Three‐Dimensional Porous Silicon Particles for Use in High‐Performance Lithium Secondary Batteries

Kim, Hyunjung, Han, Byunghee, Choo, Jaebum, Cho, Jaephil·2008·Angewandte Chemie International Edition

Abstract

Particle-larly good! Thermal annealing and etching of physical composite butyl-capped Si gels and SiO2 nanoparticles at 900 °C under an Ar atmosphere is a versatile method for the formation of 3D porous bulk Si particles (see picture). Complete etching of the SiO2 from the SiO2/carbon-coated Si (c-Si) composite results in the retention of the remaining c-Si as a highly porous but interconnected structure, which preserves the starting morphology.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
