Abstract

본 발명은 휴대용 전원으로 많이 사용되고 있는 밀폐형 축전지의 고율 충방전 특성을 향상시키는 방법에 관한 것으로, 밀폐형 축전지에서 이온 전도도와 가스 재결합 정도를 조금씩 양보하는 선에서 격리판의 전해액 함침 정도를 결정했던 것을, 밀폐형 축전지 내의 양극판 후면과 음극판 후면 사이에 산소 가스 이동용의 새로운 격리판을 두어, 기존의 격리판이 담당하던 기능을 새로운 격리판과 분담하게 함으로써, 이온 전도도를 높여주면서(용액 저항을 감소시키면서) 산소 가스 이동도 원활하게 될 수 있도록 하여 밀페형 축전지에서의 고율 충방전 특성을 향상시켰다.The present invention relates to a method of improving the high rate charge / discharge characteristics of a sealed battery, which is widely used as a portable power source, wherein the degree of electrolyte impregnation of the separator is determined in a manner of yielding ionic conductivity and gas recombination degree little by little in the sealed battery. A new separator for the transfer of oxygen gas is placed between the positive and negative electrode plates in a sealed battery, allowing the function of the existing separator to be shared with the new separator, thereby increasing ionic conductivity (reducing solution resistance). The high rate charge / discharge characteristics of the sealed battery were improved by making the movement smooth.
