Metal Halide Perovskites for Energy Storage Applications

Abstract

The increasing global energy demand requires the coordinated development of energy conversion and energy storage materials. Metal halide perovskites have emerged as strong semiconductor candidates for both applications. While metal halide perovskites have received much attention for a range of energy conversion devices, there is a limited use of these materials in energy storage devices. This review summarizes the current status of metal halide perovskites for Li-ion battery and supercapacitor applications while mainly focusing on the device architecture, synthesis method, and material properties. Special attention is placed on the impact of the morphology, defect density and doping of the perovskite active layer on the performance of these devices. Finally, perspectives for the further development of this field are proposed.

Quantifying Capacitive and Diffusion-Controlled Charge Storage from 3D Bulk to 2D Layered Halide Perovskite-Based Porous Electrodes for Efficient Supercapacitor Applications

“…Hybrid halide perovskites (HHPs) are the materials of the decade as tremendous progress in perovskite solar cells, − perovskite light-emitting diodes, − perovskite-based detectors, and memristor applications has been observed owing to their superior optoelectronic properties such as high carrier mobility, , high absorption coefficient, , ambipolar charge transport, , high quantum yield, , high color purity, excellent defect tolerance with low-temperature solution −processing, and tunable emission over a broad spectrum . Due to the mixed electronic–ionic conductivity, hybrid perovskites have also attracted attention toward energy storage applications. − Ions in the perovskite materials (anions and cations) have much lower activation energies and modest ionic diffusion coefficients to move within the perovskite active layer when subjected to an external electric field or under light illumination. − This feature of HHPs is a merit for energy storage applications including many switchable photovoltaic and nonvolatile memory applications. , HHPs have been used in lithium-ion batteries (LIBs), photorechargeable batteries (PRBs), and supercapacitors. ,, Ahmad et al have demonstrated two-dimensional (2D) perovskite-based efficient PRBs having capacities of up to 100 mAh g –1 . However, the typical drawbacks of LIBs and PRBs are a slow charging response time and a low power density, while capacitors have much lower energy density compared to batteries.…”

Hybrid Halide Perovskite‐Based Electrochemical Supercapacitors: Recent Progress and Perspective

“…Recently, MHP materials have also received much attention in energy storage applications due to their mixed electronic−ionic properties. [ 18,19 ] In this direction, MHP materials are used in lithium‐ion batteries (LIBs), photorechargeable batteries (PRBs), and ESCs. [ 20–22 ] Typical stumbling blocks of rechargeable batteries are slow charging rate and low power density, while capacitors have low energy density than batteries.…”

“…The area capacitance of thin-film-based devices is in the range of μF cm À2 , as also reported in the literature. [18,19] Perovskite powder prepared from single crystals has large microstrain, which increases the overall ion migration with the increased surface area than that of thin-film devices. In general, changes in crystallite size and microstrain are due to lattice defects introduced during the synthesis and crystal growth stages of energetic particles.…”

Effect of 1,3-Disubstituted Urea Derivatives as Additives on the Efficiency and Stability of Perovskite Solar Cells

“…Metal halide perovskites (MHPs), owing to their outstanding optoelectronic properties, have emerged as an attractive class of semiconductors for single-junction and tandem solar cells, , light emitting diodes (LEDs), , photodetectors, X-ray imaging scintillators and energy storage . Particular achievement has been made in the field of perovskite solar cells (PSCs), which achieved exceptional power conversion efficiency (PCE) exceeding 25% in only a few years, approaching that of the established inorganic thin-film devices based on crystalline silicon or copper indium gallium selenide. − Despite the rapid progress in the PCE of PSCs, their long-term and operational stability are still the main concerns for their practical and commercial applications. , Among the layers in the device structure, the optimization of perovskite film quality plays an essential role in overcoming the stability issues in PSCs .…”
