【Chinese Team Develops Long-Lasting "Health" Monitoring Technology for Lithium-Ion Batteries】Recently, Professor Tingrui Pan and Researcher Yu Chang from the Suzhou Institute for Advanced Research, University of Science and Technology of China, collaborated with Professor Peng Tan's team from the University of Science and Technology of China, and jointly worked with Professor Yongbing Tang and Researcher Fan Zhang's team from the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, to successfully develop an efficient and stable in-situ expansion force monitoring technology for lithium-ion batteries. The research findings have been published in the journal National Science Review.
This new technology utilizes the electrolyte and materials inherent to lithium-ion batteries to construct a sensing interface, enabling high-precision pressure monitoring without the need for additional encapsulation steps. This design is highly compatible with battery materials, effectively addressing the stability issues of traditional flexible pressure sensors in corrosive environments. Experiments have demonstrated that this technology can sensitively respond to expansion force changes at the pascal level and operate stably inside the battery for over a month.

In January, national passenger car producers' new energy wholesale estimates reached 900,000 units, up 1% YoY.

According to the latest data from the Passenger Car Association, in December 2025, producers with new energy wholesale sales exceeding 10,000 units accounted for 93% of the total wholesale sales of passenger NEVs that month. Based on preliminary January data, these producers achieved sales of 830,000 units in January. As most producers have already locked in their major sales figures, by applying the structural proportion from the previous month to the current month's data, the estimated wholesale sales of passenger NEVs nationwide in January were 900,000 units. According to comprehensive preliminary monthly association data: the estimated wholesale sales of NEVs by national passenger car producers in January 2026 were 900,000 units, up 1% YoY.
