Biomass-based nanofibers were prepared by electrospinning a mixture of polyacrylonitrile and acid-treated biomass from industrial hemp straw. The as-prepared biomass-based nanofibers were then carbonized and activated by high-temperature carbonization and KOH to obtain the activated biomass-based carbon nanofibers. The scanning electron microscopy images show that the precursors and carbon nanofibers...
In this paper, a highly-active cobalt oxide (CoO) nanospheres catalyst has been synthesized by DC arc discharge plasma method and used as air electrode for lithium oxygen battery. Through scanning electron microscopy (SEM) observation, the particle size of the cobalt oxide (CoO) catalyst can be controlled between 40~60 nm and dispersed uniformly into the active material. And then the cobalt oxide...
Bipolar lead-carbon battery is a novel lead-carbon battery. Its greatest advantage is the carbon electrode can be combined with lead active material and freely distribute. In addition, the proportion of carbon material can be easily enhanced. In this paper, two types of bipolar lead-carbon batteries are prepared. One is Pb-C electrodes as negative plates (type 1 battery) and the other is Pb-C electrodes...
Tetrabasic lead sulfate (4BS) is a common positive active material additive for lead-acid battery. It is used for inhibiting positive active material softened in order to improve its cycle life. In this paper, we synthesize a type of micro/nanostructure 4BS via sol-gel method and analyze the electrochemical performances of the positive active material for the lead-acid battery after adding the additive...
Under an aid of ultrasonic, tetraoxalyl ethylenediamine melamine resin-coated multiwalled carbon nanotubes were prepared for Ni(II) sensing in aqueous solution. The processes involved the fabrication of tetraoxalyl ethylenediamine melamine resin by one pot way, the coating of tetraoxalyl ethylenediamine melamine resin at multiwalled carbon nanotubes (MWCNTs), and the determination of Ni(II). The present...
