To increase the energy density of Li-ion batteries (LIBs), silicon has been widely studied due to its relative abundance and high theoretical specific capacity (∼3572 mAh g–1). However, silicon experiences drastic volume changes up to 300% associated with Li. Here, we report an in situ cross-linked...
