Development of sustainable and efficient recycling technology for spent Li-ion batteries: Traditional and transformation go hand in hand

Clean and efficient recycling of spent lithium-ion batteries(LIBs)has become an urgent need to promote sustainable and rapid development of human society.Therefore,we provide a critical and comprehensive overview of the various technologies for recycling spent LIBs,starting with lithium-ion power batteries.Recent research on raw material collection,metallurgical recovery,separation and purification is highlighted,particularly in terms of all aspects of economic efficiency,energy consumption,technology transformation and policy management.Mechanisms and pathways for transformative full-component recovery of spent LIBs are explored,revealing a clean and efficient closed-loop recovery mechanism.Optimization methods are proposed for future recycling technologies,with a focus on how future research directions can be industrialized.Ultimately,based on life-cycle assessment,the challenges of future recycling are revealed from the LIBs supply chain and stability of the supply chain of the new energy battery industry to provide an outlook on clean and efficient short process recycling technologies.This work is designed to support the sustainable development of the new energy power industry,to help meet the needs of global decarbonization strategies and to respond to the major needs of industrialized recycling.

Research on the Formation Mechanism for the Co-agglomeration of Producer Services and Manufacturing in the Guangdong- Hong Kong-Macao Greater Bay Area

The Guangdong-Hong Kong-Macao Greater Bay Area is witnessing a surge in economic development,showcasing robust resilience in the co-agglomeration of producer services and manufacturing industries,along with the increasingly evident impact generated by such co-agglomeration.Based on the panel data collected from ten cities in the Guangdong-Hong Kong-Macao Greater Bay Area(excluding Zhaoqing)spanning from 2010 to 2020,we examined the formation mechanism for industrial co-agglomeration in the area from three dimensions:industrial correlation,spatial correlation,and policy guidance.Our analysis was based on a vertical correlation model and was validated using the seemingly unrelated regressions(SUR)method.The findings are as follows:(a)There currently exists no spatial correlation between the producer services and manufacturing sectors in the area,and the correlation between the two remains limited to the former providing specialized services to the latter.(b)Policy guidance has a positive impact on the location selection of industries within the area.By implementing a comprehensive range of favorable policies,local governments can provide effective and scientifically guided recommendations regarding the location of producer services and manufacturing sectors.Therefore,it is crucial to foster the collaboration between producer services and manufacturing sectors and further enhance the co-agglomeration between the two sectors.In addition,the government authorities should also strive to enhance its economic governance capacity,thereby facilitating the formation of such co-agglomeration.

Strategies and Suggestions for the Development of Mechanized Rapeseed Production in Sichuan

Mechanization is the future direction of rapeseed production in Sichuan. A series of technology tests for rapeseed mechanized production have been carried out in terms of variety selection, key agronomic measures and machinery in the main production area of Sichuan in recent years. In the research, the agronomic techniques, including variety selection for mechanical production, key agronomic measures and mechanical harvesting were analyzed. Based on the present condi- tions, strategy and suggestions for the development of mechanized rapeseed produc- tion in Sichuan also were presented.

A Study on the Current Situation, Challenges and Value-guiding Strategies of the Cultural Communication of Chinese Online Micro-Short Dramas

This paper discusses in depth the current situation of cultural communication of Chinese online micro-short dramas,the challenges they face,and the strategies for guiding values.With the rapid development of Internet technology,online micro-short dramas,as an emerging form of cultural communication,have rapidly risen to become an important force in the field of cultural communication in China with their short,concise,diversified contents and rapid dissemination.This paper first defines the definition and characteristics of online microshort dramas,and analyzes their current situation in cultural communication,including the significant improvement in quantity and quality,rich and diversified content themes,and a wide range of audience groups.However,the rapid development of online microshorts also faces challenges such as insufficient content innovation,serious homogenization,unsound regulatory mechanism,and ambiguous value orientation.To address these issues,this paper proposes value-oriented strategies including strengthening policy guidance and supervision,enhancing creators'quality and sense of responsibility,optimizing platform content ecology and recommendation mechanism,strengthening audience education and guidance,and promoting the deep integration of industry,academia,research and application.Through case studies and theoretical discussions,this paper aims to provide effective value guidance paths for the cultural dissemination of online micro-dramas,and to promote their development in a more healthy and positive direction.

How to Deal with the Trade-off between Development and Decarbonization for Rural Logistics in China?Evidence from Jiangsu

Rural logistics faces a dilemma between development and high carbon emissions in China.We assess the tension between rural logistics development and carbon emissions from the perspective of policy guidance by modeling a rural logistics system using Jiangsu’s data.We simulate the development trend of Jiangsu rural logistics under carbon abatement policies from 2021–2030,with a focus on promoting its development while simultaneously reducing carbon emissions at a minimal cost.The findings show that rural logistics will move towards high carbon emissions without a carbon abatement policy,while the huge tax pressure of carbon reduction policies reduces the profitability of rural logistics,leading to a trade-off between development and decarbonization.From the perspective of implementation timing and manner of carbon abatement policies implementation,we propose a pathway for securing the profitability of rural logistics and resolving the trade-off.
