看了崔屹Nano Today的文献《Designing nanostructured Si anodes for high energy lithium ion batteries》，P417里有一句话是这样的，我没太能理解是什么意思。请各位锂离子电池的大神解释一下！金币不多，真心求解！
In other words, for smaller structures, the stress-relief volume accompanying crack growth is not significant enough to overcome the surface energy penalty associated with the crack growth.
