Electrochemical performance of a tin electrodeposit with a multi-layered structure for Li-ion batteries

ABSTRACT
The electrochemical performance of a tin electrode synthesized on copper foil by electrodeposition in a pyrophosphate-based bath is examined by modifying its morphology via controlling the cathodic current density. As this current density increases, the morphology of the tin electrodeposit changes from a smooth and compact structure to a microscopically multi-layered structure with open spaces between adjacent layers. The porosity of the multi-layered tin electrode is more than 60% of its volume. The cycle performance and coulombic efficiency of the multi-layered tin electrode are higher than those of the smooth tin electrode, primarily due to the buffering effects of the open spaces between the layers against the volume expansion of the tin anode during cycling.
嗯,就是上面这一堆了!

锂电池多层结构镀锡的电化学性能研究

摘要:
在焦磷酸为基质的镀锡铜叶构成的电极可以通过控制印机电路密度来改变其形态,进而检验其的电化学性能。随着电路密度的增加,镀锡电极的邢台从平面、压缩状态,变成了精细的多层结构,并且再起相邻的层与层之间具有开放的空间。这种多层结构的电极的孔洞体膨胀要比其体积多出60%。多层结构循环特性和库伦效率要比那些平面状态的高,这主要是由于多层结构的层空间存在的缓冲效应克服了循化过程中锡阳电极的体膨胀。
