Abstract
Solid polymer electrolytes have shown to be a promising solution to suppressing dendrite growth for safer and higher performance lithium batteries. This article reports the fabrication and characterization of a series of nanostructured polymer electrolyte membranes (PEMs) comprised of poly(ethylene glycol)/bis(trifluoromethane)sulfonimide lithium electrolyte and acrylate-thiol-ene crosslinked resin using a holographic polymerization (HP). Nanoscale long-range order is observed and this unique structure imposes intriguing mechanical and ion-conducting properties of the PEMs. The modulus of the holographically polymerized PEMs can be tuned to vary from 150 to 1300 MPa while room temperature conductivities of approximate to 2 x 10(-5) S cm(-1) and 90 degrees C conductivity of approximate to 5 x 10(-4) S cm(-1) are achieved. The HP nanostructure is also capable of directing ion transport either parallel or perpendicular to the membrane surface; an unprecedented ionic conductivity anisotropy as high as 3 x 10(5) is achieved. It is anticipated that these PEMs may be excellent candidates for lithium battery applications.
