battery also uses plates and electrolyte as in the flooded Pb-acid batteries. A pure form of silica is added to the electrolyte solution forming an acidic gel. As the gel dries out, cracks are formed. The cracks, when seen through a clear casing, appear identical 第二个VRLA电池根据胶凝体...
a1.铅酸蓄电池性能可靠而价廉、紧凑。平均寿命仅为2～2.5年,在寒冷气温下更短。在安全方面,铅酸蓄电池溶液可用胶体来代替。充电时放出的氢气有爆炸的危险,需用密封装置解决。它是技术最成熟的电池,为大多数的电动汽车选用,但是当其过充电、过放电时寿命会缩短。 1. lead-acid battery performance reliable and is...
