Improving performance of lead-acid batteries through carbon lead hybrid electrodes

Truong Van Men, . and Duong Ngoc Bich, . and Dien Tran Van, . and Banh Huynh Thanh, . Improving performance of lead-acid batteries through carbon lead hybrid electrodes. pp. 91-102. ISSN 2672-7226

This paper presents the study of the addition of carbon materials to negative electrodes to upgrade the performance of lead-acid batteries through avoiding sulfation and getting super capacitance effects due to their high specific surface area. Two kinds of carbon materials including carbon fibre paper and activated carbon cloth with high electrical conductivity and porosity are selected in the experiments. The required hydrophilicity of the carbon materials is pretreated and checked through the surface contact angle measurement before added. The surface morphology of carbon materials negative electrodes are also observed using Scanning Electron Microscope. The results show that the performance of the carbon-added battery cells is improved. The initial capacity and specific energy of the tested battery cells with the carbon cloth addition are about 15 higher than those of battery cells without the carbon addition. Moreover the lead sulphate crystal size formed on the negative electrode surfaces of the carbon added batteries are smaller than that on the negative electrode surfaces of the conventional batteries revealing that carbon addition can improve the battery lifespan.

Abstract

This paper presents the study of the addition of carbon materials to negative electrodes to upgrade the performance of lead-acid batteries through avoiding sulfation and getting super capacitance effects due to their high specific surface area. Two kinds of carbon materials including carbon fibre paper and activated carbon cloth with high electrical conductivity and porosity are selected in the experiments. The required hydrophilicity of the carbon materials is pretreated and checked through the surface contact angle measurement before added. The surface morphology of carbon materials negative electrodes are also observed using Scanning Electron Microscope. The results show that the performance of the carbon-added battery cells is improved. The initial capacity and specific energy of the tested battery cells with the carbon cloth addition are about 15 higher than those of battery cells without the carbon addition. Moreover the lead sulphate crystal size formed on the negative electrode surfaces of the carbon added batteries are smaller than that on the negative electrode surfaces of the conventional batteries revealing that carbon addition can improve the battery lifespan.
