We observe that under the hydrothermal growth a starting stoichiometric mixture of cationic precursor's leads to a bi-phasic constitution comprising of defect-spinel CCO and a small quantity of CuO. Use of the excess but optimum cobalt in the precursor mix leads to single phase defect-spinel. We have carefully examined the implications of off-stoichiometry for different cases of interest (including the case of Cu-excess) for morphology, microstructure, the physical/electrochemical properties, and the evolution of the Li-ion battery anode under cycling for different active materials loading. In case of optimum Cu excess based CCO renders an impressive performance as Li-ion battery anode with high rate performance, 836 mAh g−1 and 757 mAh g−1 at 1.25C and 2.5C, respectively, and good cycling stability. © 2016 Elsevier Ltd</p>1 aBhardwaj, M.1 aSuryawanshi, A.1 aFernandes, R.1 aTonda, S.1 aBanerjee, A.1 aKothari, D.1 aOgale, S.  uhttps://library.ncl.res.in/content/cuco2o4-nanowall-morphology-li-ion-battery-anode-enhancing-electrochemical-performance
