Sintered rechargeable nickel-cadmium batteries are made with features of rigid construction,small internal resistance,long life,resistant to overcharge and discharge,wide operation temperature,high reliability,with ultra high discharge rate. Electrolyte of nickel cadmium batteries is solution of potassium hydroxide and lithium hydroxide,which keeps about high performance,high safety,life and efficiency of batteries in a certain temperature ranges. Nickel cadmium batteries for railway systems have features of low maintenance (no need of replenishing electrolyte after long-time working ), resistant to overcharge or over discharge,small self discharge,long life,high reliability. Using high purity electrolyte of potassium hydroxide to reduces the internal resistance of the nickel cadmium battery,improves the performance under low temperature,big current discharge and high temperature charge. Adopting the new valve control technology to avoid the decrease of water,prolongs the maintenance period of the nickel cadmium batteries,make sure of the performance of NiCd battery and extends the service life.
