原始语种摘要: Abstract(#br)The electrochemical behavior of a SiO x –graphite composite anode with a diamond-like carbon (DLC)–Cr double-layer coating and employed in a Li-ion secondary cell was studied to determine whether the coating improved the electrochemical characteristics of SiO x . The DLC layer was coated through plasma-enhanced chemical vapor deposition, and the Cr layer was formed by physical vapor deposition. The formation of the coating layer was confirmed by transmission electron microscopy, Raman spectroscopy, and electron microprobe analysis. The charge capacity of a coated-anode cell (591mA·h·g −1 ) was found to be higher than that of a bare-anode cell (517mA·h·g −1 ) after the 1st cycle. Further, the 50th-cycle capacity retention of the...
