Lithium-ion refers to a family of rechargeable battery chemistries where lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. It encompasses various specific cathode materials like LFP, NMC, and NCA, all characterized by high energy density and lack of memory effect.
