Corrigendum to “Facile fabrication of CuO/Ag₂Se nanosized composite via hydrothermal approach for the electrochemical energy conversion system” [Volume 56, Part A, 1 December 2022, 105929] (Journal of Energy Storage (2022) 56(PA), (S2352152X2201917X), (10.1016/j.est.2022.105929))

The authors regret < We have observed that in the spectrum of XRD, presented in Figs. 2 and 7d, there was an error while processing and graphing, leading to the deletion of a significant point that cause appearance of discontinuous spectrum. We apologize as this has been overlooked in the submission process, due to student error. We have now corrected the Figure and no baseline correction or smoothening operations applied. Fig. 2.
