CATL Enlists Google, Xiaomi, and BMW to Draft Global Battery Standards

Battery supply chain leader CATL has expanded into a global standardisation alliance, joining brands such as Google, Xiaomi, BMW, Renault, and Volvo to launch a unified circular economy framework. The platform establishes a structured development pathway for future battery asset management and vehicle lifecycle regulation, CATL confirmed. The engineering initiative centres on developing a Battery Circular Design Guide, scheduled for full release in 2027. The framework introduces uniform criteria for cell diagnostics, pack disassembly simplification, and battery remanufacturing. Technical parameters will set structural evaluation metrics for both electric passenger cars and heavy commercial logistics vehicles. By establishing uniform lifecycle rules, automotive manufacturers and fleet operators can accurately calculate asset value and manage financial placement risks. The Ellen MacArthur Foundation is coordinating the cross-industry collaboration to align corporate strategies with carbon reduction targets. Value chain emissions from mining and raw material processing remain five times higher than emissions from core factory operations. To address this, the manufacturer is utilising recycled components, reducing material carbon intensity by 32 percent. Its subsidiary Brunp processed 210,000 tonnes of battery waste in 2025, recovering 99.6 percent of core minerals. To expand overseas infrastructure, the company is partnering with Octopus Energy to build a commercial vehicle network in Europe, following the initial introduction of heavy-duty truck battery swap systems. The new project leverages engineering verified on a 1,250 km battery swap corridor implemented on domestic logistics routes last year. Operational monitoring shows that 1,000 efficiency projects have reduced core factory emission intensity by 77 percent since 2022. These manufacturing clean-up efforts enabled the company to achieve operational carbon neutrality across all its battery manufacturing facilities last year. Standardised emission reductions ensure that future international battery cell exports maintain full structural alignment with upcoming Western environmental mandates.
