Although
silicon is a promising anode active material due to its extremely
high specific capacity, one of its primary disadvantages is that
large volume changes (>400%)3 can lead to rapid pulverization
of Si particles and loss of capacity during cycling. A common
approach to improving the cycling performance of silicon-based
anodes is to use nanostructured silicon,1,4−7 but a drawback to
this approach is that the high surface area of nanostructured
materials significantly increases solid electrolyte interphase
(SEI) formation on the first cycle
