The voltage profiles of the charging discharging curves exhibit quick capacity fade with cycle number in cu foil and cu 0cnts due to the lithiophobicity and the uneven grain size, while the voltage profiles show highly overlapped for cu 2cnts and cu 5cnts as exhibited in fig. 3 c. capacity retention of cu 2cnts on 240th cycle is 98.2%, which is.

Subsequently, cu cu cnts cu composite copper foil (1) with a sandwich thickness of 8 μm was prepared by combining additives of 3 mercapto 1 propanesulfonate (mps) and cl −. the results show that the resistivity of the composite foil is 1.89 × 10 −8 Ω·m, which increased only 2%. the tensile strength σ is 582 mpa, the elongation ε is 3. Carbon nanotubes (cnts) are considered ideal nanoscale reinforcement for the development of high performance metal matrix composites due to their unique structure and excellent mechanical properties. however, cnts are easy to agglomerate and have poor wettability with the aluminum matrix, resulting in unsatisfactory effects when added to the aluminum melt. in this study, cu coated carbon. Cnt cu composites can be fabricated by two routes, (i) powder based mixing and compaction of cnts and cu 5,6,7,8,9,10,11,12,13 or (ii) cu electrodeposition on into cnt assemblies 1,2,3,4, 14,15,16.
