采用泡沫镍电极制备工艺,研制开发了20～115Ah系列电动车用方型密封镍氢动力电池,单体电池比能量达60～70Wh/kg,电池比功率大于160W/kg,12V电池组比能量达54Wh/kg,电池可在-20～50℃下工作;电池寿命仍在测试之中,该电池具有良好的过充、过放电能力。将两组120A/100Ah 密封镍氢动力电池以并联方式供电驱动电动汽车,电动汽车一次充电行驶距离可达225km,并一次充电完成北京—天津往返等城市实际路况的实车运行实验,平均时速50～80km/h,最高时速大于100km。
The nickel-hydrogen battery with a square-shaped seal of 20 ~ 115Ah series has been developed and manufactured using the nickel foam electrode. The specific energy of the single battery is 60 ~ 70Wh / kg and the specific power of the battery is more than 160W / kg. Up to 54Wh / kg, the battery can work at -20 ~ 50 ℃; the battery life is still under test, the battery has a good overcharge, over discharge capability. The two groups of 120A / 100Ah sealed NiMH batteries are powered by parallel mode to drive electric vehicles. The electric vehicles can travel up to 225km in a single charge and complete the actual vehicle running experiments of Beijing-Tianjin round-trip and other cities in real time with an average speed of 50 ~ 80km / h, the maximum speed of more than 100km.
