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.

Apple Inc. clarifies that a charge cycle means using all the battery's capacity, but not necessarily by discharging it from 100% to 0%: "You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your ...
Lithium-ion battery Curve of price and capacity of lithium-ion batteries over time; the price of these batteries declined by 97% in three decades. Lithium is the alkali metal with lowest density and with the greatest electrochemical potential and energy-to-weight ratio.
Aqueous Li-ion batteries have a relatively short battery cycle life, ranging from 50 to 100 cycles. As of 2018, research is being conducted to increase the number of cycles to 500 to 1000 cycles, allowing them to feasibly compete against other types of batteries that have a higher energy density.

The best NMC batteries exhibit specific energy values of over 300 Wh/kg. Notably, the specific energy of Panasonic’s “2170” NCA batteries used in Tesla’s 2020 Model 3 mid-size sedan is around 260 Wh/kg, which is 70% of its "pure chemicals" value. LFP batteries also exhibit a lower operating voltage than other lithium-ion battery types.
