Title: Confined versus Unconfined Crystallization in Block Copolymer/Salt Mixtures Studied by Depolarized Light Scattering

Abstract

In this work, crystallization in an ordered lamellar diblock copolymer/salt mixture, polystyrene-block-poly(ethylene oxide) mixed with lithium bis(trifluoromethanesulfonyl)imide salt (SEO/LiTFSI), has been studied using a combination of small-angle X-ray scattering (SAXS), transmission electron microscopy (TEM), and depolarized light scattering (DPLS). Such materials have applications as electrolyte membranes in solid-state lithium batteries. The grain structure of the electrolyte was controlled by manipulating thermal history. Poly(ethylene oxide) (PEO) crystallization was confined within the microphase-separated morphology and did not affect the grain structure in the case of shallow quenches. Deep quenches resulted in unconfined crystallization, where crystal formation does not affect the microphase-separated morphology but does alter the grain structure. The difference between the two modes of crystallization can only be detected by DPLS. This knowledge is particularly relevant for nanostructured electrolytes wherein ion transport is a strong function of grain structure.

Structure and Ionic Conductivity of Polystyrene-block-poly(ethylene oxide) Electrolytes in the High Salt Concentration Limit

Journal Article Chintapalli, Mahati ; Le, Thao N. P. ; Venkatesan, Naveen R. ; ... - Macromolecules

We explore the relationship between the morphology and ionic conductivity of block copolymer electrolytes over a wide range of salt concentrations for the system polystyrene-block-poly(ethylene oxide) (PS-b-PEO, SEO) mixed with lithium bis-(trifluoromethanesulfonyl)imide salt (LiTFSI). Two SEO polymers were studied, SEO(16-16) and SEO(4.9-5.5), over the salt concentration range r = 0.03-0.55. The numbers x and y in SEO(x-y) are the molecular weights of the blocks in kg mol^-1, and the r value is the molar ratio of salt to ethylene oxide moieties. Small-angle X-ray scattering was used to characterize morphology and grain size at 120 °C, differential scanning calorimetry was usedmore »« less

Correlations between Salt-Induced Crystallization, Morphology, Segmental Dynamics, and Conductivity in Amorphous Block Copolymer Electrolytes

Journal Article Thelen, Jacob L. ; Wang, Andrew A. ; Chen, X. Chelsea ; ... - Macromolecules

Block copolymer electrolytes have been shown to increase the cycle life of rechargeable batteries that utilize high capacity lithium anodes. Most block copolymer electrolyte studies have been centered on polystyrene-b-poly(ethylene oxide) (SEO) mixed with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt and are limited to salt concentrations in the vicinity of r[Li]/[EO] = 0.1, where [Li] and [EO] are the concentration of lithium and ethylene oxide moieties, respectively, as the conductivity of poly(ethylene oxide) (PEO) homopolymer electrolytes is maximized at this concentration.Here, in this paper, we study the morphology and conductivity of electrolytes derived from a high molecular weight SEO block copolymer overmore »« less

Intrinsic Ion Transport Properties of Block Copolymer Electrolytes

Journal Article Sharon, Daniel ; Bennington, Peter ; Dolejsi, Moshe ; ... - ACS Nano

Knowledge of intrinsic properties is of central importance for materials design and assessing suitability for specific applications. Self-assembling block copolymer electrolytes (BCEs) are of great interest for applications in solid-state energy storage devices. A fundamental understanding of ion transport properties, however, is hindered by the difficulty in deconvoluting extrinsic factors, such as defects, from intrinsic factors, such as the presence of interfaces between the domains. Here, we quantify the intrinsic ion transport properties of a model BCE system consisting of poly(styrene-block-ethylene oxide) (SEO) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt using a generalizable strategy of depositing thin films on interdigitated electrodes andmore »« less

Molecular Level Differences in Ionic Solvation and Transport Behavior in Ethylene Oxide-Based Homopolymer and Block Copolymer Electrolytes

Journal Article Sharon, Daniel ; Bennington, Peter ; Webb, Michael A. ; ... - Journal of the American Chemical Society

Block copolymer electrolytes (BCE) such as polystyrene-block-poly(ethylene oxide) (SEO) blended with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) and composed of mechanically robust insulating and rubbery conducting nanodomains are promising solid-state electrolytes for Li batteries. Here, we compare ionic solvation, association, distribution, and conductivity in SEO-LiTFSI BCEs and their homopolymer PEO-LiTFSI analogs toward a fundamental understanding of the maximum in conductivity and transport mechanisms as a function of salt concentration. Ionic conductivity measurements reveal that SEO-LiTFSI and PEO-LiTFSI exhibit similar behaviors up to a Li/EO ratio of 1/12, where roughly half of the available solvation sites in the system are filled, and conductivity ismore »« less

Structure–Conductivity Relationships in Ordered and Disordered Salt-Doped Diblock Copolymer/Homopolymer Blends

Journal Article Irwin, Matthew T. ; Hickey, Robert J. ; Xie, Shuyi ; ... - Macromolecules

We examine the relationship between structure and ionic conductivity in salt-containing ternary polymer blends that exhibit various microstructured morphologies, including lamellae, a hexagonal phase, and a bicontinuous microemulsion, as well as the disordered phase. These blends consist of polystyrene (PS, M_n ≈ 600 g/mol) and poly(ethylene oxide) (PEO, M_n ≈ 400 g/mol) homopolymers, a nearly symmetric PS–PEO block copolymer (M_n ≈ 4700 g/mol), and lithium bis(trifluoromethane)sulfonamide (LiTFSI). These pseudoternary blends exhibit phase behavior that parallels that of well-studied ternary polymer blends consisting of A and B homopolymers compatibilized by an AB diblock copolymer. The utility of this framework is thatmore »« less
