Research On Reverse Logistics Network Of New Energy Vehicle Spent Battery Based On Emission Reduction

Driven by the global campaign against climate change,the market of new energy vehicle has boomed across the world in recent years.Nonetheless,a huge amount of batteries will soon reach their end-of-life.Lithium-ion batteries are currently the most popular type of batteries in new energy vehicles,and how to recycle them to reduce environmental pollution has become an urgent challenge facing enterprises today.In fact,the recycling of batteries can lead to more sustainable vehicle battery production,which in turn supports the mass adoption of new energy vehicle.However,there is a lack of research on the recycling network of spent vehicle battery reverse logistics at the enterprise level,which severely impedes the implementation of secondary reusing of spent vehicle battery.Meanwhile,the design and optimization of the recycling network also has a significant impact on reduction of carbon emissions,but to date,the impact of carbon emissions on the design of the reverse logistics network has not been considered in the vehicle battery recycling network.Motivated by this,the main research contents of this article are as follows:（1）According to the reusable characteristics of new energy vehicle batteries and the relevant theories of reverse logistics,systematically analyzed the current status of the reverse logistics network of new energy vehicle spent batteries of company Y,and summarized several key issues facing the current enterprise to further determine the reverse logistics network.Furthermore,the idea and direction of reverse logistics network design were determined,which laid the foundation for the low-carbon and multi-level handling strategy of the spent vehicle battery recycling network model proposed below.（2）A new energy vehicle spent battery recycling network model is constructed in this thesis.The proposed model in this work considers three strategies to handle the spent batteries,including recycling,remanufacturing,and landfill.Spent battery are classified according the quality level of battery cells,and assigned to different processing centers in the recycling network.Moreover,to make the model more suitable for the background of the development of the global low-carbon economy,the carbon tax,as an effective energy saving and emission reduction mechanism,is also considered in the model to explore how the design of the automotive battery recycling network will be affected by the impact of the carbon tax.（3）To verify the validity of the model by applying the model to numerical cases of company Y and performing simulation analysis.The results of the study show that 5.6%decrease in total cost and 22.1%decrease CO₂ emission can be achieved if the remanufacturing infrastructure is integrated into the vehicle battery reverse logistics network.Furthermore,the sensitivity analysis shows transportation costs,carbon tax and the number of spent vehicle batteries have been identified as three major factors affecting the configuration of the recycling network.In addition,it is main direction that developing more economical recycling technology for enterprises to further reduce total cost of recycling process,and subsidies for battery recycling companies can promote the recycling of more spent batteries.Finally,combining the actual situation of the enterprise and the understanding of the cost and battery parameters is the key to the realization of a low-carbon-oriented new energy vehicle battery reverse logistics recovery network.It can be seen from this that the paper aims to provide an idea of taking into account both economics and environmental protection for automobile OEMs and industry participants by establishing a low-carbon-oriented new energy vehicle battery reverse logistics recycling network,thereby promoting the balanced management of the economy and environment of the new energy vehicle battery industry,supporting new energy vehicle battery manufacturers to reduce the environmental burden and dependence on imported fuel,and then promoting the sustainable development of the new energy vehicle market for beneficial exploration.
