Abstract: 본 발명은 바나듐 오산화물을 이용하여 리튬 2차전지용 양극판을 제조하는 방법에 관한 것으로, H
2 O
2 가 포함된 수용액에 바나듐 오산화물을 용해시켜 젤(gel)을 형성함으로서 결착제를 사용하지 않거나 적은 양을 사용하더라도 금속 지지체 상에 도포가 가능하다.
H
2 O
2 가 함유된 수용액에 적당량의 바나듐 오산화물을 가하면 산소가스를 발생시키면서 투명한 수용액을 형성한다. 형성된 수용액은 시간이 지나면 점성을 가지는 젤(gel) 상태로 변하게 된다. 젤(gel)이 형성되는 과정에서 도전제와 소량의 바인더를 혼합하면 활물질인 바나듐 오산화물과 균일하게 혼합된 슬러리가 만들어진다. 이와 같이 만들어진 슬러리는 높은 점성을 가지므로 소량의 바인더를 사용하더라도 금속 지지대에 도포가 가능하다. 또한, 젤(gel)이 형성되는 과정에서 도전제, 바인더 등의 첨가물을 혼합하므로 분말을 혼합하는 방식보다 쉽고 균일하게 혼합이 이루어져 첨가물의 사용량을 줄일 수 있으며, n-메틸 피롤리돈(NMP)나 아세톤과 같은 인체에 유해한 용매를 사용하지 않으므로 환경 친화적이다.Abstract translation: 本发明涉及使用氧化钒制造二次锂电池用阴极电极的方法。 将氧化钒溶于含有H 2 O 2的水溶液中以形成凝胶。 因此，即使不使用粘合剂或者使用少量的粘合剂，也可以将凝胶施加到金属载体上。 如果将含有足量的氧化钒放入含水溶液中。 在产生氧气的同时形成透明的水溶液。 然后将水溶液随时间变化为粘度的凝胶状态。 在形成凝胶的过程中加入少量导电材料和粘合剂，然后与作为活性材料的氧化钒均匀混合，从而形成浆料。 由于浆料具有高粘度，所以即使用少量的粘合剂也可以将其施加到金属载体上。 此外，作为导电材料，粘合剂等在形成凝胶的过程中混合，与混合粉末的方法相比容易且均匀地混合。 因此，可以减少添加剂材料的使用。 此外，本发明是环境友好的，因为不使用对人体有害的溶剂如N-甲基吡咯烷酮（NMP），丙酮等。
