用光学悬臂梁法原位测量了电沉积纯锡和Ni-62原子%锡合金薄膜电极在循环过程中的应力。结果表明，与纯锡电极相比，Ni-62原子% Sn合金电极具有更好的循环寿命，但实际上承受的应力更大。此外，首次证实了开路期间的应力释放现象。本文论证了悬臂弯曲法对锡基电极内部应力发展、转变及发生的现象的原位研究是有效的。
The stress of the electrodeposited pure Sn and the Ni-62 atom % Sn alloy thin film electrodes during cycling was measured in situ using an optical cantilever method. The results revealed that the Ni-62 atom % Sn alloy electrode with better cycle endurance actually experiences larger stress compared to the pure Sn electrode. Furthermore, the stress-release phenomenon during the open-circuit period has been confirmed for the first time. This paper demonstrates that the cantilever bending method is effective for the in situ study of the stress development, transition, and hence the phenomena taking place within the Sn-based electrodes.
