Battery Manufacturing Terminology
Typically, it refers to the electrode sheet containing active materials that undergo reduction reactions during discharge, and it has a relatively higher electrical potential.
A battery component made of an ion-permeable material that prevents contact between electrode tabs of opposite polarity within the battery from causing a short circuit.
A combination formed by encapsulating one or multiple core packs, connecting the electrode tabs, and then leading out the terminal post.
A metallic conductor that connects the internal electrode sheets of a battery with terminals.Note: In the case of multi-tab batteries connecting with terminals, additional connecting strips may be introduced to reinforce the tabs.
Substances that undergo electrochemical reactions during the charge and discharge processes of a battery to store or release electrical energy. They are divided into positive electrode active materials and negative electrode active materials.
"A substance, either liquid or solid, that contains mobile ions and possesses ionic conductivity.Note: Electrolytes can be in liquid, solid, or gel form and do not conduct electrons."
Encapsulating internal components of the battery and providing protective elements to prevent direct contact with the external environment.
A multi-layer composite film material, known as an aluminum-plastic film, consisting of plastic, aluminum foil, and adhesive. It is used for encapsulating pouch-type lithium-ion batteries and provides high strength, excellent barrier properties, and resistance to electrolytes.
Components used for sealing the battery casing, typically equipped with injection ports, safety valves, and terminal lead-out holes, among other features.
The conductive component that facilitates the external circuit's connection to the negative electrode of the battery, also known as the "negative electrode terminal."
The conductive component that facilitates the external circuit's connection to the positive electrode of the battery, also known as the "positive electrode terminal."
A structural component designed to release the gas generated inside the battery in order to prevent excessive internal pressure. It is designed with a pressure release threshold based on the characteristics of the battery.
Conductors used to carry current between various components in the battery circuit.
The electronic management system that connects the battery and equipment, with main functions including real-time monitoring of battery physical parameters, battery state estimation, online diagnosis and warning, charge, discharge, and pre-charge control, balance management, and thermal management.
A lithium-ion battery with the shape of a parallelepiped, featuring six faces meeting at right angles.
A cylindrical lithium-ion battery with a total height equal to or greater than its diameter.
