± Electrodes: Positive electrode (lithium iron phosphate, ternary lithium, etc. coated on aluminum foil); negative electrode (graphite, etc. coated on copper foil)

Electrodes: The core part of the battery, composed of active substances, additives, and a conductive framework (current collector).

≈ Electrolyte: Main component is lithium hexafluorophosphate

Electrolyte: One of the main components of the battery, it transmits charges between the positive and negative electrodes.

Ⅰ Separator: An insulator that separates the positive and negative electrode plates while allowing ions to pass through.

Separator: One of the main internal components of the battery, it separates the positive and negative electrodes to prevent short circuits due to contact, while still allowing ions to pass through.

□ Shell: Cylindrical batteries use steel or aluminum shells; square batteries generally use aluminum shells; pouch batteries typically use aluminum-plastic film.
