“…The theoretical capacity of silicon (Si) is 4200 mA hg −1 [29], which is higher than the capacity of graphite (372 mA hg −1 ), has considered being an active anode material for the future lithium-ion batteries (LIBs). However, the severe capacity degradation and the high-volume change during the lithiation-delithiation process may lead to lower Coulombic efficiency.…”

After discovering graphene, the two-dimensional materials have gained considerable interest in the electrochemical applications, especially in energy conversion, storage, and bio-sensors. Siloxene, a novel two-dimensional low-buckled structure of Si networks with unique properties, has received the researcher's attention for a wide range of applications. Though the electronic and optical properties of siloxene have been explored in detail previously, there is a lack of electrochemistry studies of siloxene as the result of material degradation, and the investigation is still open-ended to enhance the electrochemical application. Recently, siloxene has been used for supercapacitor, lithium-ion batteries, and dopamine bio-marker detections. This chapter highlights the recent development of siloxene synthesis and its electrochemical properties in energy and sensor applications. The plannar Si structure with Si 6 rings interconnected with different oxygen, hydroxyl functional groups, and large interlayer spacing of siloxene sheets can promote the active sites for enhanced electrochemical performance. This chapter provides the current state-of-the-art in the field and a perspective for future development in the electrochemistry field of siloxene.

The two Dimensional (2D) materials such as MXene and graphene, are most promising materials, as they have attractive properties and attract numerous application areas like sensors, supper capacitors, displays, wearable devices, batteries, and Electromagnetic Interference (EMI) shielding. The proliferation of wireless communication and smart electronic systems urge the world to develop light weight, flexible, cost effective EMI shielding materials. The MXene and graphene mixed with polymers, nanoparticles, carbon nanomaterial, nanowires, and ions are used to create materials with different structural features under different fabrication techniques. The aerogel based hybrid composites of MXene and graphene are critically reviewed and correlate with structure, role of size, thickness, effect of processing technique, and interfacial interaction in shielding efficiency. Further, freeze drying, pyrolysis and hydrothermal treatment is a powerful tool to create excellent EMI shielding aerogels. We present here a review of MXene and graphene with various polymers and nanomaterials and their EMI shielding performances. This will help to develop a more suitable composite for modern electronic systems.

Presently, the negative electrodes of lithium-ion batteries (LIBs) are constituted by carbon-based materials, which exhibit a limited specific capacity 372 mAh g−1 associated with the cycle in the composition between C and LiC6. Therefore, many efforts are currently made towards the technological development of nanostructured graphene materials because of their extraordinary mechanical, electrical, and electrochemical properties. Recent progress on advanced hybrids based on graphene oxide (GO) and reduced graphene oxide (rGO) has demonstrated the synergistic effects between graphene and an electroactive material (silicon, germanium, metal oxides (MOx)) as electrode for electrochemical devices. In this review, attention is focused on advanced materials based on GO and rGO and their composites used as anode materials for lithium-ion batteries.
