牵引用阀控式铅酸电池的研发

Research and development of valve-regulated lead-acid battery for traction

在牵引用阀控式铅酸(VRLA)电池设计时,通过增加板栅质量提高耐腐蚀性,使腐蚀周期延缓了约5个月;减小横筋条间距和倒三角截面形状,阻碍活性物质脱落;采用正极活性物质冗余设计,延长软化周期和电池使用寿命。电池槽侧面采用深藏式和拱形加强筋结构设计,防止电池在高温条件下长时间使用导致的侧面鼓胀。

In the design of valve-regulated lead-acid(VRLA)battery for traction,the corrosion cycle was delayed about 5 months by increasing the quality of grid to improve the corrosion resistance;reducing the spacing of transverse bars and the shape of inverted triangle section could prevent the active substance from falling off;redundancy design of positive active material was adopted to extend softening cycle and battery life.The side of the battery tank was designed with deep hidden and arch stiffeners structure to prevent the side bulging caused by long-term use of the battery at high temperature.
