摘　　要：风、光等新能源分布式发电受天气和气候的影响出现间隙性和随机性等使得发电的不稳定缺点正成为阻碍其深度发展的重要障碍。储能技术的发展和应用,打破了风电、光伏发电等的接入和消纳瓶颈问题。介绍了应用于储能系统的主要化学储能电池:铅酸电池、液流电池、钠硫电池和锂电池的技术发展、组成结构和储能原理,详细对比了各种电池的性能及特点,特别对能量密度、功率密度和功率等级进行介绍,这是储能系统电池元件选择的关键,最后对储能电池的应用和发展作了展望。Wind, PV and other renewable energy distributed generation （DG） are intermittent and random generation by the occurring weather and climate, and its unstability is the major obstacle to its extensive development. The development and application of energy storage technology solves the problem of connection of the wind power and photovoltaic power generation to the grid and eliminates the consumption problem. The technology development, structure and principle of energy storage of primary chemical storage batteries including lead acid battery, flow battery, sodium sulfur battery and lithium battery were described, their performance and characteristics were compared, and especially, their energy density, power density and power level were introduced in detail, which was the key to select the battery energy storage system. Finally, the future application and development of energy storage batteries was proposed.
