查询词典 oxalate

This invention discloses one lithium ion battery anode materials, which is made by following steps: a, mixing lithium salt, microcosmic salt and ferrous oxalate for grinding with mole proportion as one to one to one; after drying under nitrogen gas protection in 300-400DEG C for heating for five to eight hours; b, adding addictive agent into the mixture with weight proportion as3-10:1; c, bursting the mixture gas under inertia gas protection under temperature of 500-800DEG C for 10 to 24 hours; d, adding the product into crucible with active carbon 10 to 40 g and adjusting the microwave frequency into 140 to 700 W with control time as 1 to 14 minutes.

本发明公开了一种锂离子电池正极材料，由70-90wt％的LiFePO 4 和10-30wt％的碳组成，按照以下步骤制备：(1)将锂盐、磷盐和草酸亚铁混合球磨，所述锂、铁和磷元素的摩尔比为1∶1∶1，干燥后在氮气保护下300～400℃预热5～8小时；(2)在上述的混合物中加入添加剂，所述混合物与添加剂的重量比为3～10∶1；(3)将步骤(2)得到的混合物在惰性气体保护下，进行焙烧，焙烧温度为500～800℃，焙烧时间为10～24小时；(4)将焙烧后的产物压片，放入装有活性炭10～40g的坩锅，再将坩锅放入微波炉中，微波功率调至140～700W，控制时间为1～14分钟。
