Lithium-ion battery
OverviewHistoryDesignFormatsUsesPerformanceLifespanSafety
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life. Also note…

Among the secondary batteries, LIB (lithium-ion battery) is popular due to its high specific energy (Es) and low self-discharge rate, but the power capability and cycle life of LIB are limited. For example, some LIBs can supply a minimum Es of 200 Wh/kg, but a maximum specific power of <350 W/kg [37] .
