[Sinopec and LG Chem sign contract to jointly develop key battery materials] Sinopec and LG Chem recently signed an agreement to jointly develop key materials for sodium ion batteries. Both parties will jointly develop key materials such as positive and negative electrode materials for sodium ion batteries in the energy storage system and low-speed electric vehicle markets in China and globally, accelerate the commercialization process, expand the business model of sodium ion batteries, and expand cooperation in the fields of new energy and high value-added materials in the future. Sodium ion batteries have a similar working principle to lithium-ion batteries, mainly achieving charge transfer through the insertion and extraction of sodium ions between the positive and negative electrodes. Compared to lithium batteries, sodium ion batteries have resource and price advantages, as well as better safety and charging speed. At low temperatures, sodium ion batteries experience less capacity degradation, perform better than lithium iron phosphate batteries, and have broad market prospects.Editor/Bian Wenjun

• [Two projects of Weifang to Zoucheng Expressway have been approved for preliminary land use]
• Recently, the Weifang to Zoucheng Expressway Weifang to Yiyuan section and Changle connecting line project, invested and constructed by Shandong Expressway Group, received preliminary land use approval from the Ministry of Natural Resources. It only took 23 working days from obtaining preliminary design approval to obtaining preliminary land use approval, laying a solid foundation for smooth construction. Since obtaining the preliminary design approval, the project preparation team has organized multiple special meetings with relevant units such as survey and demarcation, inventory and evaluation to discuss organizational plans, arrange dedicated personnel to monitor the progress in real time, strengthen communication and cooperation with government departments at all levels along the line, concentrate on tackling obstacles and difficulties, strengthen policy research, and efficiently promote milestone work such as inventory and evaluation. In this project, the Weifang to Yiyuan section has a total length of 84.61 kilometers, starting from the Baifenzi hub where the Weiri Expressway intersects with the Weiqing Expressway and ending at the Linlin Expressway east of Yuezhuang Town, Yiyuan County, Zibo; The Changle connecting line has a total length of 23.03 kilometers, starting from the Jiwei Expressway in the northwest of Honghe Town, Changle County, Weifang, and ending at the Weizhou Expressway in the east of Dasheng Town, Anqiu City. The implementation of the project is of great significance for improving the layout of the regional expressway network, promoting interconnectivity between the Jiaodong and Lunan economic circles, driving regional economic and social development, and developing tourism resources along the route.

• [China Power Construction won the bid for flood control project with 427 million yuan]
• Recently, the EPC general contracting project for ecological flood control and restoration in Anlan Honggou and Xigu Honggou has been announced as the winning bidder. The consortium formed by East China Survey and Design Institute Co., Ltd. of China Electric Power Construction Group and China Water Resources and Hydropower Sixth Engineering Bureau Co., Ltd. has successfully won the bid with a bid price of 427 million yuan. This project includes four major sections: main channel management, branch channel management, special improvement, and information technology engineering. The main ditch treatment will build a 3.4-kilometer flood channel slope protection and bottom protection, and a 0.8-kilometer embankment; The management of the tributary involves the construction of 6.57 kilometers of ecological revetment; The special upgrading project will build 18.135 kilometers of patrol roads; The information technology project will build a digital twin base plate and a flash flood warning system. Six companies participated in this bidding process, and after evaluation, four companies entered the final stage. The joint venture of China Electric Power Construction East China Institute is far ahead with a comprehensive score of 92.38 points. The joint venture of Gansu Provincial Water Resources and Hydropower Engineering Bureau and Yangtze River Survey, Planning, Design and Research Co., Ltd. in second place scored 70.04 points, while the joint venture of China Electric Power Construction Kunming Institute in third place quoted 421 million yuan. Industry analysis believes that the technological accumulation of Zhongdian Jianhua East Institute in the field of water conservancy informatization is the key factor for its victory. The winning bid of this project marks an important step forward in the construction of ecological governance and flood control system in Gansu Province by 2025, which will provide strong support for local water security.
