New energy vehicles are regarded as the development direction of future vehicles,but the recycling of its key components,power batteries,has received more and more attention.First of all,starting from green environmental protection concept,this paper analyzes the current situation of China's new energy vehicle power battery,expounds the importance of power battery recycling,and reveals the problems it faces,such as backward processing technology,imperfect regulations and policies.Then,combined with concrete examples,the optimization measures for these problems are discussed,such as improving recycling technology,improving relevant laws and regulations,and establishing effective policy incentive mechanisms.Finally,the importance and urgency of building a new energy vehicle power battery recycling model with green environmental protection as the core is emphasized.Through this series of research and discussion,the purpose is to provide reference and inspiration for the sustainable development of new energy vehicles.
