It reveals the performance, formulation and morphology of the key materials used and those planned for the future. The report embraces work both by the device manufacturers and by the many third party developers and suppliers of the key functional materials across the world.
The structure of a supercapacitor and supercabattery is introduced together with the materials and parameters needed for the applications with the greatest business potential. It focusses on the primary market need for the future – lower cost with higher energy densityA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitorsA figure of merit usually expressed in Joules per cubic inch for capacitors. The materials are assessed and progress reported and predicted. That means electrodeA solid electric conductor through which an electric current enters or leaves in a medium and then electrolyte materials, with separators third in importance. For electrodes, that includes many types of grapheneGraphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice., carbon nanotubes, nano-onions, aerogels and chemically-derived carbons. Important for future electrolyte needs are new neutral aqueous electrolytes permitting low cost current collectors now with higher voltage, new ionic liquids that work at low temperatures and new organic solvents – less toxic and non-flammable.
For electrodes, the various hierarchical (wide to narrow pores in bulk), exohedral (large area allotropes) and thin film options are compared. They are related to various end points from micro-supercapacitorsUnconventional internal design yields a larger capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors.

In addition they will replace inverter capacitors and be even more useful in many other EV locations including regenerative braking backup and bus door opening.

IDTechEx shows which electrodeA solid electric conductor through which an electric current enters or leaves in a medium functional materials best leverage the next-generation electrolytes so toxicity and flammability will be a thing of the past. Key players are identified and their plans revealed based on a host of ongoing interviews.
