lithium-ion batteries for power, despite its price Relatively expensive. Lithium-ion batteries have a high energy density. Their capacity is 1.5 to 2 times that of NiMH batteries of the same weight, and they have a very low self-discharge rate. In addition, the lithium ion battery has almost no "memory effect" and does not contain toxic substances and other advantages are also important reasons for its wide application. In addition, please pay attention to the outside of the lithium battery generally marked with English 4.2V lithiumion battery (lithium battery) or 4.2V lithium secondary battery (lithium secondary battery), 4.2V lithiumion rechargeable battery (rechargeable lithium battery), so the user must buy the battery must Observe the sign of the appearance of the battery block to prevent the cadmium nickel and hydrogen nickel batteries from being mistaken for the lithium battery because the battery type was not clearly seen.
