“…In addition, it seemed difficult to uniformly apply battery pastes on the foam due to the small pores in the cell walls of the foam material. In our previous work, a new pitchbased carbon foam with large pores in the cell walls was developed and investigated as current collectors for lead acid batteries [14]. Cyclic voltammetry studies showed that the carbon foam was suitable for use as negative current collectors for lead acid batteries.…”

Pitch-based carbon foams prepared by a template method were used as negative current collectors to assemble flooded lead acid batteries, and the effect of the current collectors on the performance of the negative electrodes was investigated. Comparative galvanostatic charge-discharge tests show that the utilization efficiencies of the active material on the carbon foam negative current collector are 14% and 30% higher than those of the material on a lead grid one at 20 and 10 h discharge rates, respectively. Further EIS tests imply that there are also significant differences in the impedance spectra between the two electrodes. SEM images reveal that at the fully charged state, the particle size of the active material formed on the carbon foam current collector is much more uniform than that on the lead grid.

“…The heavy weight is a direct result of the use of large amounts of lead in the electrodes, both in the grids and in the active materials [4]. To improve the specific energy, lightweight, electronically conductive materials have been proposed as potential substitutes for lead alloy grids [4][5][6][7][8][9][10][11][12][13][14].…”

“…The carbon foam (CFoam), a lightweight material, threedimensional network with open cell structure, large specific surface area, thermally and electrically conductive along with good corrosion resistance, is a promising candidate for current collector for lead acid batteries (Jang et al 2006;Chen et al 2008). The electrical conductivity of CFoam derived from different organic and inorganic precursors can be tailored by controlling processing parameters.…”

In the present study, nanostructuring effect of multi-walled carbon nanotubes (MWCNTs) on electrochemical properties of coal tar pitch (CTP) based carbon foam (CFoam) was investigated. The different weight fractions of MWCNTs were mixed with CTP and foam was developed from the mixture of CTP and MWCNTs by sacrificial template technique and heat treated at 1,400 and 2,500°C in inert atmosphere. These foams were characterized by scanning electron microscopy, X-ray diffraction, and potentiostat PARSTAT for cyclic voltammetry. It was observed that, bulk density of CFoam increases with increasing MWCNTs content and decreases after certain amount. The MWCNTs influence the morphology of CFoam and increase the width of ligaments as well as surface area. During the heat treatment, stresses exerting at MWCNTs/ carbon interface accelerate ordering of the graphene layer which have positive effect on the electrochemical properties of CFoam. The current density increases from 475 to 675 mA/cm 2 of 1,400°C heat treated and 95 to 210 mA/cm 2 of 2,500°C heat-treated CFoam with 1 wt% MWCNTs. The specific capacitance was decreases with increasing the scan rate from 100 to 1,000 mV/s. In case of 1 % MWCNTs content CFoam the specific capacitance at the scan rate 100 mV/s was increased from 850 to 1,250 lF/cm 2 and 48 to 340 lF/cm 2 of CFoam heat treated at 1,400°C and 2,500°C respectively. Thus, the higher value surface area and current density of MWCNTs-incorporated CFoam heat treated to 1,400°C can be suitable for lead acid battery electrode with improved charging capability.
