German researchers develop aerographite; lightest material yet has potential application in electrodes

Researchers from the Technical University of Hamburg and the Christian-Albrechts-University of Kiel have jointly developed an ultra-lightweight carbon microtube material called Aerographite. The material—currently the lightest known, features a hierarchical design enabling ”remarkable” mechanical, electrical, and optical properties, the authors said in a paper published in the journal Advanced Materials.

These SEM results depict the intact and fractured junctions of hollow graphitic shells. SEM shown here originate from 3 different CVD-processes and template morphologies. Future experiments will also investigate the influence of bridging density on mechanical and electrical properties of Aerographite. Credit: Mecklenburg et al. Click to enlarge.

The first experiments with Aerographite electrodes confirm its applicability.

The material is synthesized using a novel single-step chemical vapor deposition synthesis based on ZnO networks.

This could be an import step towards lighter higher performance future EV batteries, specially for larger (100 Kwh) units required for long range EV limos.
