چکیده

intercalation of lithium into ag-cnts sample is reported here. we have used a nano-porous silver foam as a frame for deposition of the cnts   inside   the   pores   by   electrophoresis   deposition   (epd) technique. by using  chronopotentiometry method,  we  have noticed that the li storage capacity of the prepared ag-cnts electrode was improved  noticeably  in  comparison  with  literature.  in  addition,  a very  good functional stability  for  the  prepared  electrode  has  been tested   during   subsequent   cycles   of   charge / discharge   (c&d) procedures. by scanning the cycle's regulated current from 0.2 up to 1.0 ma , it was shown that in the range of 0.4–0.6 ma reversibility of the c&d capacity became optimum and the voltage profiles were converged, as well.

Li(V0.5Ti0.5)S2 as a 1 V lithium intercalation electrode

Graphite, the dominant anode in rechargeable lithium batteries, operates at ∼ 0.1 V versus Li(+)/Li and can result in lithium plating on the graphite surface, raising safety concerns. Titanates, for example, Li4Ti5O12, intercalate lithium at ∼ 1.6 V versus Li(+)/Li, avoiding problematic lithium plating at the expense of reduced cell voltage. There is interest in 1 V anodes, as this voltage is s...

Flame treatment of graphene oxides: cost-effective production of nanoporous graphene electrode for Lithium-ion batteries

A facile production of highly porous graphene foam by using flame treatment of graphene oxide (GO) is proposed. Highly porous architectures with randomly distributed micro-crack and micro-slit were produced due to the high temperature induced ruinous reduction and rapid expansion of GO. Synchronously, abundant oxygen-containing groups (OCGs) on GO sheets could be effectively removed after flame...

CNTs-COOH Paste Electrode for Detection of Temozolomide

The MWCNTs-COOH Paste Electrode (MCPE) was successfully used to study the electrochemical behavior of temozolomide in 0.2 M H2SO4 solution, phosphate buffer solution (0.1M PBS, pH 7.4) and 0.1M NaOH solution by Cyclic Voltammetry (CV) technique. The results exhibit that MCPE can remarkably enhance sensing and electrocatalytic activity towards the oxidation and reductio...

Electrode 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...
