Sheet-like structure FeF3/graphene composite as novel cathode material for Na ion batteries

TL;DR: In this article, a sheet-like structure FeF3/graphene composite is successfully synthesized by a novel and facile sol-gel method, and the structure and electrochemical performance of the as-synthesized composite are investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) and Electrochemical measurement.
Journal ArticleDOI

Spherical concentration-gradient LiMn1.87Ni0.13O4 spinel as a high performance cathode for lithium ion batteries

TL;DR: LiMn1.87Ni0.13O4 as discussed by the authors was successfully synthesized via a co-precipitation route, in which the homogeneous LiMn2O4 core is encapsulated by a continuously Ni increasing concentration-gradient layer, and the composition of the outmost layer of the spherical LiMmn 1.87 Ni0.5O4 sample has a typical Fd3m spinel structure.
Journal ArticleDOI

Iron fluoride with excellent cycle performance synthesized by solvothermal method as cathodes for lithium ion batteries

TL;DR: In this paper, a hollow prismatic/cylindric iron fluoride with a wall thickness of 0.5μm and a length of 1-3μm has been synthesized by a simple and mild solvothermal method.
Journal ArticleDOI

Spherical lithium-rich layered Li1.13[Mn0.534Ni0.233Co0.233]0.87O2 with concentration-gradient outer layer as high-performance cathodes for lithium ion batteries

TL;DR: A spherical lithium-rich layered cathode material with an average composition of Li 1.13 [Mn 0.534 Ni 0.233 Co 0.87 O 2 ] was successfully synthesized via co-precipitation route as discussed by the authors.
Journal ArticleDOI

The electrochemical performance and mechanism of cobalt (II) fluoride as anode material for lithium and sodium ion batteries

TL;DR: In this article, a reversible interfacial intercalation mechanism was discovered for cobalt (II) fluoride electrode material, which contributes a combined discharge capacity of about 400 mAhg−1 with the formation of SEI film at the initial discharge process.
