Li-ion battery

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.

Cathode typically refers to the electrode where reduction reactions occur.Note: The cathode is the positive electrode during discharge and the negative electrode during charging.

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.

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 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.
