route [23]. After heating at 120 C for 2 days and then sintering at 750 C for 4 h, these plates were cut into small sections, which were then sintered at 900 C for 12 h to decrease the sizes of the voids. The 1.5 mm thick plates were infiltrated with nickel (ca. 100 lm) using the previously describe

Abstract
This study demonstrates the formation of a flexible and free‐standing carbon nanotube–copper oxide–poly(vinylidene fluoride) (CNT–Cu~2~O–PVDF) nanocomposite and its application as an electrode‐separator material for Li‐ion batteries. Binder‐free hybrid electrodes are obtained by conformally coating CNTs with Cu~2~O via electrodeposition and then embedding the resulting architecture into a porous poly(vinylidene fluoride‐hexafluoropropylene) PVDF‐HFP–SiO~2~ polymer electrolyte membrane. The synergistic presence of high‐capacity transition metal oxides and conductive CNTs results in twice the reversible areal capacity of 2.3 mAh cm^−2^ as compared to 1.2 mAh cm^−2^ for pure CNTs.
