Abstract

We found that we could manage the crystal size of active material by controlling the temperature on curing procedure which is one of the process to produce lead acid battery. The active material causes to improve initial efficiency and durability for the batteries. 3BS from the active materials after curing process is better for initial efficiency. 4BS is not good for the initial efficiency but is better than 3BS in durability by 48%. Accroding to our test results of DOD17.5% life test which is for evaluating of automobile applied ISG system, it is not suitable for flooded lead acid battery which is used for the normal automobil but it is proper to AGM lead acid battery.

납축전지 활물질 제작 공정 중 숙성공정에서 온도 제어를 통해 활물질 결정 크기를 제어할 수 있고, 생성된 활물질에 따라 초기 성능 향상, 내구성능 향상 효과를 얻을 수 있었다. 숙성반응 후 생성된 활물 중 3BS는 초기성능에는 유리 하였고, 4BS의 경우 초기 성능은 불리하였으나 내구 성능이 3BS활물질에 비해 48% 향상 되었다. 자동차용 납축전지를 ISG시스템이 적용된 자동차에 사용하기 위해 평가하는 DOD17.5% 수명시험 평가 결과, 일반 자동차 시동용으로 널리 사용하고 있는 Flooded 납축전는 적합하지 않은 것으로 확인 되었고, AGM 납축전지가 적합한 것으로 확인되었다. 그리고 3BS 활물질을 적용한 AGM 납축전지에 비해 4BS 활물질을 적용한 AGM 납축전지가 내구력이 우수하여 ISG 시스템에 적용된 자동차에 적합한 것으로 확인 되었다.
