Abstract
In this article, different carbon materials (NC, CC) are obtained by burning two kinds of six‐carbon alkane, n‐hexane, and cyclohexane, respectively. They are used as negative electrode additives for lead‐carbon batteries (LCBs) that could considerably improve the performance of LCB cycle life. 0.1 wt% NC (0.1NC) shows the best high rate partial state of charge cycle performance (5350) which is 3.6 times of CC and 1.2 times of commercial conductive carbon black. Furthermore, in the charging acceptance test, the initial instantaneous constant voltage charging receiving current of 0.1NC is 7.81 A, which is increased by 167% compared with 0.1EC (2.92 A). The synergistic effect of high graphitization structure, small specific surface area, and abundant carboxyl functional groups may be the reason for NC's good performance.
