However, because the practical cycling environment resembles the electrochemical pretreatment conditions, the remaining silica cages continued to be reduced during cycling, leading to capacity fluctuation and gradual decay. In this work, we introduce a TiO\n                    <jats:sub>2<\/jats:sub>\n                    \u2010assisted derivation strategy to regulate the formation of silicon quantum dots from silica cages.

Consequently, the mechanical integrity of the robust silica cages can be preserved over prolonged cycling.
