应用在储能系统的退役动力电池梯次利用分析

Step utilization analysis of retired power battery applied in energy storage system

新能源动力汽车经过10余年的迅速发展,我国目前已经成为该领域的产销大国。锂离子动力电池及其管理系统是新能源动力汽车的三大核心部件之一,而退役电池的处理方式成为难题之一。储能系统的应用是清洁能源利用的核心环节,在全部的电化学储能装机类型中,锂电池是目前电化学储能的主流模式,占比高达90%以上。由此,退役电池在储能系统中的应用是重要的研究方向,其拆解、电芯筛选也成为关键课题。

After more than 10 years of rapid development of new energy powered vehicles,China has become a big producer and marketing country in this field.Lithium-ion power battery and its management system are one of the three core components of new energy power vehicles,and the disposal of decommissioned batteries has become one of the difficult problems.The application of energy storage system is the core link of clean energy utilization.In all types of electrochemical energy storage installations,lithium battery is the mainstream mode of electrochemical energy storage,accounting for more than 90%.Therefore,the application of decommissioned battery in energy storage system is an important research direction,and its disassembly and cell screening have also become key topics.
