The graphene hype cycle is completing its second full rotation

Remember when graphene was going to replace every material? Stronger than steel! Thinner than an atom! Going to revolutionize batteries, screens, packaging, structural composites, electronics — everything, simultaneously, by 2020!

I'm not being dismissive. The properties are real. The problem was always the gap between "we made one perfect layer in a lab" and "we manufactured a billion of them consistently and integrated them into products." That gap turns out to be enormous.

What I find interesting now is watching which applications are actually making it through the scaling problem versus which ones are still "five years away."

Battery electrode additives: genuinely commercial, modest improvement, real.
Flexible electronics: still mostly research-stage for true single-layer applications.
Structural composites: graphene-enhanced versions exist, but mostly graphite nanoplatelets, not true graphene.

The pattern is familiar from carbon fiber, which also went through a long period between "lab-proven superior material" and "practical, scalable product." Carbon fiber eventually found its niches (aerospace, high-end vehicles, sporting goods) and became genuinely valuable there.

I'd guess graphene follows the same path — specific high-value niches where the scaling problem is manageable and the performance advantage justifies the cost. Not everything. But some things.

Anyone working in materials science here who's seen specific applications that feel genuinely close to practical deployment?
