本发明属于新能源领域的电池技术， 涉及一种适应于调节电网的波 峰、 波谷及作为电动汽车移动电源的带式储能电池。 背景技术  The invention belongs to the battery technology in the field of new energy, and relates to a band-type energy storage battery adapted to adjust the peaks and troughs of the power grid and as a mobile power source for electric vehicles. Background technique
液流电池是一种大型储能装置，其基本工作原理为电池的正负极或某 一极活性物质为液态流体氧化还原电对。由于液流电池能够将能量转化到 电解液中分别进行存储， 因为具有超大规模存储能量的优势， 由于这种特 点液流电池适合风能、太阳能等新能源发电的储能技术。在液流电池中目 前以全钒液流电池最具发展潜力。 然而， 在全液流电池中， 钒电池正极液 中的五价钒在静置或温度高于 45 °C的情况下易析出五氧化二钒沉淀，析出 的沉淀堵塞流道， 包覆碳毡纤维， 恶化电堆性能， 直至电堆^艮废。 且在该 电池中石墨极板容易被正极液刻蚀，而电堆在长时间运行过程中电解液温 度很容易超过 45°C，如果用户操作不当，一次充电就能让石墨板完全刻蚀， 电堆只能报废。 同时该电池还存在放电电流密度低，体积比功率密度低的 特点。 发明内容  The flow battery is a large-scale energy storage device. The basic working principle is that the positive and negative electrodes of the battery or the active material of a certain pole is a liquid fluid redox couple. Since the flow battery can convert the energy into the electrolyte for storage separately, because of the advantages of ultra-large-scale storage energy, the special-purpose flow battery is suitable for energy storage technology of new energy generation such as wind energy and solar energy. In the flow battery, the current development potential of the all-vanadium flow battery is the most potential. However, in the full-flow battery, the pentavalent vanadium in the vanadium battery positive solution is likely to precipitate vanadium pentoxide precipitate when it is still at a temperature of 45 ° C or higher, and the precipitated precipitate blocks the flow path and coats the carbon felt. Fiber, deteriorate the performance of the stack until the stack is destroyed. Moreover, in the battery, the graphite plate is easily etched by the positive electrode liquid, and the temperature of the electrolyte easily exceeds 45 ° C during long-term operation. If the user operates improperly, the graphite plate can be completely etched by one charge. The stack can only be scrapped. At the same time, the battery also has the characteristics of low discharge current density and low volume specific power density. Summary of the invention
