Toward achieving Li-ion batteries with high energy density, SWCNT/Sn composite paper was electrochemically prepared and the addition effect of formaldehyde (HCHO) and polyethylene glycol (PEG) on Sn electrodeposition morphology was studied. PEG improved the wettability of electroplating bath to enable inhomogeneous Sn embeddedness inside SWCNT paper, and HCHO delivered more nuclear growth. The synergetic effect resulted in a composite paper in which Sn particles with several-hundred nanometer order were distributed. Compared with a commercially-available Cu foil (18 mu m-thickness) with 32 mg at 2 cm(2) (phi 16 mm), the weight of the SWCNT paper (5 mg) is one sixth of that of the Cu foil. The dramatic reduction of the component greatly contributes to the increase in energy density of batteries. (c) 2018 Elsevier B.V. All rights reserved.
