چکیده

Vanadium pentoxide (V2O5)-anchored single-walled carbon nanotube (SWCNT) composites have been developed through a simple sol–gel process, followed by hydrothermal treatment. The resulting material is suitable for use in flexible ultra-high capacity electrode applications lithium-ion batteries. unique combination of V2O5 with 0.2 wt.% SWCNT offers highly conductive three-dimensional network. This ultimately alleviates the low intercalation seen itself and facilitates vanadium redox reactions. integration SWCNTs into layered structure leads to high specific 390 mAhg−1 at 0.1 C between 1.8 3.8 V, which close theoretical (443 mAhg−1). In recent research, most carbonaceous materials shows higher but limited cyclability poor rate capability. this work, good only 0.3% per cycle degradation during 200 cycles enhanced capability 178 10 achieved. excellent electrochemical kinetics lithiation/delithiation attributed chemical interaction entrapped layers nanostructured Proper dispersion structure, its effects, validated SEM, TEM, XPS, XRD, electrical resistivity measurements. innovative hybrid new direction large-scale production high-performance cathode advanced structural battery applications.

Synthesis of Microspherical LiFePO4-Carbon Composites for Lithium-Ion Batteries

This paper reports an "all in one" procedure to produce mesoporous, micro-spherical LiFePO₄ composed of agglomerated crystalline nanoparticles. Each nanoparticle is individually coated with a thin glucose-derived carbon layer. The main advantage of the as-synthesized materials is their good performance at high charge-discharge rates. The nanoparticles and the mesoporosity guarantee a short bulk...

Partially crystalline Zn₂GeO₄ nanorod/graphene composites as anode materials for high performance lithium ion batteries.

Zn2GeO4 nanorod/graphene composites (ZGCs) were yielded by a two-step hydrothermal processing. Crystalline and amorphous regions were found to coexist in a single Zn2GeO4 nanorod. The surface of the Zn2GeO4 nanorod was compactly covered and anchored by graphene sheets. The ZGCs were then utilized as anodes for lithium ion batteries (LIBs). Intriguingly, partially crystalline ZGC containing 10.2...
