WebSilicon can host a large amount of lithium, making it a promising electrode for high-capacity lithium-ion batteries. Recent experiments indicate that silicon experiences large plastic … WebSi, as the silicon samples have fairly large electric conductivity (see the Experimental Methods) and lithiated silicon has even larger conductivity because of its metallic-like … Web18 mrt. 2024 · Silicon (Si) is extensively used as an electrode in lithium (Li) ion batteries for its superiority in the charging capacity. However, the lithiation of Si would induce large deformation and significant stress jump across a two-phase interface in Si electrodes and might eventually lead to structure failure of batteries. tsm earning report
