Why is a lithium-ion battery widely preferred by manufacturers of electronic gadgets?
Electronic gadget manufacturers prefer lithium-ion batteries, as they can take many forms. Li-ion batteries are lighter than other chemistries, which is why they are widely used in portable electronic devices. One major advantage of this battery is that it has no memory effect. You can recharge it anytime you like, whether the battery is nearly full or completely discharged. The self-discharge rate of lithium-ion batteries is approximately 5% per month, so they require less maintenance. These batteries can be recharged several times without replacements.
