Nanoporous and thermally stable polymer separator for high-speed rechargeable lithium ion battery |
| 초록 |
We reported that the straight nanopores in cellulose acetate (CA) polymers for battery gel separators could be generated by utilizing both Ni(NO3)2·6H2O and water pressure. When polymer film was exposed to water pressure, the continuous nanopores were generated after complexing with Ni(NO3)2·6H2O. These results could be explained by that polymer chains were weakened because of the plasticization effect of the Ni(NO3)2·6H2O incorporated into the CA. The well controlled CA membrane after water pressure treatment enabled fabrication of highly reliable cell by utilizing 2032-type coin cell structure. The resulting cell performance exhibited both the effect of the physical morphology of CA separator and the chemical interaction of electrolyte with CA polymer which facilitates the Li-ion in the cell. |
