摘　　要：阀控式密封铅蓄电池（ＶＲＬＡ）电流放电初期出现的电压降主要是由电池欧姆内阻引起的。板栅和极柱连接件的电阻是电池欧姆内阻的主要成分。合理设计板栅结构、提高正板栅铅钙合金中的锡含量和负极活性物质中的碳含量，将会有利于提高电池的低温起动力。The voltage drop occurring at the beginning of discharging for VRLA batteries is mainly caused by ohmic internal resistance of the batteries. The resistances of grids and connecting parts are the main compo-nents of the internal resistance. It has been shown that the starting ability at low temperature of VRLA batter-ies can be improved by adopting the following measures: 1) reasonable design of grid construction; 2) in-crease of tin content in the positive grid alloy (Pb/Ca) and 3) by addition of carbon in the negative active material.
