In this article, we report the addition of graphene (Gr) to negative active materials (NAM) of lead-acid batteries (LABs) for sulfation suppression and cycle-life extension. Our experimental results show that with an addition of only a fraction of a percent of Gr, the partial state of charge (PSoC) cycle life is si
However, every type of carbon material has a different impact. Furthermore, the mechanism of performance improvement must be clarified. In the present work, graphene was added into a negative active material (NAM) used in a battery cell. The cell was tested under a partial state of charge condition at an extreme discharge cycle.
Vangapally et al. studied the use of boron-doped graphene nanosheets (BGNS) as a lead-acid battery negative electrode additive to reduce the HER of the negative electrode and inhibit sulfation.
The lead acid battery comprises a battery shell, a positive plate grid, a negative plate grid, a partition board and electrolyte, wherein the positive and negative plate grids are positioned in the battery shell; the partition board is positioned between the positive and negative plate grids; and the electrolyte is filled into the shell.
Discharge voltage of the battery with and without graphene during the cycling test. The PSOC test was performed at a constant current of 600 mA for 60 s. The cut of voltage was 1.7 V. CV graph of the negative plate with and without graphene before the PSOC test. The scan rate during the CV test was 1.5 mV/s.
3.2. Electrochemical performance of the plate When the lead-acid battery is in a charged state, hydrogen evolution occurs at the negative electrode, which may cause the electrolyte of the lead-acid battery to dry up, thereby shortening the cycle life of the battery .
