Abstract:Using thermal evaporation technology, Ni-CNT are grown in-situ on nickel plates as the cathode of Li-O2 batteries. This integrated electrode structure eliminates the negative impact of binders on the electrochemical performance and greatly reduces the process for preparing the lithium oxygen battery cathode. Ni-CNT exhibit excellent catalytic activity, and provide an ultrahigh discharge specific capacity of approximately 4.3 mAh cm−2 at 0.1 mA cm−2, the discharge voltage plateau is stable above 2.79 V.
