Abstract
It remains a great challenge to design and manufacture battery-type supercapacitors with satisfactory flexibility, appropriate mechanical property, and high energy density under high power density. Herein, a concept of porous engineering is proposed to simply prepare two-layered bimetallic heterojunction with porous structures. This concept is successfully applied in fabrication of flexible electrode based on CuO-Co(OH)2 lamella on Cu-plated carbon cloth (named as CPCC@CuO@Co(OH)2 ). The unique structure brings the electrode a high specific capacity of 3620 mF cm-2 at 2 mA cm-2 and appropriate mechanical properties with Young's modulus of 302.0 MPa. Density functional theory calculations show that porous heterojunction provides a higher intensity of electron state density near the Fermi level (E-Ef = 0 eV), leading to a highly conductive CPCC@CuO@Co(OH)2 electrode with both efficient charge transport and rapid ion diffusion. Notably, the supercapacitor assembled from CPCC@CuO@Co(OH)2 //CC@AC shows high energy density of 127.7 W h kg-1 at 750.0 W kg-1 , remarkable cycling performance (95.53% capacity maintaining after 10 000 cycles), and desired mechanical flexibility. The methodology and results in this work will accelerate the transformative developments of flexible energy storage devices in practical applications.

Abstract
Supercapacitors (SCs) can effectively alleviate problems such as energy shortage and serious greenhouse effect. The properties of electrode materials directly affect the performance of SCs. Rare earth (RE) is known as "modern industrial vitamins", and their functional materials have been listed as key strategic materials. In the past few years, the number of scientific reports on RE-based nanomaterials for SCs has increased rapidly, confirming that adding RE elements or compounds to the host electrode materials with various nanostructured morphologies can greatly enhance their electrochemical performance. Although RE-based nanomaterials have made rapid progress in SCs, there are very few works providing a comprehensive survey of this field. In view of this, a comprehensive overview of RE-based nanomaterials for SCs is provided here, including the preparation methods, nanostructure engineering, compounds, and composites, along with their capacitance performances. The structure-activity relationships are discussed and highlighted. Meanwhile, the future challenges and perspectives are also pointed out. This Review can not only provide guidance for the further development of SCs but also arouse great interest in RE-based nanomaterials in other research fields such as electrocatalysis, photovoltaic cells, and lithium batteries.

Abstract
The development of poly(3,4-ethylenedioxythiophene) (PEDOT) with high specific capacitance is the key to pursuing high-performance supercapacitors, and the electrochemical properties of PEDOT are closely related to the oxidation degree and conjugated chain length of its molecular chain. In this work, the influences of various oxidants (FeCl3, Fe(Tos)3 and MoCl5) on the molecular chain structure and capacitive properties of PEDOT via vapor phase polymerization were systematically investigated. Fe(Tos)3 can significantly improve the degree of oxidation and the length of the conjugated chain of PEDOT compared to FeCl3 and MoCl5, enhancing the conductivity and providing more active sites for Faraday reaction. Therefore, the PEDOT/P(Fe(Tos)3) electrode displays a considerable conductivity of 73 S cm-1, high areal capacitance (419 mF cm-2) and excellent electrochemical stability under the different bent state. Moreover, the conjugated structure strengthens the interaction between PEDOT chains, achieving good cycle stability. Therefore, Fe(Tos)3 is an ideal oxidant for obtaining high-performance PEDOT electrode materials.

Abstract
A facile "carbon quantum dots glue" strategy for the fabrication of honeycomb-like carbon quantum dots/nickel sulphide network arrays on Ni foam surface is successfully demonstrated. This design realizes the immobilization of nanosheet arrays and maintains a strong adhesion to the collector, forming a three-dimensional (3D) honeycomb-like architecture. Thanks to the unique structural advantages, the resulting bind-free electrode with high active mass loading of 6.16 mg cm-2 still exhibits a superior specific capacitance of 1130F g-1 at 2 A g-1, and maintains 80% of the initial capacitance even at 10 A g-1 after 3000 cycles. Furthermore, the assembled asymmetrical supercapacitor delivers an energy density of 18.8 Wh kg-1 at a power density of 134 W kg-1, and outstanding cycling stability (100% of initial capacitance retention after 5000 cycles at 5 mA cm-2). These impressive results indicate a new perspective to design various binder-free electrodes for electrochemical energy storage devices.

Abstract
The development of battery systems with high specific capacity and power density could fuel various energy-related applications from personal electronics to grid storage. (Fe2.5Ti0.5)1.04O4 possessing high theoretical specific capacity has been considered as a promising high rate anode material for lithium ion batteries due to the replacement of Fe3+ (0.64 Å) by Ti4+ (0.68 Å) with a larger radius to expand the interlayer space for ion intercalation. However, its extreme volume variation upon cycling as well as poor electrical conductivity hinder its further application. To tackle the above problems, in this work, we successfully synthesized two-dimensional (2D) (Fe2.5Ti0.5)1.04O4/C/MXene architecture derived from Ti3C2Tx MXene via solvo-hydrothermal, ultrasound hybridizing and high temperature annealing processes. The (Fe2.5Ti0.5)1.04O4/C/MXene shows a high discharge capacity of 757.2 mAh g-1 after 800 cycles at a current density of 3 A g-1 with excellent rate performance. The superior electrochemical performances are triggered primarily by the incorporation of carbon and MXene into (Fe2.5Ti0.5)1.04O4 moiety to construct a 2D layered structure, which can improve the ion diffusion and electron transport. In addition, the synergistic contributions from diffusion controlled and capacitive processes for (Fe2.5Ti0.5)1.04O4/C/MXene improve the ion diffusion rate and offer high specific capacity at high current density. The MXene-derived synthesis strategy in this work should be a promising pathway to synthesize other anode materials with 2D layered architecture for high performance lithium storage.

Abstract
Layered metal hydroxide salts (LHSs) have recently gained extensive interests as an efficient electrode material for supercapacitors (SCs). Herein, we report, for the first time ever, the synthesis of a cobalt-nickel layered hybrid organic-inorganic LHS that was intercalated with benzoate anions (B-CoNi-LHSs) and observe a high performance as electrode materials for hybrid supercapacitors (HSCs). B-CoNi-LHSs were synthesized by using a co-precipitation method, where sodium benzoate was added dropwise to cobalt and nickel salt solution, without the addition of any organic solvent or surfactant. Due to the intercalation of anions and synergistic interactions of the multi-metallic components, the B-CoNi-LHSs electrode showed a high specific capacity of 570 C g-1 (specific capacitance of 1267 F·g-1) at 1 A g-1, excellent rate performance (65% from 1 to 10 A g-1) and outstanding cycling performance (81.09% over 8000 cycles), in comparison to the mono-metallic counterparts. An HSC device, assembled by using B-CoNi-LHSs as the positive electrode and activated carbon (AC) as the negative one, exhibited a power density of 780 W kg-1 at the energy density of 31.7 Wh kg-1, and 8543 W kg-1 at 18.1 Wh kg-1. Results from this study show that the organic-inorganic hybrids of layered dual-metal hydroxides intercalated with benzoate anions may be a viable candidate as electrode materials for high-performance SCs.

Abstract
Considering the importance of conductive polymer nanocomposite, the present paper attempts to create a method for increasing the conductivity of poly(o-aminophenol). Nanocomposite MnO2/poly(o-aminophenol) thin film was synthesized by using pulse potential electrodeposition technique on a graphite electrode. In this research, nanoparticles of MnO2 are used after synthesis to prepare polymer nanocomposites in one-step. Appending of MnO2 to polymer matrix increases the current. This current growth could be ascribed to the synergistic MnO2 nanostructure, which presents the superior surface area and smaller particle size that is increasingly acting sites. Morphology or samples composition was investigated by the scanning electron microscope and the UV-Vis method, which clearly indicate the formation of nanocomposites. The findings show that the capacitive behavior of MnO2-poly(o-aminophenol) is superior to poly(o-aminophenol), especially at high potential high temperatures. The results showed that MnO2/poly(o-aminophenol) had a higher level of activity and the electron transfer capability was faster than pure polymer film. The doped MnO2 polymer also has excellent cyclic performance and load discharge features. Additional electrochemical properties of these polymer composites were observed against pure polymer so that capacity of 645 Fg−1 has been designated.
