From the standpoint of material diversification and sustainability, the development of so-called “beyond lithium-ion” battery chemistries is important for the future of energy storage. Na, K, and Ca are promising as the basis for battery chemistries in that these elements are highly abundant. Here, a series of single-ion conducting polymer electrolytes (SIPEs) for Na, K, and Ca batteries are synthesized and investigated. The two classes of metal cation neutralized SIPEs compared are crosslinked poly(ethylene glycol) dimethacrylate-x-styrene sulfonate (PEGDMA-SS) and poly(tetrahydrofuran) diacrylate-x-4-styrenesulfonyl (trifluoromethylsulfonyl)imide (PTHFDA-STFSI); three cation types, three charge densities, and four swelling states are examined. The impact on conductivity of all of these parameters is studied, and in conjunction with small angle X-ray scattering (SAXS), it is found that promoting ion dissociation and preventing the formation of dense ionic aggregates facilitates ion transport. These results indicate many of the lessons learned from the Li SIPE literature can be translated to beyond Li chemistries. At 25 °C, the best performing Na/K and Ca exchanged polymers yield active cation conductivity on the order of 10−4 S/cm and 10−6 S/cm, respectively, for ethylene carbonate:propylene carbonate gelled SIPEs, and 10−5 S/cm and 10−7 S/cm, respectively, for glyme gelled SIPEs.

High-aspect-ratio cobalt-oxide-coated Tobacco mosaic virus (TMV-) assembled polytetrafluoroethylene (PTFE) nonstick surfaces were integrated with a solvent-free polymer electrolyte to create an anode-electrolyte interface for use in lithium-ion batteries. The virus-assembled PTFE surfaces consisted primarily of cobalt oxide and were readily intercalated with a low-molecular-weight poly (ethylene oxide) (PEO) based diblock copolymer electrolyte to produce a solid anode-electrolyte system. The resulting polymer-coated virus-based system was then peeled from the PTFE backing to produce a flexible electrode-electrolyte component. Electrochemical studies indicated the virus-structured metal-oxide PEO-based interface was stable and displayed robust charge transfer kinetics. Combined, these studies demonstrate the development of a novel solid-state electrode architecture with a unique peelable and flexible processing attribute.

A new Mg2+-ion conducting polymer electrolyte based on Poly (ethylene glycol) complexed with Mg(CH3COO)2has been prepared using solution-cast technique. DSC, Composition-dependent conductivity at different temperatures, dielectric studies, and transference number measurements have been performed to characterize the polymer electrolytes. The DSC measurements show decrease in melting point with increase in salt concentration. Out of five different compositions studied, the 85PEG: 15Mg(CH3COO)2polymer-salt complex showed the highest conductivity with σ = 1.07 x 10-6 S/cm at room temperature (30°C). The transport number measurements have shown that the electrolyte is an ionic conductor. Using the electrolyte, an electrochemical cell with the configuration Mg/(PEG+Mg(CH3COO)2)/(I2+C+electrolyte) has been fabricated and its discharge characteristics studied.

In this work, we report the development of “one piece” electrochemical actuator fibers, presenting linear deformations, and working in open-air. The hollow fiber shaped actuators are synthesized as three components Interpenetrating Polymer Network (IPN). The electronic conducting polymer (ECP), poly(3,4-ethylenedioxythiophene) (PEDOT), is embedded in a hollow fiber shape matrix working as two ECP concentric electrodes. The host matrix which presents an IPN type architecture is composed of two poly(ethylene oxide) networks, crosslinked in the presence of each other. Strains up to 3 % and forces between 50 and 300 mN are realized in a two electrodes configuration, in open-air.
