With the increasing applications of Lithium-ion batteries in heavy equipment and engineering machinery, requirements rate capability are continuously growing. The high-rate performance Li4Ti5O12(LTO) needs to be further improved. In this paper, we synthesized LTO microsphere-TiO2(B) nanosheets (LTO-TOB) composite by using a solvothermal method subsequent calcination. LTO-TOB combines merits TiO2(B) LTO, resulting excellent (144.8, 139.3 124.4 mAh g-1at 20 C, 30 C 50 C) superior cycling...
Ti 2 [Formula: see text][Formula: text] (TNO) is considered as a potential anode material due to its high capacity/power density and reliable safety. However, poor electronic conductivity restricts rate performance, which important for application in electric vehicles (EVs). In this study, we fabricated hybrid of text]/holey-reduced graphene oxide (TNO x /HRGO) by two-step method. the structure TNO /HRGO, microspheres with oxygen vacancies are wrapped gossamer-like HRGO. The HRGO can...
Titanium niobium oxides (TNOs), benefitting from their large specific capacity and Wadsley-Roth shear structure, are competitive anode materials for high-energy density high-rate lithium-ion batteries. Herein, carbon oxygen vacancy co-modified TiNb6O17 (A-TNO) was synthesized through a facile sol-gel reaction with subsequent heat treatment ball-milling. Characterizations indicated that A-TNO is composed of nanosized primary particles, the content about 0.7 wt%. The nanoparticles increase...
Abstract In this work, monophasic Sn 3 O 4 and biphasic -SnO 2 heterostructure composed of plentiful nanosheets were synthesized by using a simple one-step solvothermal method. Their morphology, structure, composition characterized XRD, XPS, SEM TEM. Also their NO sensing performance tested systematacially. The results demonstrated that the gas sensor based on composites exhibits excellent including low operating temperature, high sensitivity outstanding selectivity. Its to 1 ppm is as...
