On June 29th, a group of 11 top science and technology experts from the Chinese Academy of Engineering, research institutes, and universities visited Guanghan, Sichuan to evaluate the scientific achievements of the “non-hydrogen fluoride process for the preparation of hexafluorophosphate at the molecular level.†The expert panel confirmed that the world's first industrialization project verification line for the “non-hydrofluoric acid process to prepare lithium hexafluorophosphate†has officially gone into operation, marking a major breakthrough for China in the field of lithium-ion battery materials. This development signals that China is no longer dependent on foreign technologies for key components in lithium batteries.
Whoever controls lithium battery technology holds the future of the new energy industry
"At this stage, it can be said that whoever controls lithium battery technology will shape the future of the new energy industry," said Gan Yong, an academician and vice president of the Chinese Academy of Engineering. He emphasized that the “non-hydrofluoric acid process for the preparation of lithium hexafluorophosphate†is a milestone in the evolution of lithium battery technology and the broader new energy sector. The 100-ton industrial verification line, launched in Guanghan, Sichuan, has demonstrated that the molecular-level production of lithium hexafluorophosphate has reached international standards.
The future of electric vehicle core technology in China
The appraisal panel highlighted that the successful operation of the world’s first industrial verification line for the non-hydrofluoric acid process marks China’s breakthrough in overcoming technical barriers in lithium hexafluorophosphate production. This achievement is expected to challenge the long-standing dominance of Japan and South Korea in this critical area. Moreover, it is anticipated to significantly enhance the global competitiveness of China’s lithium-ion battery industry.
Li Yao, chairman of Shenzhen Waterma Battery Co., Ltd., stated that the application of advanced technologies such as lithium hexafluorophosphate and lithium iron phosphate has led to significant improvements in performance while cutting costs by 50%. "In the future, whether it's batteries or battery materials, the core technology of electric vehicles will be in China," he added. (Xu Mengxi)
