Supercapacitor for storage, high power, and fast charging of EVs - Penn State University
Objective/theme
A new supercapacitor based on manganese oxide could combine the storage capacity of batteries with the high power and fast charging of other supercapacitors.
Process & benefits
Manganese oxide is definitely a promising material, by combining with cobalt manganese oxide, it forms a heterostructure in which we are able to tune the interfacial properties.
Exploring manganese oxide with cobalt manganese oxide as a positive electrode and a form of graphene oxide as a negative electrode yields an asymmetric supercapacitor with high energy density, remarkable power density, and excellent cycling stability.
The group has compared their supercapacitor to others and theirs has much higher energy density and power. They believe that by scaling up the lateral dimensions and thickness, their material has the potential to be used in electric vehicles.
