China releases proposed standards for battery recycling

The Ministry of Industry and Information Technology (MIIT) in China has introduced revised guidelines for battery recycling companies that aim to be state-approved or “whitelisted.” The draft document, titled “Industry Standard Conditions for Comprehensive Utilization of Waste Power Batteries of New Energy Vehicles (2024 Edition),” is currently open for industry consultation. The previous standards were introduced in 2019 providing broad guidelines for the industry. The new guidelines set out extensive criteria for companies in the battery recycling sector, covering aspects such as facility specifications, business structures, and technology standards. This initiative reflects the Government’s commitment to enhancing the efficiency, safety, and environmental sustainability of the battery recycling industry.

Recovery rates

The new proposal outlines stricter recovery rate requirements, with the lithium recovery rate now set at 90%, an increase from the 85% proposed in 2019. Recovery rates for nickel, cobalt, and manganese remain unchanged at 98%. Additionally, the draft introduces new recovery targets of 98% for copper, aluminium, and rare earth metals, which were not specified under previous guidelines.

Environmental standards

Significant updates have been made to the environmental standards that facilities must meet. For instance, the energy consumption for producing one tonne of lithium carbonate is capped at less than 2,220 tonnes of coal equivalent, approximately 18 MWh. The document also mandates that fluorine emission recovery must exceed 99.5%, a new inclusion given that fluorine, which can form the highly corrosive gas hydrogen fluoride, was not previously addressed. Moreover, wastewater recycling at these facilities is required to achieve a 99% efficiency rate, and all plants must be located on industrial land.

Utilisation rates and battery reuse

The draft standards also …
