内容記述 | An aliphatic hyper-branched polycarbonate (HBPC) was synthesized as a novel host material for solid polymer electrolytes (SPEs). The HBPC was synthesized through A2 + B3 polymerization to yield a branched polycarbonate structure. HBPC-based SPE films were prepared by drying mixed solutions of HBPC and 1?60?mol% LiClO4. The temperatures for 5% weight loss (Td5s) of the HBPC-based SPEs were in the range of 174.4?189.3?°C, higher than those in normal use. The HBPC-based SPE exhibited higher ionic conductivities (1.86?×?10?4?S?cm?1 at 70?°C and 8.52?×?10?6?S?cm?1 at 30?°C) than a poly(trimethylene carbonate) (LPC)-based SPE (4.79?×?10?6?S?cm?1 at 70?°C and 8.32?×?10?8?S?cm?1 at 30?°C) for 20?mol% lithium content. Activation energies of lithium ion transport for the HBPC- and LPC-based SPEs were estimated to be 11.47 and 15.88?kJ?mol?1, respectively. Introduction of this branched structure in polycarbonates is effective for promoting lithium ion transport. | |||||
