Abstract ：
High-efficient data feature extraction is crucial for the lithium ion battery state of health (SOH) evaluation with high accuracy and low cost. In this work, an evaluation model constructed by long short-term memory (LSTM) neural network processes the single-frequency impedance data as the feature data to predict the current health state of the battery. The feature data of electrochemical impedance spectroscopy is determined by the frequency (4.36 Hz) corresponding to the highest peak change in the distribution of relaxation time diagram during the cyclic process. The real and imaginary part values of this single frequency feature point are taken as an input set, and the corresponding SOH is taken as an output set. A battery SOH model based on the LSTM is constructed and the experimental results show that this model can accurately estimate the SOH of the lithium ion battery with the low root mean square error of 3.36% and mean absolute percentage error of 2.68%, indicating that this model displays the decreased computational load, high accuracy and good practicability.

Abstract ：
Electrochromic (EC) fabrics based on conductive polyaniline (PANI) have demonstrated important application potential in the field of active camouflage due to their ability to reversibly switch color between yellow and green, while their practical applications are greatly limited by their poor cycling performance. Here, a modified EC PANI is developed to achieve long-term stable optical modulation through well-designed anion doping, which optimizes the energy levels and also the microstructures. The modified PANI exhibits an improved cycling performance and could achieve a high optical retention rate of 78% even after 6500 cycles and much higher than that of pristine PANI (6.7%). Also, the EC fabric equipped with modified PANI exhibits excellent cycling performance (900 cycles). Furthermore, the EC fabrics are developed into a self-powered environmentally adaptive camouflage system to show real-world applications in active camouflage.

Abstract ：
Rapid kinetics and stable atom configuration of the catalysts are essential and greatly sought after for bifunctional oxygen reactions and energy conversion devices, but remain unsatisfactory. Herein, the Se dual atoms structure consisting of the periodically arranged Se-P-Se configurations within graphitic nitrogen carbon framework (P-Se dual atoms-NC) is constructed by P directionally mediated single atoms deposition strategy. The in situ/ex situ experiments combining the theoretical calculations reveal that both the inter-site distance effect of the adjacent Se atoms in the NC and the Se-P binding effect endow P-Se dual atoms-NC with a stable atom configuration and ultra-durable lifespan, and the locally polarized electronic micro-environment built by P 2p-Se 3d-C 2p orbital hybridization and the electrons transfer significantly promotes H2O-O2 coupling, boosts the adsorption/desorption of O-intermediates and accelerates the electron transport kinetics. Moreover, the adjacent Se atoms with a periodically arranged structure could provide more sites for the absorption and conversion of reactants. Thus, the as-prepared catalyst exhibits the top-level bifunctional activity with an ultra-low potential difference (Delta E) of 0.58 V and delivers the outstandingly low-temperature specific capacity of 796.41 mAh gZn-1 and the ultra-durable lifespan over 1000 h for assembled zinc-air batteries at -40 degrees C.

Abstract ：
Multicolour electrochromic materials have been considered as a promising alternative to achieve dynamic fullcolour tuning towards next-generation electronic display technology. However, the development of electrochromics with wide colour gamut and subtle multicolour tunability still remains challenging due to inflexible energy level structures in intrinsic active materials. Herein, the electrochromic pi-conjugated polymers with rich and subtle colour tunability were designed and developed based on a fine adjustment on the energy level structures. The chromatic transition covers almost full-colour gamut, and each colour scheme has a rich variety of categories stemming from versatile hues, chromas and lightnesses. Moreover, the multicolour pi-conjugated polymers also demonstrate superior overall electrochromic performance, including fast switching (similar to 1.0 s), high colouration efficiency (160.4 cm(2) C- 1@550 nm) and good reversibility (over 90% retention after 10,000 cycles). As a proof of concept, ultrathin and flexible prototype devices are developed by utilizing the multicolour pi-conjugated polymers as electrochromic active layer, exhibiting a wide colour gamut and highly saturated multicolour tunability. The design principles proposed in this work may also be applicable to diverse optoelectronic applications.

Abstract ：
The development of the real-time evaluation for the catalytic hydrogen evolution perfor-mance under a simple and convinient condiction is urgently needed, but still a great challenge. Herein, a platinum modulated WOxon Ag nanowires (Pt-WOx@Ag NWs) is developed as an optical-electrochemical catalyst to realize an in-situ intuitive evaluation for the hydrogen evolution performance, in which the color of as-prepared Pt-WOx@Ag NWs catalyst changes from the transparent to the deep blue with the increase of the applied potential. The real-time H2 evolution with an H2 turnover frequency (from 0 to 2.26 s-1 per site), optical transmittance (from 80.3% to 48.7% at the wavelength of 630 nm) and energy consumption (from 0 to 0.74 W h in 1 h) is established. The charge transfer and mass transport are greatly promoted by the three demensional Ag NWs conductive network and abundant active sites, which are provided by the platinum modulated WO3 on the Ag substrate. Density functional theory (DFT) calculations indicate that the modified WOxshows the preferred adsorption affinity toward H2O (DGH2O,-0.17 eV), which reach a high coloration efficiency and optical modulation range for the electrochromic reaction. The Pt sites on WOxwith a suitable H binding energy (DGH*, 0.38 eV) efficiently promote the H* conversion and H2 release of water splitting. This work propose an intelligent hydrogen evolution indicator by real-time color change to boost the high-quality development of green hydrogen energy.(c) 2022 Hydrogen Energy Publications LLC.

Abstract ：
Electrochromic materials have been widely-applied in military camouflage and intelligent materials, in consideration of the multicolor display and infrared absorption. However, most of them have a narrow width of absorption spectra, and the electrochromic mechanism is still not well understood, especially in materials based on a copolymer structure in visible and infrared bands. Therefore, based on the polaron model, in order to enhance polarizability, we designed an "electronic donors-electronic acceptor" (D-A) type p-conjugated electrochromic polymer, which has an abundant color (wavelengths from 450 nm to 750 nm) with voltage range (from -0.2 V to 1.0 V). Employing first-principle calculations, we investigated the electrochromism of the polymer, which has a strong connection with the introduced new molecular orbital in the polaron (or cation), comparing with those in the neutral molecule. This study addressed the underlying mechanism for the electrochromic phenomenon and the behavior of the cation. It indicated the polaron molecular orbitals provide the photon absorption, whose energies are in the visible range and result in the electrochromic abundant color. In this work, we provide a molecular design for the adjustment of visible and infrared band absorption, which could have broad application in multicolor and infrared electrochromic materials.

Abstract ：
Homogeneous ion transport during Li+ plating/stripping plays a significant role in the stability of Li metal anodes (LMAs) and the electrochemical performance of Li metal batteries (LMBs). Controlled ion transport with uniform Li+ distribution is expected to suppress notorious Li dendrite growth while stabilizing the susceptible solid electrolyte interfacial (SEI) film and optimizing the electrochemical stability. Here, we are committed to rendering a comprehensive study of Li+ transport during the Li plating/stripping process related to the interactions between the Li dendrites and SEI film. Moreover, rational ion modulation strategies based on functional separators, artificial SEI films, solid-state electrolytes and structured anodes are introduced to homogenize Li+ flux and stabilize the lithium metal surface. Finally, the current issues and potential opportunities for ion transport regulation to boost the high energy density of LMBs are described.

Abstract ：
Electrochromic (EC) batteries realize the visualization of the energy level by naked eye and exhibit great potential in various applications including smart windows and wearable electronics. However, limited by the unstable electrolyte and the lack of matching EC electrodes, EC batteries with high working voltage window and energy density still remain a remarkable challenge. Herein, a highly transparent ion-conducting film (ICF) is employed to develop a rechargeable EC battery. The ICF exhibits extremely high optical transparency (over 85% in visible range) and ionic conductivity (sigma = 0.46 mS cm(-1)). In addition, we fabricated a complementary electrochromic battery (ICF-ECB) based on ICF by assembling the spinel Li4Ti5O12 (LTO) as the EC layer and LiMn2O4 (LMO) as a matching counter electrode. Benefiting from the electrochemically stable ICF and battery-type electrochromic materials, the ICF-ECB delivers a high energy storage performance with an operating voltage of 3.0 V and stable discharging platform at 2.5 V. Impressively, the ICF-ECB demonstrates a high areal power/energy density (2.2 W m(-2), 0.14 W h m(-2)) and excellent cycling stability with 61.2% of its initial optical modulation after 200 cycles. Moreover, the resultant ICF-ECB exhibits an obvious and reversible color transition between yellowish-brown (discharge state) and dark blue (charged state), which endows the capacity of sufficient real-time information on the energy level and work status of the device. It is envisioned that the use of ICF to fabricate the multifunctional EC batteries provides new approach to develop intelligent electronic devices.

Abstract ：
Uncontrolled ion transport and susceptible SEI films are the key factors that induce lithium dendrite growth, which hinders the development of lithium metal batteries (LMBs). Herein, a TpPa-2SO(3)H covalent organic framework (COF) nanosheet adhered cellulose nanofibers (CNF) on the polypropylene separator (COF@PP) is successfully designed as a battery separator to respond to the aforementioned issues. The COF@PP displays dual-functional characteristics with the aligned nanochannels and abundant functional groups of COFs, which can simultaneously modulate ion transport and SEI film components to build robust lithium metal anodes. The Li//COF@PP//Li symmetric cell exhibits stable cycling over 800 h with low ion diffusion activation energy and fast lithium ion transport kinetics, which effectively suppresses the dendrite growth and improves the stability of Li+ plating/stripping. Moreover, The LiFePO4//Li cells with COF@PP separator deliver a high discharge capacity of 109.6 mAh g(-1) even at a high current density of 3 C. And it exhibits excellent cycle stability and high capacity retention due to the robust LiF-rich SEI film induced by COFs. This COFs-based dual-functional separator promotes the practical application of lithium metal batteries.
