Porous Mn2O3 microsphere as a superior anode material for lithium ion batteries

Abstract

Porous Mn 2 O 3 microspheres have been synthesized by morphology-controlled decomposition of spherical MnCO 3 precursors at 600 uC. The porous Mn 2 O 3 microspheres show a good rate capability and a high specific capacity of 796 mA h g 21 after 50 cycles.

Split-half-tubular polypyrrole@sulfur@polypyrrole composite with a novel three-layer-3D structure as cathode for lithium/sulfur batteries

“…Due to limited global energy supplies, environmental pollution, and the increasing consumption of energy, green and efficient energy storage devices are in high demand in modern society [1,2]. The lithium/sulfur battery is one of the most promising candidates, because the lithium/sulfur battery has the highest theoretical specific capacity of 1675 mAh g -1 among all the solid cathode lithium battery systems [3,4].…”

High performance pure sulfur honeycomb-like architectures synthesized by a cooperative self-assembly strategy for lithium–sulfur batteries

“…It is well known that compare to PEGDME 500 solvent, 1,3-dioxolane (DOL) and 1,2-dimethoxyethane (DME) have good ionic conductivity and low viscosity which is essential to enhance the high rate capabilities [1,2]. Thereby, in order to optimize the high rate behaviour of the honeycomb-like sulfur cathode, l mol/L lithium bistrifluoromethanesulfonamide (LiTFSI) in a mixed solvent of 1,3-Dioxolane(DOL) / 1,2-Dimethoxyethane (DME) (1 : 1 by volume) with 0.1 mol L -1 LiNO 3 as an additive was used as electrolyte to test the rate capabilities of the honeycomb-like sulfur cathode as well.…”

“…There has been no report on using soft template to prepare honeycomblike sulfur particles. 15 Clean and efficient energy storage devices are in high demand due to the limited global energy supply, environmental pollution, and the increasing consumption of energy 1,2 . The rechargeable lithium/sulfur battery has attracted significant attention due to its high theoretical specific capacity and power density [3][4][5][6][7][8] .…”

Mn2O3 Nanoparticles Synthesized from Thermal Decomposition of Manganese(II) Schiff Base Complexes

“…Manganese oxides are an important class of transition metal oxide family due to unique chemical and physical properties [8][9][10][11]. Among the different oxidation state of manganese oxides, Mn 2 O 3 nanoparticles are well-known as non-toxic, cheap, environmentally friendly and abundant and widely investigated as anode materials for lithium ion batteries because of their large theoretical specific capacities [12][13][14], catalyst [15,16] and hydrazine electrochemical sensing [17]. Recently, Mn 2 O 3 has been prepared by thermal decomposition of different manganese precursors [12,13,17,18], hydrothermal [14], solvothermal [16] and wet chemical approach [15].…”
