Wikipedia doesn't have a lot to say on their page for graphene applications:
Silicon-graphene anode lithium ion batteries were demonstrated in 2012.[126]

Stable Lithium ion cycling was demonstrated in bi- and few layer graphene films grown on nickel substrates,[127] while single layer graphene films have been demonstrated as a protective layer against corrosion in battery components such as the battery case.[128] This creates possibilities for flexible electrodes for microscale Li-ion batteries, where the anode acts as the active material and the current collector.[129]

Researchers built a lithium-ion battery made of graphene and silicon, which was claimed to last over a week on one charge and took only 15 minutes to charge.[130]

In 2015 argon-ion based plasma processing was used to bombard graphene samples with argon ions. That knocked out some carbon atoms and increased the capacitance of the materials three-fold. These “armchair” and “zigzag” defects are named based on the configurations of the carbon atoms that surround the holes.[131][132]
a look at trade magazines doesn't turn up a lot.
Didn't find anything about graphene batteries at Electronics Weekly.
Electronics Design did have an article talking about the benefits of wrinkled graphene for battery electrodes. This was more of an article about some quirky research that will likely never get to production rather than something with immediate and obvious benefits.

That doesn't mean that there aren't products with "graphene!" on the label. No idea if there is actually any graphene in the battery, though.
When a major manufacturer is producing a graphene battery with a data sheet that shows distinct benefits.... then I'll start thinking about buying one.
