China has officially unveiled the world's first international standard for silicon-based anode materials used in lithium-ion batteries, titled "Nanomanufacturing - Product specifications - Part 5-3: Nano-energy storage - Blank detail specification: Nano-silicon-based anode materials for lithium-ion batteries." This milestone signifies China's leadership in establishing a benchmark for the industry. The standard not only introduces a pivotal control characteristic system for these materials but also delineates precise measurement methods for critical indicators such as specific capacity, initial Coulombic efficiency, and volume expansion rate. Furthermore, it addresses a long-standing void in international standards pertaining to this specialized field.
