AGM隔板性能对密封铅酸蓄电池性能的影响

Effects of the specificity of AGM separator on the performance of sealed lead-acid batteries

介绍了超细玻璃纤维 (AGM )隔板性能对密封铅酸电池性能的影响 ,包括基重和厚度的均匀性、回弹性和压缩率、孔率和吸酸量、孔径、电阻、杂质等。表明了以下几点 :(1 )隔板的基重和厚度均匀性是影响电池容量均匀性的主要原因 ;(2 )隔板的回弹性和压缩率是电池实现紧装配的保证 ,也是电池内隔板与极板有较好紧贴效果的保证 ;(3 )隔板的孔率和吸酸量是电池容量、使用寿命和大电流放电性能的保证 ;(4 )隔板的孔径大小反映了隔板能否防止铅枝晶穿透的能力 ;(5 )隔板的电阻直接影响电池的低温启动性能和大电流放电性能 ;(6)隔板的杂质是造成电池自放电的直接原因。

Effects of the specificity of AGM separators on the performance of sealed lead-acid batteries were introduced, including the uniformity of basis weight and thickness, elasticity and compressibility, porosity and absorption, pore-size, electrical resistance, impurity, etc. Several points of view were indicated as follows: (1)The uniformity of basis weight and thickness of separator is the main factor affecting the uniformity of battery capacity; (2)The elasticity and compressibility is the warranty of realizing the battery being tightly assembled, and it is also the warranty of separator clinging to the battery plates tightly; (3)The porosity and absorption is the warranty of the performances of the battery, such as capacity, operating life and large current discharge; (4)The pore-size of separator decides whether it can prevent the lead crystal penetrating; (5)The resistance of separator affects the low-temperature start-up and the large current discharge performances of the battery; (6)The impurity of separator is the direct reason causing the battery self-discharge.
