作者：李美娟 沈阳蓄电池研究所 上传时间：2012/9/17 17:17:24
摘要：新开发的产品，适合于有效利用自然能源和夜间电力的长寿命电力储备用阀控式铅酸蓄电池。（1）正极板采用耐腐蚀的板栅合金，减小了板栅的腐蚀变形，另外，选用高密度的活物质铅膏；（2）为提高负极充电性能，采用石墨添加剂；（3）新开发的产品，电池组在使用时可通过金属柜结构有效地控制电池温度上升及电池间的温差，使循环寿命达4500次（25oC、70%放电量），充放电效率87%，电池性能优于传统同类产品。该产品在相关的电力储备系统经过2年零6个月的实车运行试验被确认为运行良好，实用毫无问题。
叙词：储能 阀控式铅蓄电池 长寿命 Abstract：We developed new designed VRLA(Valve-Regulated LeadAcid)batteries LL-S series with long cycle life for power storage system to meet the significant utilization of natural energy and nighttime electric power .The cycle life of this new designed batteries is much improved by the adoption of the specifications as follows.(1)Positive plates with grid of high corrosion resistance alloy ,designed to reduce deformation and high density active material,(2)Negative plates using new carbon for increasing charge performance,(3)New metal frame structure for decreasing of temperature rise and dispersion of cell temperature as used a set of battery .It has excellent characteristic on cycle life performance of 4,500 cycles and charge-discharge efficiency of 87% .In demonstration test by runnimg for over 2 and half years, it is confirmed that there are no problems in use of the system . Keyword：Energy storage, Valve regulated lead acid battery, Long duration
