With the rapid development of electric vehicles, power battery market demand rapidly expanding, battery scrap and recycling has become a serious problem. Based on the analysis and forecast of waste battery amount from 2014 to 2024, the paper researched the future theoretical metal recycling amount of power battery in China. Life cycle assessment method is used to establish a waste lithium ion batteries and nickel-metal hydride batteries recycling process of environmental impact assessment model, and the data lists of recycling process are built. The environmental impact load are analyzed and compared. Through the establishment of economic analysis model of waste battery recycling process, the economic performance is quantified. To develop the recycling of waste power battery mode, laws, regulations and relevant technical standards for China[, this paper provide the method reference and data support.

Green performance assessment of power battery is a whole life cycle process, which integrates Environment (E), Resource (R), Technology (T) and Cost (C) objectives considered as evaluation of multi-objective and multi-stage. According to definition of Green Product, the assessment model of multi-objective and multi-stage for power battery was built. The green utility function is proposed, by which the evaluation data of indices are changed uniformly into range of (0, 1) according to the assessment standard initialized as 0.5. The synthesis calculation method is given, which remains all the messages in the assessment. Finally, the green performance comparison between lithium-ion battery and nickel metal hydride battery proves the assessment method and process.

Now, the renewable resources recycling system do not include the traction battery recycling in China, and there are also some problems in the existed recycling system. In the field of resource recycling, especially for battery recycling, the management system, laws and regulations, and technical standards have been behind of the developed countries. This paper from producers self-establish the recycling system, producers alliance self-establish the recycling system and producers recycling business commission mode to discuss the recycling model for traction battery.
