A research team led by Professor Qiang Zhang from Tsinghua University has published a comprehensive analysis of energy storage technologies critical to China’s power system decarbonization. The study, featured in Technology Review for Carbon Neutrality, examines the multifunctional roles of storage systems across grid segments, evaluates core technologies from ultrashort-duration flywheels to seasonal hydrogen storage, and projects their deployment under cost and regional constraints. The work highlights policy mechanisms to support China’s transition to a carbon-neutral energy economy by 2060.

The flourishing development of the ‘low-altitude economy’ has not only enriched the aircraft industry but also expanded the application prospects of aircraft. However, this growth has also raised higher demands for the safety and intelligence levels of these aircraft. In emergency situations involving mechanical failures, adverse weather conditions, or strong interference, it is crucial for aircraft to autonomously select a suitable landing region and land safely. This can maximize the safety of both the aircraft and its occupants while minimizing economic losses. However, there is a lack of effective technical solutions for autonomous landing guidance under emergency conditions. This research focuses on this application and proposes a new monocular vision-based measurement method for autonomous aircraft landing guidance in unknown structured environments. The method enables the aircraft to autonomously select a suitable landing region and accurately measure the relative 6D pose (3D rotation and 3D translation) between the aircraft and the landing region, providing a reliable foundation for autonomous landing guidance.

Scientists from China have developed high-performance colloidal quantum-dot (CQD)  surface-emitting laser array based on circular Bragg resonator (CBR). The CQD CBR laser array, leveraging high-quality CQD material with low gain threshold and high stability and CBR cavity with strong optical confinement, features a low lasing threshold, high pixel density (2100 PPI), and a remarkable 1000-hour operation lifetime (3.63 × 10⁸ pulses) at room temperature, promising advancements for practical CQD laser applications in the future.

This study reports a high-temperature molten-salt system of KCl+LiOH+Li₂CO₃ to regenerate spent nickel-rich ternary cathodes. At elevated temperature, the molten-salt environment accelerates the conduction and transport of reaction ions, making the lithium replenishment process more efficient and sufficient. The upcycled cathode with single-crystalline structure effectively suppresses particle cracks and harmful side reactions during cycling, delivering a capacity retention of 81.2% after 200 cycles at 1 C, which is even significantly superior to commercial cathode.
