[Lithium Battery: CATL's 350Wh/kg Aviation Battery Passes Adjacent Cell Thermal Runoff Validation]

Published: Aug 10, 2026 15:58
Recently, CATL's aviation power battery system developed for manned eVTOL aircraft successfully passed the adjacent cell thermal runoff non-propagation validation. This marks the world's first aviation power battery system utilizing 350Wh/kg high-energy-density prismatic cells to pass this test. This technological breakthrough and successful validation provide safer power assurance for the development of the low-altitude economy and represent another demonstration of CATL's continuous exploration of power battery safety boundaries. The entire process of cell and battery system production, inspection, and testing was conducted under the supervision of Civil Aviation Administration-designated representatives, laying a solid foundation for helping eVTOL aircraft meet civil aviation safety standards.

[Sinomine Resource Group: Subsidiary’s Two High-Purity Lithium Chemicals Production Lines Resume Production] On August 10, Sinomine Resource Group announced that its wholly-owned subsidiary Jiangxi Sinomine Lithium Industry, due to a mismatch between lithium concentrates transportation and production scheduling, temporarily shut down the "Annual 30,000 mt High-Purity Lithium Chemicals" and "Annual 35,000 mt High-Purity Lithium Chemicals" production lines for maintenance starting from June 30, 2026. With the maintenance now completed, the company has decided to resume production at the "Annual 30,000 mt High-Purity Lithium Chemicals" line on August 10, 2026, and plans to gradually resume production at the "Annual 35,000 mt High-Purity Lithium Chemicals" line in mid-August 2026.

[Black Mass Imports: Policy Channel Open, Yet Market Circulation Still Faces Multiple Bottlenecks] On June 1, 2025, a joint announcement by the Ministry of Ecology and Environment, the Ministry of Industry and Information Technology, and the General Administration of Customs officially took effect, removing compliant waste lithium-ion battery powder from the Catalogue of Solid Wastes Forbidden from Import and subjecting it to import management as ordinary goods. This marked a long-awaited policy breakthrough for China’s lithium battery recycling industry—prior to this, the channel for raw materials from outside China had never been legally accessible, and the industry relied almost entirely on domestically retired power batteries and off-cuts from battery factories.
