“…In addition, it was also shown that the current density increased at least two times in the composite fi ber compared to the undoped CNT fi ber (see Figure S10, Supporting Information). For both undoped CNT and composite NCNT fi bers, no characteristic electrocatalytic peaks at around -1.0 and -0.65 V for iron had been found, [ 26 ] which agrees with the energy-dispersive X-ray spectroscopy analysis. Therefore, the electrocatalytic performance mainly originates from the NCNTs in the composite fi bers and not as a result of trace iron.…”

“…The cell contains 2 mol dm ¹3 potassium hydroxide and 1 mol dm ¹3 lithium hydroxide aqueous solution as electro- lyte. 12 The performances of the Fe/nano-carbon composites were monitored by potentiostatic-chronoamperometric coupled measurement using a potentio-galvanostat (Solartron 1280). This measurement contains a polarization at ¹1.2 V during 30 minutes, and then the application of constant-current of 0.5 mA cm ¹2 until the potential of working reached at ¹0.2 V.…”

The influence of the sol-gel preparation condition of the composites of iron hydroxide with fibrous nano-carbon on their electrode properties has been investigated. The morphology, namely particle dispersion feature, of the Fe(OH) x /nano-carbon composites and their electrode properties depend on the preparation conditions, such as titration rate and the kind of alkali. The specific capacity of the composite with carbon nanotube substrate is approximately twice by that with vapor-grown carbon fiber substrate, due to smaller size of the pitches within entangled tubes.

Abstract. In this study, Acetylene Black (AB) and Fe 2 O 3 nanoparticles were used as the additive and active materials, respectively for preparing Fe 2 O 3 /AB composite electrode. The effects of carbon additive and binder content on the electrochemical properties of Fe 2 O 3 /AB electrodes in alkaline solution were investigated to find the suitable anode for the Fe/air battery. The results of electrochemical measurements showed that both the AB additive and binder content significantly affected on the electrochemical behaviors of Fe 2 O 3 /AB electrodes. AB additive improves in redox reaction of iron oxide. Increasing the binder content in electrode showed the negative effect in term of the cycleability of Fe 2 O 3 /AB composite electrode.
