Lithium-sulfur batteries can potentially be used as a chemical power source because of their high energy density. However, the sulfur cathode has several shortcomings, including fast capacity attenuation, poor electrochemical activity, and low Coulombic efficiency. Herein, multi-walled carbon nanotubes (CNTs), graphene oxide (GO), manganese dioxide are introduced to cathode. A MnO2/GO/CNTs-S composite with unique three-dimensional (3D) architecture was synthesized by one-pot method heat...
Transition-metal sulfides are key cathode materials for thermal batteries used in military applications. However, it is still a big challenge to prepare with good electronic conductivity and stability. Herein, we rapidly synthesized Co-doped NiS2 micro/nanostructure using hydrothermal method. We found that the specific capacity of Ni1–xCoxS2 increases amount Co doping. Under current density 100 mA cm–2, Ni0.5Co0.5S2 was about 1565.2 As g–1 (434.8 mAh g–1) cutoff voltage 1.5 V. Owing small...
Solid polymer electrolytes (SPEs) are promising substitutes for current flammable liquid to achieve high-safety and high-energy-density lithium metal batteries. Polyethylene oxide (PEO) based solid have attracted increasing attention because of their excellent flexibility, manufacturability, light weight, low-cost processing, while they often suffer from low ionic conductivity at room temperature, transference number unsatisfactory interfacial resistance, which largely restrain practical...
To solve the barriers of poor rate capability and inferior cycling stability for MnO2 anode in lithium ion batteries, we present a highly flexible membrane employing two-dimensional (2D) reduced graphene oxide sheets (rGO) three-dimensional (3D) MnO2-reduced oxide-carbon nanotube nanocomposite (MGC) by vacuum filtration thermal annealing approach. All components 2D/3D thin film have synergistic effect on improved performance. The initial discharge specific capacity electrode with content 56...
Fabrication of a highly porous sulfur host and using excess electrolyte is common strategy to enhance utilization. However, flooded limits the practical energy density Li-S pouch cells. In this study, novel Fe0.34 Co0.33 Ni0.33 S2 (FCN) proposed as for realize Ah-level full cells demonstrating excellent electrochemical performances under 2 µL mg-1 lean conditions. Moreover, Kelvin probe force microscopy shows that FCN surface contains positive charge with potential ≈70 mV, improving binding...
Lithium secondary batteries have attracted considerable attention due to their great potential achieve ultrahigh energy density for future use. However, the Li metal anode suffers dendrite formation during repeated stripping/plating, hindering its practical realization. Herein, first time, an artificial solid electrolyte interphase layer, lithium phosphorus oxynitride (LiPON), is introduced anode, and viable application in high-energy pouch cell probed. LiPON stable with air, which can...
Polymer electrolytes have gained extensive attention owing to their high flexibility, easy processibility, intrinsic safety, and compatibility with current fabrication technologies. However, low ionic conductivity lithium transference number largely impaired real application. Herein, novel two-dimensional clay nanosheets abundant cation vacancies are created incorporated in a poly(ethylene oxide) (PEO)/poly(vinylidene fluoride-co-hexafluoropropylene)-blended polymer-based electrolyte. The...
The poor ambient ionic transport properties of poly(ethylene oxide) (PEO)-based SPEs can be greatly improved through filler introduction. Metal fluorides are effective in promoting the dissociation lithium salts via establishment Li-F bond. However, too strong interaction would impair fast migration ions. Herein, magnesium aluminum fluoride (MAF) fillers developed. Experimental and simulation results reveal that bond strength could readily altered by changing fluorine vacancy (V
A strategy for enabling a novel carbon fluoride (CFx) to be high-performance cathode material sodium batteries is proposed and realized. An amorphous highly disordered CFx, denoted as d-CFx, prepared through facile synthesis route. Herein we report on Na/d-CFx cell reversibly discharging/charging at such low overpotential capacity-decay rate. The polarization of the about 780 mV, lowest value reported in state-of-the-art Na/CFx system. initial discharge capacity 582.5 mA h/g, with 412.5 h/g...
