Lithium-ion battery

Also called: Li-ion battery A lithium-ion battery stores and releases electrical energy through reversible electrochemical reactions involving lithium ions. During charging and discharging, lithium ions move through the electrolyte while electrons travel through the external electrical circuit. Lithium-ion describes a family of battery chemistries rather than one cell recipe. EV batteries can use different cathode, anode and electrolyte materials, which changes energy density, cost, charging behaviour and thermal characteristics. Lithium-ion batteries dominate current battery-electric vehicle production because they can combine high energy storage with rechargeable cycle life and high power output.
