• Increased utilization of lead oxide core and increased electrode structural integrity. Abstract Graphene nano-sheets such as graphene oxide, chemically converted graphene and pristine graphene improve the capacity utilization of the positive active material of the lead acid battery.
The test results show that the low-temperature performance, charge acceptance, and large-current discharge performance of the batteries with graphene additives were significantly improved compared to the control battery, and the cycle life under 100% depth of discharge condition was extended by more than 52% from 250 to 380 cycles.
This study focuses on the understanding of graphene enhancements within the interphase of the lead-acid battery positive electrode. GO-PAM had the best performance with the highest utilization of 41.8%, followed by CCG-PAM (37.7%) at the 0.2C rate. GO & CCG optimized samples had better discharge capacity and cyclic performance.
The Fig. 6 is a model used to explain the ion transfer optimization mechanisms in graphene optimized lead acid battery. Graphene additives increased the electro-active surface area, and the generation of −OH radicals, and as such, the rate of −OH transfer, which is in equilibrium with the transfer of cations, determined current efficiency.
When this material is employed as the negative additive, the HRPSoC cycle life of lead-acid battery is tremendously prolonged by more than 224% from 8142 cycles to 26,425 cycles, which is also higher than that of the other two carbon additives.
