Art style: Cyberpunk.
A shadowy boardroom. The silhouetted figures of powerful corporate executives sit around a large, polished table. In the center of the table, a glowing hologram of the graphene battery is projected. One of the figures makes a sharp, dismissive gesture towards the hologram.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cyberpunk" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cyberpunk". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cyberpunk" idiom, not in any other medium.
