氟塑粘铅蓄电池正极放电性能的研究

A STUDY OF f HE DISCHARGING BEHAVIOR OF A TEFLON BONDED POSITIVE ELECTRODE IN LEAD STORAGE BATTERY

用线性电位扫描法,研究了铅蓄电池氟塑粘涂膏式正极(A)的放电性能,并与普通涂膏式电极(B)作了对比.结果证实:(A)及(B)的放电过程,都是极板孔隙内H^+离子扩散控制的.与(B)相比,(A)具有较小的容重和较大的孔率,因而扩散阻力较小,放电性能较佳.

The discharging behavior of a teflon-bonded-pasted positive electrode (A) of lead acid battery was examined with linear sweep voltametric method and compared with the ordinary pasted positive electrode(B) of a lead add battery. The results show that the processes occurring at discharging both at A and B are all controlled by the diffusion of the H+ions within the inner pores of the plates. But the discharging character of A is superior to that of B owing to the smaller, apparent density and the larger prosity and thus suffering less resistence during discharging.
