Void‐Free Layered Polymeric Architectures via Capillary‐Action of Nanoporous Films - Lee - - Advanced Materials Interfaces - Wiley Online Library
Using carbon fiber (graphene?) thin films in composites (both in between the layers and the overwrap) to strengthen the composite, as running a current through the thin film causes a capillary action to squeeze out air voids and heat the resin for curing.

World première: Revolution in the underground car park – Volkswagen lets its charging robots loose | Volkswagen Newsroom
They split the charger from the robot now, so the robot tows the battery block with cable to an EV, plugs the cable in, then the robot rolls off alone to attend to other cars by dragging other battery units around.
