We have made three - dimension electric conduct grid by hand and we have successfully used it as anode grid in lead - acid battery . this kind of three - dimension electric conduct grid can improve the utilization of pam by 7 - 9 % in different discharge current density and can reduce the plate electrochemical impedance to one tenth of the normal plate . also this kind of grid can improve the marginal reaction current density in a certain degree 我们通过手工制作了三维导电体板栅，并成功的应用于电池的正极作为正极的板栅，这种三维导电体板栅能够在各种不同的放电电流密度下提高正极活性物质利用率7 9 ，能够使电池正极板的电化学阻抗降低到普通板栅的1 10左右，使正极板的极哈尔滨j _程大学硕十学位论文限反应电流密度略有所提高，但是这种板栅的耐腐蚀性能很不理想，使得所制作电池的寿命很短。
