摘　　要：储能技术是解决新能源波动性、间歇性的有效手段,是新型电力系统发展的重要支撑。随着新能源汽车产业的带动以及政策的支持,以磷酸铁锂为主的电化学储能快速发展,形成万亿级市场。本文主要围绕磷酸铁锂电池电化学特性,分析了磷酸铁锂电池使用寿命下降的原理,以及影响磷酸铁锂电池循环寿命和日历寿命的因素。同时以目前商业应用的磷酸铁锂储能技术参数为参考,测算了磷酸铁锂储能在电网侧、用户侧应用的经济性。测算结果表明,在大多数应用场景下,磷酸铁锂储能不具备经济效益。最后,本文结合电力市场提出了适合磷酸铁锂储能商业化发展的市场与盈利机制。Energy storage technology is an effective means to solve the volatility and intermittency of renewable energy power,and it is important for the development of new power systems.With the policy support,and the promoting effect by the new energy vehicle industry,electrochemical energy storage which mainly based on lithium iron phosphate has developed rapidly,forming a trillion market.In this paper,the aging and degradation mechanism,as well as the influences for cycle life and calendar life degradation of the lithium iron phosphate battery have been discussed.Meanwhile,with current commercial lithium iron phosphate batterie’s parameters as references,the economic benefits of lithium iron phosphate energy storage on the power grid side and user side have been calculated,which resulted that in majority application scenarios,lithium iron phosphate energy storage is uneconomical.At last,based on the properties of power market,several suitable suggestions for the commercial development of lithium iron phosphate energy storage are proposed.
