Graphene MesoSponge® (GMS), the next-generation carbon material that 3DC plans to mass-produce, was featured as a promising cathode material for lithium-air batteries in Nikkei Online on January 25 and in the morning edition of Nikkei newspaper (national edition) on January 26.
The article introduces the research achievements of the Nishihara Laboratory (Advanced Institute for Materials Research, Tohoku University), where GMS was invented. We highly recommend reading it.
For research on the use of GMS as a cathode material for lithium-air batteries, see also the following.
