[China's research and development of new lithium battery cathode materials can improve fast charging efficiency and durability] On October 2, the scientific research team of the Shenyang National Research Center for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, proposed a new strategy for cathode material design based on the laws of physical and chemical interactions of trace elements, promoting the exploration of cathode materials from "experience trial and error" to "goal-oriented". The relevant results were published in the international academic journal "Nature·Synthesis" on October 1. In response to the two problems of "lithium ions run slowly" and "the material structure is unstable", the scientific research team proposed a more targeted element screening method based on the underlying physical and chemical mechanisms: one type of elements is responsible for making lithium ions run more smoothly, and the other type of elements is responsible for making the material structure stronger. These two effects are closely related to the ionic charge density and metal-oxygen bonding strength of the element respectively. Elements with lower charge density can reduce the obstacles encountered during the migration of lithium ions, making it easier for lithium ions to move quickly in the material; elements that combine more firmly with oxygen can enhance the stability of the crystal skeleton, making the material less likely to undergo structural damage during repeated charge and discharge processes.

[The status of China's fishery resources and water ecological environment remains stable] On September 28, the Ministry of Agriculture and Rural Affairs and the Ministry of Ecology and Environment jointly issued the "Bulletin on the Status of China's Fishery Ecological Environment (2025)". The "Communique" shows that China's fishery resources and water ecological environment conditions will remain stable in 2025. In 2025, the Ministry of Agriculture and Rural Affairs organized 48 monitoring stations in the national fishery ecological environment monitoring network to conduct fishery resource surveys in the four major sea areas and important river basins such as the Yangtze River and Yellow River, and carried out routine monitoring of 18 indicators such as fishery water quality, sediments, and plankton in 164 important fishery waters. The "Bulletin" shows that the concentrations of zinc, lead, mercury and arsenic in all monitored waters are better than the evaluation standards; the proportion of chemical oxygen demand and petroleum-exceeding areas in important marine fishery waters dropped by 59.3% and 45.7% respectively, and the proportion of petroleum in important inland fishery waters dropped by 34.6%. The "Communique" includes for the first time the status of fishery resources in the four major sea areas and key river basins such as the Yangtze River and Yellow River, and analyzes the changing trends during the "14th Five-Year Plan". In 2025, 93 species, 202 species, 283 species, and 496 species of fishery organisms were surveyed in the Bohai Sea, Yellow Sea, East China Sea, and northern South China Sea respectively; There are 351 and 114 species of indigenous fish detected in the Yangtze River and Yellow River basins respectively. During the "14th Five-Year Plan" period, the fishery water environment is stable and improving. Chemical oxygen demand in important marine natural fishery waters, inorganic nitrogen in key seawater aquaculture areas, active phosphate in national aquatic germplasm resources reserves (ocean), and areas with chemical oxygen demand exceeding the standard dropped by 51.6% and 3% respectively. 3.7%, 55.4%, 90.2%; the proportion of total phosphorus in important fishery waters of rivers, total nitrogen in important fishery waters of lakes and reservoirs, and the area with permanganate index exceeding the standard in national aquatic germplasm resources protection areas (inland) decreased by 47.0%, 16.5%, and 22.8% respectively.
