Electrochemical Control of Lithium-Ion Batteries
Batteries help advance technologies ranging from portable electronics to renewable power systems and environmentally friendly vehicles. One such technology is the hybrid electric vehicle (HEV), which uses a battery and an electric motor in conjunction with a combustion engine to increase fuel effi ciency. For HEV applications, nickel metal hydride (Ni-MH) battery chemistry is presently the norm...
متن کاملUltrafine tin nanocrystallites encapsulated in mesoporous carbon nanowires: scalable synthesis and excellent electrochemical properties for rechargeable lithium ion batteries.
A morphology-conserved transformation yields Sn@C nanowires (UTP@CW, ∼21 wt% carbon and ∼77 wt% tin) with a high encapsulation density of ultrafine tin nanoparticles in porous carbon nanowires, which exhibit excellent reversible capacities and cycling performance for lithium ion batteries, especially at high current rates.
متن کاملElectrochemical Evaluation of PbO Nanoparticles as Anode for Lithium Ion Batteries (Technical Note)
PbO nanoparticles were synthesized using hydrothermal process. Scanning electron microscopy (SEM) was used in order to investigate of PbO powders. X-ray diffraction (XRD) pattern confirmed β-PbO formation during this process. The crystallite size of the powders was calculated using Scherrer formula about 74.6 nm. Electrochemical evaluation of the PbO nanoparticles as anode for Li-ion batteries ...
متن کاملElectrochemical properties of boric ester electrolytes with high potential cathode for lithium ion batteries
Introduction Lithium-ion batteries are currently produced on a large scale mainly as equipment for powering portable electronic devices, but simultaneously intensive research is carried out on the development of large and high power batteries for powering hybrid electric vehicles (HEVs) and plug-in HEVs. We have reported that boric ester electrolytes showed the high oxidation potential. Boric e...
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...
