Flexible Solid-State Lithium-Ion Batteries: Materials and Structures

“…This structure is similar to a sandwich and is the most widely used battery structure. This structure has received a lot of research [123][124][125]. Koo et al [103] developed a UFLIB by using a generic transfer method (Figure 14a).…”

Fabrication of well-aligned Co-MOF arrays through a controlled and moderate process for the development of a flexible tetrabromobisphenol A sensor

“…41 Composites of conductive MOFs with carbon materials can greatly improve electrical performance while maintaining and amplifying other mechanical, thermal, and chemical properties. [42][43][44] In recent years, the combination of MOFs and flexible sensors as electrochemical sensors has attracted great interest.…”

Phosphorus-Doped FeOF Nanoparticle-Based Cathodes for Lithium Storage

“…25−27 Moreover, introducing P into the material can alter the charge balance and endow the material with certain pseudocapacitive properties, thereby improving the rate performance of the material. 28,29 The weak M−P bond enhances the electrochemical activity and reversible redox reaction characteristics of electrode materials, which can improve the rate performance of LIBs. 30 Furthermore, the design of nanostructures not only shortens the electron/ion transport distance but also alleviates the volume expansion of the material, thereby effectively improving the reaction kinetics.…”

“…When using O to partially substitute F in FeF 3 , the ionicity of Fe–F is reduced and the lattice defects are increased, which can integrate the advantages of fluoride and oxide. , However, the rate performance and cycle stability of FeOF are still unsatisfactory because of the low ionic/electronic conductivities, the aggregation of Fe nanoparticles, side reactions of Fe with electrolytes, and the high electronegativity of Fe–F. , Significant efforts have been made to overcome these obstacles, including doping heteroatoms, morphology design, preparation of nanomaterials and composite structures, and so forth. ,, Ion doping has been widely regarded as an effective strategy for enhancing structural stability and improving electronic structure/properties; thus, heteroatom doping may be a straightforward way to improve electrochemical performance. − Especially, non-metal dopants might induce the reconstruction of charge distribution around the sites of the parent material, which may improve the redox activity of the material. − However, the relevant electrochemical mechanism caused by non-metal doping has not been clearly understood. Phosphorus has higher electrical conductivity and the ability to reduce the adsorption energy of Li + to facilitate the interfacial kinetics of Li + intercalation. − Moreover, introducing P into the material can alter the charge balance and endow the material with certain pseudocapacitive properties, thereby improving the rate performance of the material. , The weak M–P bond enhances the electrochemical activity and reversible redox reaction characteristics of electrode materials, which can improve the rate performance of LIBs . Furthermore, the design of nanostructures not only shortens the electron/ion transport distance but also alleviates the volume expansion of the material, thereby effectively improving the reaction kinetics .…”
