Eletrochromic devices are electrochemical systems that can undergo the optical modulation in response to an applied electrical stimulus. In order to investigate the electrochromic (EC) process mechanism and predict the electrochromic behavior, this paper proposes a physical model that employs tungsten trioxide (WO3), nickel oxide (NiO) and LiClO4-propylene carbonate (PC) solution. Within electrochromic films, electrolytes can transport lithium ions and anions through porous layers of electrochromic films. At the interfaces between solution and porous layers, lithium-ion intercalation and deintercalation take place. Considering both ion diffusion and electromigration, ion transport kinetics is described by Nernst-Plank equation. The partial differential equations (PDEs) for potential consist of Poisson equations for electrolytes and Ohm’s law for WO3 and NiO films. Moreover, the ion injection behavior at the interface is governed by Frumkin-Butler-Volmer (FBV) equation and potential conditions of the stern layer. Finally, a modified Beer-Lambert law incorporating porosity is proposed to explain the mechanism of transmittance. Under constant step potential conditions, the state variables of multiphysics field can be tracked, and the dynamic process of the transmittance and electrode current can be accurately predicted. This physical model can be applied for parameter design and precise control of ECDs, based on the optimization of device characteristics.

“…The development of cathode materials with high capacity, high-voltage flatform, and high stability in metal-ion batteries is always a challenge to scientists [ 1 , 2 , 3 , 4 ]. The traditionally used cathode materials (NCM, LFP) in lithium-ion batteries (LIBs) have some limitations, such as the complexity of fabrication, high cost of precursors (Ni, Co), and toxicity of the fabrication or recycling process [ 5 , 6 , 7 , 8 , 9 , 10 ]. The NCM cathode is not ready for use after single-step fabrication and should be combined with carbon derivatives such as carbon nanotubes or graphene.…”

Owing to their high redox potential and availability of numerous diffusion channels in metal–organic frameworks, Prussian blue analogs (PBAs) are attractive for metal ion storage applications. Recently, vanadium ferrocyanides (VFCN) have received a great deal of attention for application in sodium-ion batteries, as they demonstrate a stable capacity with high redox potential of ~3.3 V vs. Na/Na+. Nevertheless, there have been no reports on the application of VFCN in lithium-ion batteries (LIBs). In this work, a facile synthesis of VFCN was performed using a simple solvothermal method under ambient air conditions through the redox reaction of VCl3 with K3[Fe(CN)6]. VFCN exhibited a high redox potential of ~3.7 V vs. Li/Li+ and a reversible capacity of ~50 mAh g–1. The differential capacity plots revealed changes in the electrochemical properties of VFCN after 50 cycles, in which the low spin of Fe ions was partially converted to high spin. Ex situ X-ray diffraction measurements confirmed the unchanged VFCN structure during cycling. This demonstrated the high structural stability of VFCN. The low cost of precursors, simplicity of the process, high stability, and reversibility of VFCN suggest that it can be a candidate for large-scale production of cathode materials for LIBs.

“…Modern devices that harvest sustainable energy from solar light, wind, or tides and convert it to electrical energy for industrial, agricultural, and portable applications have been increasingly attracting research attention [ 1 , 2 ]. Rechargeable batteries are being used for the storage and management of these renewable energies to meet energy demands [ 3 , 4 , 5 , 6 , 7 ]. Lithium-ion batteries (LIBs) are the most common batteries used in mobile devices, energy storage systems, and electronic vehicles [ 8 , 9 , 10 ].…”

“…Li is the lightest metal and possesses high gravimetric energy density and high volumetric energy; therefore, LIBs can easily be integrated into portable devices such as mobile phones, smart watches, and wireless earphones [ 11 , 12 , 13 ]. However, LIBs have limited application in large-scale systems owing to their short lifetime, toxic production, and toxic recycling processes [ 5 , 12 , 14 ]. The use of LIBs also increases the device temperature and even poses the risk of explosion owing to the expansion of electrodes [ 15 ].…”

Sodium-ion batteries (SIBs) are potential replacements for lithium-ion batteries owing to their comparable energy density and the abundance of sodium. However, the low potential and low stability of their cathode materials have prevented their commercialization. Prussian blue analogs are ideal cathode materials for SIBs owing to the numerous diffusion channels in their 3D structure and their high potential vs. Na/Na+. In this study, we fabricated various Fe-V-incorporated hexacyanoferrates, which are Prussian blue analogs, via a one-step synthesis. These compounds changed their colors from blue to green to yellow with increasing amounts of incorporated V ions. The X-ray photoelectron spectroscopy spectrum revealed that V3+ was oxidized to V4+ in the cubic Prussian blue structure, which enhanced the electrochemical stability and increased the voltage platform. The vanadium ferrocyanide Prussian blue (VFPB1) electrode, which contains V4+ and Fe2+ in the Prussian blue structure, showed Na insertion/extraction potential of 3.26/3.65 V vs. Na/Na+. The cycling test revealed a stable capacity of ~70 mAh g–1 at a rate of 50 mA g–1 and a capacity retention of 82.5% after 100 cycles. We believe that this Fe-V-incorporated Prussian green cathode material is a promising candidate for stable and high-voltage cathodes for SIBs.
