The influence of synthesis conditions on the structural and electrochemical properties of Li1.06Co0.05Cr0.1Mn1.85O4 was investigated by X-ray diffraction, scanning electron microscopy and charge-discharge experiments. The powders were well crystallized and with a narrow particle size distribution and regular morphology about 60 nm. Electrochemical performances indicated that Li1.06Co0.05Cr0.1Mn1.85O4 delivered a high capacity of 191 mAh·g-1 at 14th cycle due to additional 3 V (vs Li) plateau, 145 mAh·g-1 at 22st cycle. The results show that there are two pairs of voltammetric wave (centered at 4 V (vs Li)) and a pairs of voltammetric wave (centered at 3 V (vs Li)), indicating an excellent reversibility.展开更多
巴西农业部暂停两批次疫苗销售近期,巴西农业部下令暂停销售及使用由Dechra巴西公司生产的016/2024和018/2024批次Excell10疫苗(抗梭菌疫苗)。此前,巴西东北部五个州接种该疫苗的牛、绵羊和山羊等家养牲畜出现大量死亡现象。数百牲畜死...巴西农业部暂停两批次疫苗销售近期,巴西农业部下令暂停销售及使用由Dechra巴西公司生产的016/2024和018/2024批次Excell10疫苗(抗梭菌疫苗)。此前,巴西东北部五个州接种该疫苗的牛、绵羊和山羊等家养牲畜出现大量死亡现象。数百牲畜死亡,疑接种问题疫苗所致。巴西《圣保罗州报》报道,据各州农业办公室以及农牧业生产者报告,上个月皮奥伊州(Piauí)、北里奥格兰德州(Rio Grande do Norte)、塞尔希培州(Sergipe)、马拉尼昂州(Maranh?o)和塞阿拉州(Ceará)接种上述批次疫苗的牛、绵羊和山羊中,有500多只可能因此死亡。展开更多
