Abstract
Flexible lithium-ion batteries have attracted tremendous attention as a promising power source in the growing field of flexible electronic devices. CuO shows high theory specific capacity in Li-ion storage, but it also suffers poor electrochemical cycling stability arising from the low conductivity during the lithium uptaking/releasing process. In this work, we report a simple and binder free for the synthesis of flexible Cu3N/CuO thin film electrodes directly on Ni foam by magnetron sputtering method followed with annealing in air at low temperature. This method is highly effective in improving the rate capability of the 300
