Synthesis and Evaluation of PVA-CN Additives for High Temperature Stability of Secondary Battery Electrolyte |
| 초록 |
Recently liquid electrolyte having excellent ion-conductivity and high electrochemical stability has been used for the secondary battery. But it has been reported there was a serious problem in the high temperature stability. In this research, the development of PVA-CN additive which is used in secondary battery electrolyte was carried out with 2 steps; the 1st step was the dissolution of PVA raw materials and the 2nd step was the synthesis of PVA-CN. The thermal property of the prepared additive was quantitatively analyzed using TGA. The significantly improved thermal stability of the electrolyte containing PVA-CN was also confirmed by monitoring swelling behavior at high temperature, i.e. 29% less swelling effect, although they exhibited slightly lower ion conductivity. This finding clearly suggests the possibility of preventing the swelling issue at the high temperature which is the main cause of dangerous accidents from secondary batteries. |
