Interaction of SCCO 2 with Si produces a continuous SiO x layer, which can buffer Si volume change during lithiation\/delithiation. In addition, a conformal carbon film is deposited around the Si@SiO x core. Compared to the carbon film produced via a conventional wet\u2010chemical method, the SCCO 2 \u2010deposited carbon has significantly fewer oxygen\u2010containing functional groups and thus higher electronic conductivity. Three types of carbon precursors, namely, glucose, sucrose, and citric acid, in the SCCO 2 syntheses are compared. An eco\u2010friendly, cost\u2010effective, and scalable SCCO 2 process is thus developed for the single\u2010step production of a unique Si@SiO x @C anode for Li\u2010ion batteries. The sample prepared using the glucose precursor shows the highest tap density, the lowest charge transfer resistance, and the best Li + transport kinetics among the electrodes, resulting in a high specific capacity of 918 mAh g \u22121 at 5 A g \u22121 . After 300 charge\u2013discharge cycles, the electrode retains its integrity and the accumulation of the solid electrolyte interphase is low. The great potential of the proposed SCCO 2 synthesis and composite anode for Li\u2010ion battery applications is demonstrated.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/adfm.202104135 Authors: Rahmandhika Firdauzha Hary Hernandha, Purna Chandra Rath, B.
