The hierarchical porous structure is productive in mitigating the swelling and maintaining structural integrity. A number of particles were similarly checked and the typical structure swelling is ~30%, which is 1/ten full article the expansion of bulk Si particles (Supplementary Fig.18d–f and Supplementary Movie2). In case of [email protected]@C, the in-situ particle swelling measurement showed that a standard [email protected]@C sphere at full lithiation has a volume expansion of ~44% (Fig.2c–f and Supplementary Movie3). This array of properties makes silicone polymers very valuable. Silicone polymers are used in insulation, cookware, higher temperature lubricants, healthcare equipment, sealants, adhesives, and even as an option...
