Research On Network Construction Of Different Recycling Modes Of Power Battery Under The Scene Of Echelon Utilization

With the growth of sales of new energy vehicles,society pay more attention to the recycling of power batteries.Power batteries contain a certain number of precious metals and harmful materials that may cause environmental pollution.Unconventional recycling and process will lead to waste of resources and environmental pollution.However,the power battery recycling industry in China started late and is still in a state of disorderly operation,as a result,the network has not been formed in China.At the same time,there are different recycling subjects and diversified recycling channels in the power battery recycling market,thus forming different recycling modes.The operation flow of power battery recycling is different under recycling modes,so the appropriate recycling network should be built according to different recycling modes.Refer to the mature power battery recycling mode of foreign countries,and according to the provisions of power battery recycling in our country,this paper puts forward three modes which are fitting for different recycling subjects,manufacturer recycling mode,third-party recycling mode and alliance recycling mode.The processes of different recovery modes are analyzed for network construction.Secondly,the grey prediction theory and market supply A model are used to predict the total amount of decommissioned power batteries in Beijing-Tianjin-Hebei region,and the feasibility of alliance recycling mode is verified based on cooperative game theory.Finally,the corresponding two-layer location-path model is established for different recovery processes,genetic algorithm and ant colony algorithm are used to solve the upper and lower-layer model,and starting from the two goals of optimal cost and optimal carbon emissions,combined with large and small-scale cases to analyze the cost and carbon emissions in different recovery scenarios.Through the analysis of the cost and carbon emissions,the following conclusions are drawn: 1)When the recovery network is built with the goal of cost optimization,under each recovery mode,the government or the market can influence the carbon emissions in the recovery network by adjusting the carbon emission price.Carbon emissions decrease with the increase of carbon emission prices,transportation costs and carbon costs increase with the increase of carbon emission prices.2)When taking the optimal carbon emission as the goal,under each recovery mode,the transportation cost and carbon emissions do not increase or decrease continuously with the change of the operating vehicles in the network,but there are reasonable values that can optimize the transportation cost and carbon cost in the network.3)Whether it is aimed at the optimal cost or the optimal carbon emissions,curtailing the distribution cycle will increase the cost when the recovery efficiency is low,and when the recovery efficiency is increased to a certain extent,curtailing the distribution cycle will reduce the cost.4)When the recovery efficiency of the manufacturer is low,the unit cost and carbon emissions of manufacturer are higher than the alliance recovery mode.Therefore,manufacturer should choose to work with the third-party recycling enterprises to build power battery recycling network.When the recycling efficiency of the manufacturer is improved to a certain extent,choosing to build a power battery recycling network alone can further reduce the cost and carbon emissions.This paper studies the construction of power battery recycling network under the background of echelon utilization.On the one hand,according to the development situation of power battery recycling industry in China,combined with relevant policies,different recycling models are put forward from the aspects of recycling subjects,which enriches the research results of power battery recycling model.On the other hand,from the point of view of cost and carbon emissions,taking the actual case of Beijing-TianjinHebei as the background,this paper studies the facility location and path allocation of recycling networks under different recovery modes,and from the perspective of manufacturers,the optimal decisions in different decision-making objectives,different recovery efficiency and different distribution cycles are analyzed,which provides a certain reference value for manufacturers with power battery recycling business in Beijing-Tianjin-Hebei region.This paper contains 41 pictures,24 tables and 95 references.
