目前我国铁路客车蓄电池基本上以管状阳片—涂粉式阴片铅酸蓄电池为主。旧型涂粉式阳片通常易发生的膨胀、断裂、脱粉等缺陷在玻璃纤维管状阳片上大为减少。因此,在开始推行本型蓄电池时,认为管状阳片较涂粉式阳片寿命率能延长30%。然而经过十余年来运用实践,统计其平均寿命率,发现并不比涂粉式为高,且因本型极片的难以焊修,故平均寿命反较涂粉式为低。从全路
At present, China’s railway passenger car battery is basically a tube-shaped tablets - coated powder-based lead-acid storage battery-based. The old powder coating-type tablets are usually prone to expansion, fracture, powder and other defects in the glass fiber tube-shaped anode greatly reduced. Therefore, at the beginning of the implementation of this type of battery, that the tube-shaped film than powder-coated film slice life-span can be extended by 30%. However, after more than ten years of using the practice, the average life expectancy was calculated and found to be no higher than the dusting type, and the average life expectancy was inversely lower than that of the dusting type due to the difficulty of welding of the current type of pole piece.
