Abstract(in English) | The development of various battery technologies used for the load-leveling system have been competed among many organizations concerned. Recently, the service life of a valve regulated lead acid battery (VRLAB) has reached the same level of the so-called advanced batteries. Under such circumstance, we have been focusing on the improvement of the service life of VRLAB by applying and utilizing the corrosion protection technology on positive electrode, the formula of negative electrode additives, a suitable separator for cyclic use and the optimized charge condition obtained from development of the VRLAB for electric vehicle and out of our fundamental studies. In this article, we would like to give a report on the achievement we have made on the VRLAB (50Ah/10HR), which has been under development reached 7000 cycles (1CA discharge pattern, DOD 70%) that greatly exceed 4000 cycles of our original target. |
