How about the new Leona Migao carbon battery?

Good quality. The new Li Nuo high-carbon battery is graphene battery, ranking the top three in China. Many of Tianneng's products are made in Li Nuo, with good quality and the biggest feature is large capacity. It is a new energy battery developed by using the characteristics of lithium ion shuttling quickly and massively between graphene surface and electrodes. It is a honeycomb planar film formed by the hybridization of carbon atoms sp2, and it is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monoatomic graphite.
