Zen, German Aerospace Center to develop graphene-enhanced aerogels for batteries

The goal of the project is to develop electrode materials for new generation batteries

“In November 2019, Zen reported on encouraging preliminary results on graphene-carbon aerogel battery development work which indicated that relatively low loadings (<5 wt.%) of graphene-based material, combined with DLR’s proprietary carbon aerogel structure, can result in an anode with a significant specific discharge capacity,” the company’s media brief states. “Preliminary best results were achieved with a 2 wt.% loading of graphene dispersed in aerogel and resulted in an initial specific discharge capacity of 2800 mAh/g and a discharge capacity of 1300 mAh/g after 50 cycles at a current capacity of 186 mA/g.”

According to the Canadian firm, these unoptimized results were believed to be better than those currently reported in the literature for graphene aerogel batteries. 

Graphene-enhanced aerogels could have the potential to be low-cost, low-weight, high-performance composite materials for near future energy storage applications.

Zen’s graphene is produced from Albany Pure Graphite which, in turn, is sourced from the company’s Albany deposit in Ontario, Canada.
