The graphene cathode development startup Volexion has secured over $1 million in funding, with the intent of increasing production of their graphene coating for lithium-ion cathodes. The company has plans to increase production to “several kilograms [s]” of batch capacity.
The cathode material in question is meant to increase power density, electric density, and double the running time.
A spokesman for Volexion said the following; “We tested rate capability of the material. Power density is a consequence. The rate capability was 5x higher for coated versus uncoated, translating into 40% higher power density at the cell level, without any battery optimization. This specific test was 3x improvement -> Uncoated cells reached 80% capacity(i.e., failed), and the coated cells reached 80% capacity. The same cell reached >1,000 cycles under even more demanding conditions”.
