What are the significant advantages of lithium-ion batteries?

Lithium-ion batteries (LIBs) offer significant advantages over traditional battery technologies.Lithium - ion batteries ( LIBs ) excel with high energy density ( up to 150 Wh / kg ) for compact power storage 12,500- ,000 charge cycles ensuring longevity 2, low self - discharge (<10% monthly ) surpassing NiMH batteries , and eco - friendliness by avoiding toxic metals . Recent breakthroughs further enable ultra - fast charging (80% in 12 minutes ) , addressing a key EV adoption barrier .
