2025-06-17

The source reports that a China National Building Material Group institute launched China's first industrial continuous rotary kiln for chemical vapour deposition coating of silicon anode material. It states an annual capacity of 1500 tonnes and describes progress towards industrial production of next-generation lithium battery anodes.Pending confirmation

The source reports a theoretical silicon anode capacity of 4200mAh/g compared with graphite's theoretical maximum of 372mAh/g, describing an almost tenfold increase with implications for electric vehicle range and rapid charging.Pending confirmation

The source claims that the silicon anode CVD kiln technology reduced reliance on overseas suppliers and addressed industrialisation difficulties, supporting silicon anode development, the new energy vehicle supply chain and China's carbon goals.
