[0002] A lithium-ion battery cell consists of five parts: the electrode, separator, tab, electrolyte, and packaging film. The electrode typically refers to a high-potential electrode containing active substances that undergo a reduction reaction during discharge. A lithium-ion battery electrode is a coating composed of particles evenly applied to a metal current collector. Simply put, it's the core of the cell—one positive and one negative—that generates electricity. The tabs connect the electrodes, which then connect to other electrodes to ensure power flow.
