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.
In 2020, the lowest reported LFP cell prices were $80/kWh (12.5 Wh/$) with an average price of $137/kWh, [38] while in 2023 the average price had dropped to $100/kWh. [39] By early 2024, VDA -sized LFP cells were available for less than RMB 0.5/Wh ($70/kWh), while Chinese automaker Leapmotor stated it buys LFP cells at RMB 0.4/Wh ($56/kWh) and ...
