Being promising candidates for anodes in lithium-ion batteries (LIBs), transition metal oxide anodes utilizing the so-called conversion mechanism principle typically suffer from the severe capacity fading during the 1st cycle of lithiation-delithiation. Herein, we directly investigated these processes using an individual CuO nanowire anode and constructed a lithium ion battery (LIB) prototype within a transmission electron microscope.
