Abstract
Mass loading is an important parameter to evaluate the application potential of active materials in high-capacity supercapacitors. Synthesizing active materials with high mass loading is a promising strategy to improve high performance energy storage devices. Preparing electrode materials with a porous structure is of significance to overcome the disadvantages brought by high mass loading. In this work, a Mn3O4/NiMoO4@NiCo layered double hydroxide (MO/NMO/NiCo LDH) positive electrode is fabricated on a carbon cloth with a high mass loading of 20.4 mg cm-2. The MO/NMO/NiCo LDH presents as a special three-dimensional porous nanostructure and exhibits a high specific capacitance of 815 F g-1 at 1 A g-1. Impressively, the flexible supercapacitor based on the MO/NMO/NiCo LDH positive electrode and an AC negative electrode delivers a maximum energy density of 22.5 W h kg-1 and a power density of 8730 W kg-1. It also retains 60.84% of the original specific capacitance after bending to 180° 600 times. Moreover, it exhibits 76.92% capacitance retention after 15 000 charge/discharge cycles. These results make MO/NMO/NiCo LDH one of the most attractive candidates of positive electrode materials for high-performance flexible supercapacitors.

Abstract
Co3 O4 with high theoretical capacitance is a promising electrode material for high-end energy applications, yet the unexcited bulk electrochemical activity, low conductivity, and poor kinetics of Co3 O4 lead to unsatisfactory charge storage capacity. For boosting its energy storage capability, rare earth (RE)-doped Co3 O4 nanostructures with abundant oxygen vacancies are constructed by simple, economical, and universal chemical precipitation. By changing different types of RE (RE = La, Yb, Y, Ce, Er, Ho, Nd, Eu) as dopants, the RE-doped Co3 O4 nanostructures can be well transformed from large nanosheets to coiled tiny nanosheets and finally to ultrafine nanoparticles, meanwhile, their specific surface area, pore distribution, the ratio of Co2+ /Co3+ , oxygen vacancy content, crystalline phase, microstrain parameter, and the capacitance performance are regularly affected. Notably, Eu-doped Co3 O4 nanoparticles with good cycle stability show a maximum specific capacitance of 1021.3 F g-1 (90.78 mAh g-1 ) at 2 A g-1 , higher than 388 F g-1 (34.49 mAh g-1 ) of pristine Co3 O4 nanosheets. The assembling asymmetric supercapacitor delivers a high energy density of 48.23 Wh kg-1 at high power density of 1.2 kW kg-1 . These findings denote the significance and great potential of RE-doped Co3 O4 in the development of high-efficiency energy storage.

Abstract
Reasonable design of electrode materials is the key to solving the low energy density of the supercapacitors. Transition metal oxide Co3O4 material is commonly used in the field of supercapacitors, but the poor cycle stability limits its practical application. Herein, we report 0.3Mn-Co3O4 nanostructures grown on nickel foam by a facile one-step hydrothermal approach. The morphology of the samples can be regulated by the introduction of different amounts of Mn ions. The specific capacitance reaches 525.5 C/g at 1 A/g. The performance of 0.3Mn-Co3O4 material is significantly improved due to its excellent stability and conductivity, which makes it a suitable electrode material for supercapacitors. A flexible asymmetric device is also fabricated using the sample as the cathode. The assembled capacitor still possesses a desirable cycle stability after charging and discharging of 10,000 times, and its capacitance retention rate can reach 83.71%.

Abstract
Layered double hydroxide (LDH) has shown great potential for energy storage due to their high theoretical specific capacitance, relatively low cost and eco-friendliness. LDH, however, always works in alkali aqueous electrolyte for supercapacitors, which brings serious environmental pollution. In this work, a reduced graphite oxide/Fe(CN)63-- nickel cobalt aluminum LDH (RGO/Fe(CN)63--LDH) composite has been prepared via ion-exchange reaction using RGO/LDH as precursor. RGO/Fe(CN)63--LDH electrode provides a specific capacitance of 221 F g-1 in a wide potential window of -1 ~ 0.8 V vs. SCE in Na2SO4 aqueous electrolyte, and which is much higher than that of LDH electrode (3.56 F g-1). Owing to the wide potential window of RGO/Fe(CN)63--LDH electrode, a symmetrical solid supercapacitor device (RGO/Fe(CN)63--LDH//RGO/Fe(CN)63--LDH) with a high voltage of 2.0 V can deliver a high specific energy of 25.2 Wh kg-1 at a specific power of 250 W kg-1, and a capacitance retention of 75% after galvanostatic charging/discharging at 5 A g-1 for 5000 times. This work supplies enlightenment for boosting the capacitive performance of LDHs in neutral electrolyte.
