[求助] Nano Lett. 中几个关键概念求助（锂电）

1、
The nanowire or nanorod morphology not only has a large surface-to-volume ratio but also provides efficient one-dimensional electron transport pathways and facile strain relaxation during battery charge and discharge.
这里的在充放电过程中 facile strain relaxation指的是什么？

2、
We have to consider, however, that usually a battery pack is assembled with a
certain amount of extra capacity at the cathode to compensate irreversible anode reactions taking place during the first cycle. In this case, it is an advantage to use the charge excess instead of loading more material at the cathode.
这里的use the charge excess 是什么意思？
