β′′-氧化铝系列产品

β″-氧化铝

Beta-氧化铝 / β″-Al2O3

β″-氧化铝 有两种不同的晶体结构:β-Al2O3(六方晶系:P63/mmc)和β″-Al2O3(菱形:R3m)。β-氧化铝和β″-氧化铝相在化学组成和离子导电层间的氧离子堆垛顺序上有所不同,β-氧化铝为Na2O·(8~11)Al2O3,β″-氧化铝为Na2O·(5~7)Al2O3,β-氧化铝是2个尖晶石堆积,β″-氧化铝是3个尖晶石堆积。β″-氧化铝由于含有较多的Na+,因此比β相的离子导电率要高。 Na-β/β″-Al2O3作为传统的钠离子导体材料广泛应用于Na/S电池以及固态钠离子电池的隔膜和电解质。

我公司与德国技术团队合作研发的β″-氧化铝系列产品填补了国内空白,工艺先进、性能卓越,目前已有B-D2和BM-D2两个级别的产品。
