Solid-state battery material suppliers struggle to achieve and verify ultra-high purity levels (99.99%+) for commercial production

Battery material manufacturers in China's EV supply chain face critical challenges in producing solid-state battery materials with the extreme purity specifications (99.99%+) required by major OEMs like CATL. Current production and quality verification processes are bottlenecks preventing scale-up, as even minor impurities can degrade battery performance, safety, and lifespan. Suppliers lack reliable, cost-effective methods to consistently achieve and certify these purity levels at commercial volumes.
