CuO/PVDF nanocomposite anode for a piezo-driven self-charging lithium battery

An integrated self-charging power cell (SCPC) is realized from a CuO/PVDF nanocomposite piezo-anode. The efficiency of the integrated SCPC is higher than that of the non-integrated SCPC. The intimate and large contact between CuO and PVDF results in an effective use of the piezoelectric field in the internal piezo-electrochemical process.
