On July 17, according to news from the State Administration for Market Regulation, the international standard for silicon-based anode materials, "Nanomanufacturing — Product specifications — Part 5-3: Nano energy storage — Blank detail specification: Nano-silicon-based anode materials for lithium-ion batteries", led by China, was officially released recently. This is also the first international standard in the field of silicon-based anode materials for lithium-ion batteries. It is reported that this international standard has for the first time established a system of key control characteristics for nano-silicon-based anode materials for lithium-ion batteries, clarified corresponding measurement methods, covering core characteristic indicators such as specific capacity, first-cycle Coulombic efficiency, and volume expansion rate, thus filling the gap in international standards for this field.
