The development of next‐generation materials for essential components in lithium‐ion batteries, such as collectors, is crucial owing to considerations of performance, cost, and environmental impact. From this perspective, new‐generation material studies are being carried out to increase the performance of current collectors and reduce environmental damage. In this study, a novel biodegradable Ag nanoparticle‐doped calcium alginate cryogel was produced and used as the current collector for Li‐ion batteries to improve performance, reduce environmental damage, and develop new‐generation batteries. The synthesis of Ag NPs was achieved using an inexpensive and environmentally friendly chemical reduction method, followed by their incorporation into the gels. Freeze‐drying was employed to obtain cryogels without the inclusions on the current collector. Structural analysis of both the particles and gels was performed via XRD, SEM, EDS, and FTIR, DSC respectively. The results showed that the synthesized Ag NPs were spherical with an average diameter of 10 nm. The cryogels exhibited desirable chemical structures, as indicated by FTIR analysis. The addition of Ag NPs led to changes in peak positions and intensities, indicating crosslinking homogenization and increased hydrophobicity. Galvanostatic Charge/Discharge Analysis was conducted to evaluate the electrochemical performance of the cryogels as current collectors. The cryogels demonstrated balanced lithiation/delithiation behavior but had a limited operational duration, likely due to structural instability. Postmortem analysis conducted by FTIR and DSC analysis for disassembled cryogels showed the presence of lithium salts from the electrolyte in the structure, and the usage of a solid electrolyte was recommended to improve the system's performance.

In this paper, the facile synthesis and characterization aspects of PEDOT:PSS has been presented, in the context of energy storage device technology. PEDOT/PSS particles were synthesized via chemical oxidative polymerization to improve the electrical conductivity. The mechanism for this conductivity enhancement was studied through various chemical and physical characterizations. The structural characterization establishes that all the samples have high surface area and are highly crystalline, showing 3-4 nm spherical nanoparticles with the smoother surface. The electrical conductivity of measured thin film reached 6.23 Â 10 À6 ℧ cm À1 . The use of the PEDOT:PSS as a binders will surely be helpful for scaling up the energy storage technology like high electrical conductivity, the ability for aqueous processing, electrochemical performance, good electrochemical stability and shows good binding ability. It also helps to protect the energy storage devices against electrode particle cracking, solid electrolyte interface (SEI), dendrite formation or lithium plating.

The development of next generation energy storage devices with low self‐discharge rate, high energy density and low cost are the requirements to meet the future and environmental needs. In recent years, energy demand has risen in tandem with population growth and technological advancement. Energy resources are finite. Thus, solving economic difficulties and ensuring their continuous and efficient consumption will require new research and technologies. The use of nanomaterials in energy storage devices improves the performance of the devices with its morphologies and properties like high surface area, tunable pore size, good ionic and conductive properties. It also plays a critical role by improving the long lifespan, safety, and cyclicity of electrodes materials. This short review brings out the main approaches about the comprehensive analysis of the recent advances and future prospect of nanomaterials for energy storage technology and its applications. It discusses the classification of nanomaterials i. e., carbon‐based materials, metal‐oxides, nanowires, conductive polymers, etc. and the environmental impact in the energy storage technologies of nanomaterials. They also make it possible to occupy all the intercalation sites in the particle volume, which results in quick ion diffusion and high specific capacities. Because of these characteristics, electrodes made of nanomaterials can withstand high currents, making them a potential option for storing energy at high power and energy density. The related market study predicts that the worldwide market for nanotechnology in the energy sector will expand from an estimated $ 139.7 million in 2020 to $ 384.8 million in 2030, representing a CAGR (compound annual growth rate) of 10.7 percent from 2021 to 2030. Research indicates that energy storage and conversion systems using nanomaterials are more efficient. Carbon‐based materials, metal‐oxides, nanowires, conductive polymers, etc. added to phase change materials were studied for their high charge and discharge rates. Prior research indicated that several material properties, including size, concentration, form, and phase transition, significantly impacted the storage efficiency of composites. This review article also summarises and discusses the current state of knowledge regarding effective nanomaterials for its role in energy storage and conversion. Finally, possible uses for nanomaterials in new energy storage technologies, including wearable and flexible electronics, grid‐scale energy storage, and electrochemical energy conversion with different applications is discussed.
