2D R2R carbon nanomembranes to suppress dendrite growth in solid state batteries

Solid-State-Batteries with metal (e.g., Li) anodes have the potential to dramatically increase the energy density of batteries beyond what standard Li-ion batteries can do. In electric vehicles, this could boost driving range to 700-800Km! A well-known technology challenge is excessive dendrite growth, shortening cell lifespan and perhaps even compromising safety by causing short circuits.


In this post, @Albert Schneiders from @CNM Technologies offers a potential solution based on R2R-manufactured 2-dimensional insulating carbon nano-membranes. All the details will be presented at TechBlick’s event on (a) Frontier Battery Materials and (b) Solid-State Battery Materials on 15-16 Feb 2023 online. https://www.techblick.com/event/solidstatebatteries


✔️ Helium ion microscopy image of freestanding CNMs over a copper grid. These materials are insulating and are shown to conduct Li ions. They have potential to be manufactured at scale using R2R processes

✔️ Measurement data showing that the insertion of a 2D carbon nanomembrane can double the lifetime of a symmetric Li coin cell!!

This technology could be applied to:

▶️ Liquid electrolyte/quasi solid state electrolytes as a functional layer over a conventional separator facing metal anode

▶️ Solid state electrolytes over ceramic solid state electrolytes to improve the ionic conductivity at the interface

▶️ Artificial SEI as an artificial solid electrolyte interface on Cu electrode enabling anodeless metal batteries

These results and much more will be presented at TechBlick’s event on (a) Frontier Battery Materials and (b) Solid-State Battery Materials on 15-16 Feb 2023 online.
