Integrated Co3O4/carbon fiber paper for high-performance anode of dual-ion battery

FeMnO3: a high-performance Li-ion battery anode material.

In this communication, FeMnO3 particles were prepared and evaluated as an anode material for Li ion batteries. This electrode shows high capacity, excellent rate capability, and good cycling stability (984 mA h g-1 at 1.0 A g-1 after 500 cycles). Moreover, the Li storage mechanism is studied.

Crumpled graphene paper for high power sodium battery anode

Graphene-based electrodes typically form a compact uniaxially oriented stacked structure during electrode preparation due to the highly anisotropic morphology. This leads to limited diffusion paths for the insertion of Li or Na when used as electrodes in rechargeable batteries. Here, we demonstrate that selfstanding electrodes formed of randomly folded and/or crumpled graphene nanosheets can be...

A high performance lithium-ion battery using LiNa0.02K0.01FePO4/C as cathode material and anatase TiO2 nanotube arrays as anode material

In this paper we report on a lithium ion battery (LIB) based on improved olivine lithium iron phosphate/carbon (LiFePO4/C) as cathode material and LiNa0.02K0.01FePO4/C  synthesized by sol-gel method and TiO2 nanotube arrays (TNAs) with an anatase phasesynthesized through anodization of Ti foil as an anode electrode. Crystallographic structure and surface morphology of the cathode and anode mate...

Solid-State Fabrication of SnS2/C Nanospheres for High-Performance Sodium Ion Battery Anode.

Tin disulfide (SnS2) has emerged as a promising anode material for sodium ion batteries (NIBs) due to its unique layered structure, high theoretical capacity, and low cost. Conventional SnS2 nanomaterials are normally synthesized using hydrothermal method, which is time-consuming and difficult to scale up for mass production. In this study, we develop a simple solid-state reaction method, in wh...
