The supercapacitor market is set to take off, and graphene could play a center role
Analysts from IDTechEx estimate that the global supercapacitor market is around $1.5 billion in annual sales, following several years of decline. IDTechEx, however, believes the market bottomed out in 2018-2019 and is set now for a sustained period of strong growth.
Allied Market Research, supercapacitor market 2016-2022
IDTechEx explains that the market is expected to grow quickly in the coming years, as companies are expected to increase the use of supercapacitors over batteries in electric and hybrid cars as the customers are seeking faster charging and safer transport. Allied Market Research estimates that the Supercapacitor market will grow at a CAGR of 28.7% from 2016 to 2022 and will reach $6.3 billion in 2022, while India-based also sees a fast growth rate of 22% from 2016 to 2022, and estimates a $4 billion market in 2022. Both market research companies did not see the down year in 2016-2019, but it is still interesting to note these market forecasts.
Market Research Future, Supercapacitor revenues, 2016-2022
IDTechEx says that there are two primary limitations that hold back wider adoption of supercapacitors - energy density and price. But these issues will be largely overcome in the future. IDTechex says that market trends to fastest charging, providing pulse power, safe transport, no expensive materials and no issues of disposal are increasingly favouring supercapacitors over batteries.
Graphene has great potential for the supercapacitor market as one of the next-generation materials that are set to overcome the energy density problem. In fact supercapacitors is one of the first markets that successfully adopts graphene commercially.
Skeleton Technologies, for example, is already offering a wide range of supercapacitor cells and modules, and the company has various projects in the pipeline. For example, in September 2018, Skeleton and British bus manufacturer Wrights Group announced the signing of a high-volume, multi-million-euro contract for the next 5 years. Skeleton Technologies will supply graphene-based supercapacitors to the latest KERS enabled hybrid-electric double and single deck buses produced by the Wrights Group. With Skeleton Technologies’ supercapacitors, Wrightbus operators will also be cutting down on maintenance costs; While the lithium battery may last around 4 to 5 years, during their 1 million cycles, the supercapacitors will reportedly last for at least 7.5 years, with an estimated life of 12 to 15 years.
A study led by the US Naval Surface Warfare Center in Philadelphia, along with researchers at the University of Texas at Arlington, has compared the performance of supercapacitors from four different manufacturers: Maxwell, Ioxus, JM Energy, and Skeleton. Of the four tested, only the Skeleton supercapacitors are graphene-enhanced, and the researchers found that the Skeleton cell far outperformed the other cells tested, and graphene was mentioned as the probable cause for this efficiency.
In China, many companies are working to develop graphene supercapacitors, and some display impressive preliminary success – like GMCC, that offers such products for sale.
