    FAQs about Why can lithium batteries generate electricity

    What is a lithium-ion battery and how does it work?

    The lithium-ion (Li-ion) battery is the predominant commercial form of rechargeable battery, widely used in portable electronics and electrified transportation.

    Why are lithium ion batteries better than other batteries?

    Lithium-ion batteries have higher voltage than other types of batteries, meaning they can store more energy and discharge more power for high-energy uses like driving a car at high speeds or providing emergency backup power.

    They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would. If you completely discharge a lithium-ion battery, it is ruined. A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
