Preparation and study of characteristics of LiCoO₂/Fe₃O₄/Li₂B₂O₄ nanocomposites as ideal active materials for electrochemical hydrogen storage

Abstract

To the best of our knowledge, for the first time, the effects of LiCoO2/Fe3O4/Li2B2O4 nanocomposites as a favorable hydrogen capacitor were investigated to enhance hydrogen storage performance.

Synthesis, characterization, and electrochemical evaluation of SnFe2O4@MWCNTS nanocomposite as a potential hydrogen storage material

“…Discharge capacity of different materials was recorded in Table 2 with various structures [ [36] , [37] , [38] , [39] , [40] , [41] ]. Among the various nanoparticles and nanocomposite, the best efficiency was related to SnFe 2 O 4 @MWCNTs.…”
