In order to strengthen the safety and quality management of lithium-ion batteries throughout their life cycle, the State Administration for Market Regulation (National Standards Committee) approved the release of the national standard "Lithium-ion Battery Coding Rules", which will be implemented on November 1, 2025.

This standard gives each newly produced battery product a unique identity code, and its scope of application covers all levels of products from single cells to battery systems. Through "one battery, one code", the entire life cycle process from production to recycling can be controlled, providing an important reference for product traceability and industry supervision.

Applicable product range

★ Single cell

★ Battery module

★ Battery pack

★ Battery cluster

★ Battery system
