Abstract

버턴세형의 Ni/Cd 또는 Ni/하이드리드 전장 밧데리에서 양전극 정체는 활성물질로써 고비증 밀도 (d＞3.5g/㎤)와 구형입자와 수산화니켈 분말계 물질이다.
불규칙한 입자(도면 2a)를 가지는 통상의 수산화니켈과는 대조적으로 구형 입자표면과 최대 입자 크기가 5 내지 20㎛인 비교적 범위가 좁은 입자크기 분포를 가지기 때문에 건조압착 동안에 양호한 공간 이용성을 가진다.
구형 수산화니켈계 버턴셀의 특정 용량은 통상의 양성버턴-셀전극보다 25％ 높다. 구형입자의 평균 직경 보다 적은 포어크기를 가지는 미세공 세퍼레이터는 다락-회로의 위험을 방지한다.
