A remarkable 2.6 times improvement in the power factor is achieved in a porous thermoelectric oxide in the presence of a polyelectrolyte.

High lithium-concentration phosphonium ionic liquids electrolytes have shown outstanding properties even overcoming ammonium derivatives in terms of viscosity and transport properties. Consequently, they have been also combined with fluorinated polymers, such as poly(vinylidene fluoride) (PVDF) or poly(ionic liquids), for solid-state batteries with...

Metal–air batteries are an emerging technology with great potential to satisfy the demand for energy in high-consumption applications. However, this technology is still in an early stage, facing significant challenges such as a low cycle life that currently limits its practical use. Poly(3,4-ethylenedioxythiophene) (PEDOT) conducting polymer has al...

Solid polymer electrolytes that combine both a high lithium-ion transference number and mechanical properties at high temperatures are searched for improving the performance of batteries. Here, we show a salt-free all-polymer nanocomposite solid electrolyte for lithium metal batteries that improves the mechanical properties and shows a high lithium...

New material solutions are searched for the manufacturing and safety of current batteries. Herein, an extrusion printable polymer separator for lithium batteries based on single‐ion polymer electrolytes is presented. The polymer electrolytes are based on methacrylic polymeric nanoparticles (NPs) functionalized with a lithium sulfonamide group combi...

Poly(monothiocarbonate)s are an interesting class of sulfur‐containing materials whose application as solid polymer electrolytes was barely studied, certainly due to the elusive production of diversified polymer architectures. Herein, a new liquid CO2‐sourced bis(α‐alkylidene cyclic carbonate) monomer was designed at high yield to allow its one‐ste...

Eutectogels are an emerging family of soft ionic materials alternative to ionic liquid gels and organogels, offering fresh perspectives for designing functional dynamic platforms in water‐free environments. Herein, the first example of mixed ionic and electronic conducting supramolecular eutectogel composites is reported. A fluorescent glutamic aci...

Ion transport in composite electrodes plays a key role in the electrochemical performance of lithium‐metal batteries (LMBs), particularly at high current densities, and hence, some works have suggested the use of ionic conducting polymers as binders. Herein, in order to assess the importance of the type of ion conduction in binders, two poly(ionic...

This chapter outlines the current state of mixed ionic-electronic conducting composite materials, and discusses the latest advances from a didactic point of view. Beginning with the fundamentals, the electronic conducting agent and its nature is described. This section progresses from previously studied inorganic composites to the latest updates in...

The performance of next generation solid-state lithium metal batteries (LMBs) is intimately related to the ionic-electronic interconnection within the cathode material. In batteries containing liquid electrolytes, the soaking of the electrolyte and the addition of carbon provide sufficient ionic and electronic conductivity through the cathode. Howe...

Mixed ionic-electronic conductors, such as poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) are postulated to be the next generation materials in energy storage and electronic devices. Although many studies have aimed to enhance the electronic conductivity and mechanical properties of these materials, there has been little focus...

Allyl cyanide, CH2CHCH2CN, is a volatile organic compound that is emitted by biogenic and anthropogenic sources. Daytime atmospheric degradation of CH2CHCH2CN may be initiated by reaction with OH radicals, Cl atoms and O3. In this work, we report the gas-phase rate coefficients for the reaction of these atmospheric oxidants with CH2CHCH2CN (k1, k2...
