Nanoporous Particles Behind Boost to ASSLIBs Cycle Stability

Stress relaxation due to structural fluctuations in silicon (Si) is critical for its application in lithium-ion batteries (LIBs). In an article published in the Journal of the Electrochemical Society, mesoporous silica (SiO2) spheres were reduced using magnesium silicide (Mg2Si) to achieve nanoporous Si particles. The fabricated Si particles were applied as anode material for all-solid-state LIBs.
