储能用二次电池体系在风能、太阳能等可再生能源发电、智能电网建设等方面有着广阔的应用前景.本文对铅酸电池、钠硫电池、液流电池和锂离子电池的工作原理、特点、国内外研究现状、应用情况及发展趋势进行了综述,提出了制约储能电池发展瓶颈问题,储能电池需关注长寿命、低成本、高安全、大容量、高功率、快速充放电和环境适应性等性能指标,展望了储能二次电池体系未来的发展趋势.

Secondary batteries that store and convert electrochemical energy show broad application prospects in renewable energy systems such as wind and solar energy, and in the construction of smart grids. This paper describes the basic working principles, properties, research and development, stationary applications and advances of lead-acid, sodium sulfur, redox flow, and lithium-ion batteries. Important problems currently limiting the development of these batteries are highlighted. Energy storage batteries need to focus on the areas of long life, low cost, high safety, high capacity, high power, fast charging/discharging and environmental adaptability. The future research topics are suggested.
