Abstract ：
The practical applications of solid-state electrolytes in lithium-ion batteries (LIBs) are hindered by their low ionic conductivity and high interfacial resistance. Herein, an ethoxylated trimethylolpropane triacrylate based quasi-solid-state electrolyte (ETPTA-QSSE) with a three-dimensional (3D) network is prepared by a one-step in-situ photopolymerization method. The 3D network is designed to overcome the contradiction between the plasticizer-related ionic conductivity and the thickness-dependent mechanical property of quasi-solid-state electrolytes. The ETPTA-QSSE achieves superb room-temperature ionic conductivity up to 4.55x10(-3) S cm(-1), a high lithium ion transference number of 0.57, along with a wide electrochemical window of 5.3 V (vs. Li+/Li), which outperforms most ever of the reported solid-state electrolytes. Owing to the robust network structure and the cathode-electrolyte integrated electrode design, Li metal symmetrical cells show reduced interface resistance and reinforced electrode/ electrolyte interface stability. When applying the ETPTA-QSSE in LiFePO4 parallel to Li cells, the quasi-solid-state cell demonstrates an enhanced initial discharge capacity (155.5 mAh g(-1) at 0.2 C) accompanied by a high average Coulombic efficiency of greater than 99.3%, offering capacity retention of 92% after 200 cycles. Accordingly, this work sheds light on the strategy of enhancing ionic conductivity and reducing interfacial resistance of quasi-solid-state electrolytes, which is promising for high-voltage LIBs.

Abstract ：
A lithium-sulfur battery, a potential next-generation secondary battery, is affected by poor conductivity of sulfur and the dissolution of intermediate polysulfides. Here we report a lithium-sulfur battery with ultrahigh sulfur loading and excellent cycling stability using porous graphitic carbon (PGC) as a high-conductivity carrier of sulfur and carbon fiber with crisscross conductive framework as an electric attachment site of sulfur. PGC is fabricated through a simple and environmentally friendly synthesis process involving high-temperature graphitization in a N-2 atmosphere followed by an annealing process in air. Due to the presence of porous graphitic structure, with C-O termination groups, PGC endows the lithium-sulfur battery system with excellent cycling performance. The lithium-sulfur battery cathode constructed by PGC with a sulfur loading of 2.5 mg cm(-2) still retains a high specific capacity of 734.4 mA h g(-1) after 200 cycles. Meanwhile, an ultrahigh sulfur loading of 12.8 mg cm(-2) for a CR2025 coin cell is achieved, which is the highest sulfur loading reported in the literature for the coin cell. The ultrahigh sulfur loading cell also shows good electrochemical properties, profiting from the mesopores terminated with C-O groups, high specific surface area of 1129.9 m(2) g(-1) and high-conductivity graphitic structure.

Abstract ：
The practical applications of lithium sulfur batteries have been greatly restricted by the polysulfide shuttle effect and non-conductivity of sulfur. Here, we report a nickel-catalyzed carbonization method to synthesize three-dimensional (3D) nickel@N-doped carbon-nanotube (CNT) foams for lithium-sulfur batteries. The corresponding carbon/sulfur cathode with a high sulfur loading of 3.71 mg cm-2 possesses a high initial capacity of 855.6 mAh g-1 at 135 mA g-1 and good cyclic stability with a low fading rate of 0.153% per cycle for 100 cycles at 270 mA g-1. The growth of carbon thin layers on the nickel nanoparticles results in the encapsulation of the nanoparticles in the CNTs, which makes the carbon forms highly conductive and prevents the metal nanoparticles from being oxidized by polysulfides. The high conductivity is favorable for the electron transfer between polysulfides and carbon electrode. Moreover, the doped nitrogen atoms on the CNTs have strong chemical adsorption ability for polysulfides, accelerating redox reaction of polysulfides on the carbon electrode (i.e., suppressing the shuttle effect). These unique structural characteristics well explain the excellent electrochemical performance of the assembled batteries. It is believed that the fabricated carbon foam is a promising material for high sulfur-loading lithium-sulfur battery. (c) 2022 Published by Elsevier B.V.

Abstract ：
NASICON-type NaTi2(PO4)(3) (NTP) with stable 3D framework exhibits great application prospect as anode materials for aqueous lithium ion battery (ALIB). However, the low electrical conductivity of NTP adversely affects its rate and cycling performance. Surface coating and lattice doping are considered to be effective means to improve the performance of the material. Herein, carbon coated and Fe-F co-doped NTP anode materials were synthesized for ALIBs. It is found that the LiMn2O4 parallel to NTP-Fe-0.1-F-0.1/C full cell delivers a high discharge specific capacity of 112.8, 103.2 and 96.2 mAh g(-1) at 0.5, 5 and 10 C, respectively, in the voltage range of 0.5-1.9 V when Ni foam is used as gasket for the cell assembly. The performances of the cell especially the cycling lifetime at high charge-discharge rates are further improved using electrochemically stable stainless steel as gasket. A high coulombic efficiency of 100% and a low capacity decay of only 0.8% at 5 C and 14.9% at 10 C are achieved even after 2000 cycles of charge-discharge test. This is the most stable NTP-based ALIBs reported in the literature. The outstanding electrochemical property and the long cycling lifetime of the NTP-Fe-0.1-F-0.1/C material is due to the enhanced structural stability and electron/Li+ ion transfer kinetics.

Abstract ：
Here we report a supercapacitor with high energy density and high cycling stability using low-cost and environmentally friendly CoMoO4/bamboo charcoal (BC) hybrid materials as the cathode. The hybrid materials were fabricated via a one-pot solvothermal reaction followed by an annealing process. The optimized CoMoO4/BC hybrid material has a specific surface area of 74.4 m(2) g(-1), being 1.7-fold higher than that of the CoMoO4 precursor. The hybrid electrode shows a high specific capacitance of 422.3 F g(-1) at 0.5 A g(-1) and 304.8 F g(-1) at 50 A g(-1). The as-assembled CoMoO4/BC parallel to activated carbon supercapacitor exhibits a high energy density of 56.7 W h kg(-1) and 18.3 W h kg(-1) at a power density of 785 W kg(-1) and 40 000 W kg(-1), respectively. Furthermore, it also shows excellent long-term cycling stability. Subjected to 40 000 cycles of charge-discharge test at a current density of 50 A g(-1), there is only about 10% capacitance loss (occurring only during the first 5000 cycles). This excellent electrochemical performance is ascribed to the covalent C-Mo and C-O bonds formed between CoMoO4 and BC as well as the porous feature of the hybrid material, which provide highways for electron transfer and ion transportation within the electrodes and at the electrode-electrolyte interface.

Abstract ：
Lithium-sulfur battery has long been considered as the best choice for the next generation secondary battery. However, the intrinsic insulativity of sulfur and the polysulfide shuttle effect have been the key problems that hinder the commercialization of lithium sulfur batteries. Here, using a facile shearing implement assists thermal synthesis process, in which liquid metal gallium and sulfur (mass ratio1:10) are the only reactants, we create a 3D porous sulfur/gallium hybrid materials (S/Ga). Micro/nanometer liquid metal gallium particles embed in the porous sulfur. The S/Ga cathode lithium cell exhibits a high Coulombic efficiencies of 98.7%, and high specific capacities of 1044 mAh g(-1) after 100 cycles at 1.0 mA cm(-2), and good cyclic stability. During first cycle discharge process of the S/Ga cathode, the sulfur reduces to Li2S8 and dissolves in the electrolyte, then the liquid metal Ga has an intimate electrical contact with conductive carbon substrates. Electrons are easily transferred to high conductive liquid metal Ga. Due to the electron abundance on Ga surface, it shows an electrocatalytic effect for the conversion of soluble lithium polysulfides (Li2S4-8) to Li2S2/Li2S, thus improving S utilization and cyclic stability.
