Abstract
The preparation of the size-controlled monomer-capped amorphous and crystalline tin nanoparticles using new capping agents, 2,4,6-tri(2-pyridyl)-1, 3,5-triazine and 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine, was reported. It was observed that TT-capped Sn electrodes of the after cycling showed good adhesion on the current collector while the DT-capped sample was severely separated from the current collector. It was also observed that TT-capped tin nanoparticles reduced the formation of surface cracks induced from the volume change in the LixSny phase. In terms of the irreversible capacity, the monomer-capped Sn was comparable to the commercially used graphite anode materials.
