The silicone has been received many attentions due to its high capacity for Lithium ion battery (LIB). However, it is necessary to solve some problems such as larger volumetric change than general graphite anode. Although the great mechanical properties of polyurethane (PU) can be a good solution to solve the problem, it is hard to ues because the TPU have low affinity with the inorganic material. Herein, the Si-PU was synthesized using urethane condensation reaction of diol-terminated glycidyl azide polymer (GAP-diol) and, azide-alkyne click reaction of azido-silane. In addition, to enhance physical properties of the synthesized polymer, the crosslinkability was introduced by 2-Hydroxyethyl methacrylate (HEMA). The great mechanical properties of the crosslinked Si-PU can provide stability of capacity, and the conjugated silane can give the high affinity between the polymer and the inorganic material. |
