Abstract (en)

[origin: WO9950922A1] An electrode includes an electrically conductive matrix containing a disulfide group, wherein an S-S bond of the disulfide group is cleaved by electrochemical reduction and reformed by electrochemical oxidation. A plurality of carbon nanotubes is dispersed in the electrically conductive matrix. The electrode can be used as a cathode of a lithium battery.
