Synthesis and Electrochemical Property of LiMn2O4 Porous Hollow Nanofiber as Cathode for Lithium-Ion Batteries
The LiMn2O4 hollow nanofibers with a porous structure have been synthesized by modified electrospinning techniques and subsequent thermal treatment. The precursors were electrospun directly onto the fluorine-doped tin oxide (FTO) glass. The heating rate and FTO as substrate play key roles on preparing porous hollow nanofiber. As cathode materials for lithium-ion batteries (LIBs), LiMn2O4 hollow...
متن کاملSynthesis of Hard Carbon- Silicon Nanocomposite as Anode Active Material for Lithium-Ion Batteries
In this research, using phenolic resin as the precursor of carbon and various amounts of ethylene glycol as a pore former, porous samples of hard carbon were synthesized. Samples were characterized by x-ray diffraction (XRD) and N2 adsorption-desorption methods. Broad diffraction peaks represent the amorphous structure of samples. Moreover, the gas adsorption-desorption curves showed that the a...
متن کاملElectrode Materials for Lithium Ion Batteries: A Review
Electrochemical energy storage systems are categorized into different types, according to their mechanisms, including capacitors, supercapacitors, batteries and fuel cells. All battery systems include some main components: anode, cathode, an aqueous/non-aqueous electrolyte and a membrane that separates anode and cathode while being permeable to ions. Being one of the key parts of any new electr...
متن کاملElectrochemical Investigations of Cobalt-Doped LiMn2O4 as Cathode Material for Lithium-Ion Batteries
A wide range (y = 0.05—0.33) of Co-doped LiCo5Mn2_504 spinels were synthesized and electrochemically characterized. These Co-doped spinels showed improved specific capacity and capacity retention over pure spinels. Electrochemical impedance spectroscopy and the linear polarization resistance technique were used to determine the transport and electrochemical kinetic parameters of Co-doped spinel...
متن کاملNanostructured LiMn2O4 prepared by a glycine-nitrate process for lithium-ion batteries
Porous nanostructured spinel LiMn2O4 has been successfully synthesized using a glycine-nitrate combustion process. The average primary particle size of the as-synthesized powders was about 10 nm, but increased to about 100 nm with improved crystallinity after calcination at 800 jC for 2 h. Yet, the calcined powders were still highly porous and displayed reversible capacity of about 112 mA h g 1...
