Multi-wall nanotubes (MWCNTs) were added to PEO-LiClO4solid electrolytes in order to assess their enhancement of ionic conductivity. PEO-LiClO4-SiO2composite electrolytes were also manufactured for comparison. In spite of the electrical conductivity of MWCNTs, PEO-LiClO4-MWCNT composites can be sucessfiilly used as solid electrolytes, provided that additive carbon nanotubes have discontinous forms and are homogeneously distributed within the PEO-LiClO4matrix. Shortening and uniform dispersion of MWCNT were identified as crucial factors for the performance of PEO-LiClO4-MWCNT composite electrolytes. Compared with the PEO-LiClO4-SiO2composite, the addition of MWCNT to PEO-LiClO4resulted in greater enhancement in ionic conductivity. This might be attributable to enhanced amorphization by local modification of PEO chains from crystalline to disordered arrangements.
