| 摘 要： | 进一步研究在加载及无加载条件下多孔Ni电极在熔融盐中进行原位氧化/锂化时,电极厚度随时间的变化.应用SEM表征不同运行时间后多孔Ni样品的表面形态,用原子吸收光谱(AAS)测定熔盐中溶解的镍离子浓度.结果表明,负载条件下多孔镍在融盐中原位氧化/锂化时,镍离子溶出现象严重,即使无负载条件下,多孔镍在进行原位氧化/锂化过程中,仍有相当量的镍离子溶出并进入熔融碳酸盐电解质中.

| Abstract: | Based on the previous work, the deformation of porous nickel with time during the oxidation/lithiation in molten carbonates at 923 K under mix atmospheres was measured, under loading and without loading, respectively. The morphology of nickel samples after testing for different time was characterized by SEM. And the corresponding concentration of nickel ions dissolving in molten carbonates was detected by Atomic Adsorption Spectrometry(ABS). The results indicate that there was a severe dissolution of nickel during the oxidation/lithiation of porous nickel under loading condition, in addition, even if without loading, the dissolution of nickel from porous nickel was still obvious. |
