Abstract

Bamboo carbon decomposed by low temperature has a high surface area and contains micro-holes; it belongs to one of the amorphous carbon materials. Due to the large lithium storage space and high discharge performance rate, lithium batteries enjoy high power consumption. However, there are also some defects of the first higher irreversible capacity and voltage delay. In this study, a natural bamboo carbon powder was used as an experimental material. After adding AgNO3 and treating the surface with heat at 450 and 650°C, fine Ag/AgCl phases are coated on the surface of carbon powders. C-Ag and C-AgCl are formed to increase the capacity and reduce the first irreversibility. Also, the concentration of Ag on the carbon surface increased with the increment of temperature from 450 to 650°C. This not only increased the conductivity but also enhanced the surface bonding of CAg powders to promote the performance of chargedischarge cycles.
