“…Li-ion doped plastic crystalline matrices are stable over a potential of 5 V and very attractive for battery applications in combination of possible structural vibrations of plastic crystal matrices and conductivities. 410 Zhang et al 411 prepared a novel solid-state composite polymer electrolyte based on PEO by using LiClO 4 as doping salts and inorganic hybrid poly(cyclotriphosphazene-co-4, 40-sulfonyldiphenol) (PZS) microspheres as filters due to the fact that this electrolyte leads to higher enhancement in ionic conductivity compared to traditional ceramic fillers such as SiO 2 . Other promising candidates for solid state electrolytes are inorganic materials (brittle superionic glass electrolytes).…”

There is an increasing worldwide demand for high energy density batteries. In recent years, rechargeable Li-ion batteries have become important power sources, and their performance gains are driving the adoption of electrical vehicles (EV) as viable alternatives to combustion engines. The exploration of new Li-ion battery materials is an important focus of materials scientists and computational physicists and chemists throughout the world. The practical applications of Li-ion batteries and emerging alternatives may not be limited to portable electronic devices and circumventing hurdles that include range anxiety and safety among others, to their widespread adoption in EV applications in the future requires new electrode materials and a fuller understanding of how the materials and the electrolyte chemistries behave. Since this field is advancing rapidly and attracting an increasing number of researchers, it is crucial to summarise the current progress and the key scientific challenges related to Li-ion batteries from theoretical point of view. Computational prediction of ideal compounds is the focus of several large consortia, and a leading methodology in designing materials and electrolytes optimized for function, including those for Li-ion batteries. In this Perspective, we review the key aspects of Li-ion batteries from theoretical perspectives: the working principles of Li-ion batteries, the cathodes, anodes, and electrolyte solutions that are the current state of the art, and future research directions for advanced Li-ion batteries based on computational materials and electrolyte design.

“…But the dispersion of organo‐modified MMT mostly increases the σ dc values of the PEO–LiClO 4 electrolytes and also the PMMA–LiClO 4 electrolytes by about 2 order of magnitude. At low salt concentrations, the σ dc values of PEO–LiClO 4 and PMMA–LiClO 4 electrolytes are found of the order of ∼10 −9 to 10 −7 , at room temperature, which may increase by two to three orders of magnitude with the addition of inorganic nanofillers and the liquid plasticizers . Figure shows that the σ dc values of the (PMMA–PEO)–LiClO 4 electrolyte films of fixed salt concentration and without MMT vary by two orders of magnitude (∼10 −7 −10 −9 S cm −1 ) with the sample preparation methods.…”

“…different methods of preparation (solution–cast, melt compounding, ultrasonic assisted, microwave irradiated, ion irradiated methods, etc. ), addition of liquid plasticizers, dispersion of inorganic nanofillers, use of different salts, and their blending with other polymers . These studies revealed that the addition of plasticizers always increased the degree of salt dissociation and the amorphous phase of the SPE materials, which resulted in the increase of their ionic conductivity.…”

The solid polymeric nanocomposite electrolyte (SPNE) films based on the blend of amorphous poly(methyl methacrylate) (PMMA) and semicrystalline poly(ethylene oxide) (PEO) (PMMA:PEO 5 80:20 wt %) doped with lithium perchlorate (LiClO 4 ) salt and montmorillonite (MMT) clay nanofiller were prepared by classical solution cast, ultrasonic assisted solution cast and ultrasonication along with microwave irradiated solution cast followed by melt-pressing methods. The X-ray diffraction study of these electrolytes revealed the amorphous behavior with intercalated MMT structures. The suppressed crystallinity of PEO in the blend electrolyte complexes confirmed the existence of single discrete PEO chains confined within the PMMA domains. The dielectric relaxation spectroscopy of these materials was performed over the frequency range 20 Hz to 1 MHz, at ambient temperature. The presence of a singular relaxation peak in the loss tangent and electric modulus spectra of these electrolytes confirms a coupled cooperative chain segmental dynamics of the blend polymer owing to their miscible amorphous morphology. The behavior of transient complexes formed between the polymers functional groups, lithium cations and the intercalated MMT nanoplatelets was explored. The ambient temperature ionic conductivity of these electrolytes depends on the structural dynamics and the sample preparation methods. It is revealed that the presence of PEO in the PMMA matrix mainly governs the structural, dielectric, and ionic properties of these SPNE films.
