Abstract:

利用电沉积法在铜箔上制备了锂电池负极材料Sn-Cu合金,研究了镀液组成对镀层铜含量的影响规律;采用X射线衍射分析,研究了不同组成Sn-Cu合金镀层热处理前后的结构.结果表明镀液中焦磷酸铜与焦磷酸钾浓度对镀层中铜含量影响显著,改变二者组成,铜含量可由20.18%(质量分数,下同)提高到58.05%;铜含量为20.18%,31.01%和58.05%的Sn-Cu合金镀层,镀态结构相同,均为Cu,Sn和-ηCu6Sn5;经过300℃以上热处理1h,Sn-Cu合金镀层发生相变,相对于镀态,析出电子化合物中铜含量增加;温度升高对铜含量为20.18%和58.05%的镀层结构影响较小,而对铜含量为31.01%的合金镀层,其组织结构向着铜含量降低的物相结构转变.
