Although solid-state graphene batteries are still years away, graphene-enhanced lithium batteries are already on the market. For example, you can buy one of Elecjet''s Apollo batteries, which have graphene components that help enhance the lithium battery inside. The main benefit here is charge speed, with Elecjet claiming a 25-minute empty-to
The PSoC operation mode would easily lead to sulfation, where low solubility PbSO<sub>4</sub> crystals progressively replace battery active materials and impede conductive network pathway resulting in limited cycle life. One of the main strategies to suppress sulfation is through adding different forms of carbon additives into the negative

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.
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.
By comparing the values of Rct as calculated from the fitted equivalent circuit, the 3D-RGO sample (5.661 Ω) exhibits significantly lower charge transfer in comparison to AC (16.28 Ω) and ACET (17.20 Ω), which indicates that graphene with rich pores structure could improve the kinetics of battery reaction when employed as additive.
