dc.description.abstractPhase inversion is a simple process to prepare porous thin films for lithium ion battery (LIB) separators. However, controlling porous morphologies during phase inversions for efficient lithium ionic transportation is a critical issue for more optimized battery performances. Here, we report an LIB separator via phase inversion by selecting non-solvents from the combinatorial approach. Interestingly, the formation of PVdF-HFP skeletons was governed by the controlled phase inversion with various mixtures of water, methanol, ethanol and 2-propanol. For a single non-solvent system, a water-based non-solvent (4 wt% water) was the best choice for the phase-inversion-based PVdF-HFP separators for LIBs. However, when a mixture of 2 wt% water and 3 wt% methanol was used as the non-solvent, the best rate capability and long-term stability were obtained, which led to better LIB performances than those of commercialized polyethylene separators.-
