Abstract

Almost all implantable electronic medical devices (IEMDs) are powered by bulky Li‐ion batteries (LIBs), limiting their miniaturization and lifespan advancements. In addition, LIBs contain toxic materials and flammable electrolytes that are dangerous if they leak into human organs. In this context, there is an urgent need to explore new approaches and concepts that can address the critical challenges of designing novel electrochemical energy storage systems and gain a mechanistic understanding of the phenomena taking place in diverse scenarios. This review summarizes recent advancements in biocompatible supercapacitors (B‐SCs) as a power source for various IEMDs, offering a potential solution to these challenges. Different types of IEMDs and their power requirements are briefly discussed, along with challenges arising from energy storage systems and their applications in IEMDs. Given the importance of electrode materials in determining the electrochemical performance of B‐SCs in terms of energy and power densities, different electrode materials and their developments are systematically reviewed. Finally, new insights are offered into potential opportunities and future prospects for the rational design of next‐generation B‐SCs. [ABSTRACT FROM AUTHOR]

Abstract

Aqueous sodium (Na+) ion storage systems face challenges due to sluggish adsorption and diffusion of Na+ ions with larger size, hindering their potential for stationary applications. This issue is addressed by evolving the interfacial electronic coupling in atomically thin 2D WO3/WSe2 heterostructure for efficient Na+ ion storage. Density functional theory (DFT) analysis elucidates the superior charge storage capability for the WO3/WSe2 heterostructure facilitated by the charge transfer from the WO3 – WSe2 (002). The charge transfer from the W‐5d and O‐2p orbitals of WO3 to the valence W‐5d and Se‐4p orbitals of the WSe2 (002) surface boosts the electronic conductivity. As a result, the WO3/WSe2 electrode demonstrates exceptional Na+ ion storage, with a specific capacitance of 378.1 F g−1 at 1 A g−1, excellent rate capability, and long‐lasting cycling durability. The full cell comprising WO3/WSe2 as the negative and MnSe/MnSe2 as the positive electrode achieved a peak energy density of 82.1 Wh kg−1 at a power density of 1873.5 W kg−1, along with high rate capability and long‐cycle durability. Insights gained from this study pave the technique for the rational design and optimization of the interfacial electronic features in 2D heterostructures for next‐generation energy storage devices with enhanced performance and stability.

Abstract

Ammonium-ion (NH4+) charge carriers have recently been considered promising for electrochemical energy storage (EES) systems because of their high safety, low molar mass, and small hydrated radius (3.31 Å). However, finding a kinetically balanced anode and cathode combination for high NH4+-ion storage is challenging. Herein, a new approach for developing a heterostructured electrode was developed by constructing extrinsic pseudocapacitive 2D ultrathin MoS2 nanoflakes clamped on 1D Sb2S3 nanorods (MoS2/Sb2S3) as an anode for high-performance ammonium-ion hybrid capacitors (AIHCs) against the intrinsic pseudocapacitive MnO2 cathode. The engineered MoS2/Sb2S3 heterostructured anode facilitated large interlayer galleries owing to the presence of 2D MoS2 for facial NH4+-ion diffusion and provided a rapid electron pathway through 1D Sb2S3, which promoted a high capacitance of 360 F g−1, low resistance, and stable cycling performance. More importantly, the constructed AIHC delivered a superior energy density of 43.75 W h kg−1 at a power density of 600 W kg−1 and excellent cycling durability over 5000 cycles. These results show that a heterostructured extrinsic pseudocapacitive anode can improve the electrochemical parameters of NH4+ EES systems and replace traditional carbon-based anode materials.

Abstract

Improving the energy share of renewable energy technologies is the only solution to reduce greenhouse gas emissions and air pollution. The high‐performing green battery energy storage technologies are critical for storing energy to address the intermittent nature of renewable energy resources. In recent years, aqueous batteries, particularly Zn‐ion batteries (ZIBs), have achieved and shown great potential for stationary energy storage systems owing to their low cost and safer operation. However, the practical applications of the ZIBs have significantly been impeded due to the gap between the breakthroughs achieved in academic research and industrial developments. The present review discusses the ZIB′s advantages, possibilities, and shortcomings for stationary energy storage systems. The Review begins with a brief introduction to the ZIBs and their charge storage mechanisms based on the structural properties of cathode materials. The scientific and technical challenges that obstruct the commercialization of the ZIBs are discussed in detail concerning their impact on accelerating the utilization of the ZIBs for real‐life applications. The final section highlights the outlook on research in this flourishing field. [ABSTRACT FROM AUTHOR]
