"Supercapacitor Materials 2017-2027", explains how, out of the spotlight, very important advances are occurring even beyond market leader Maxwell's superlative opening up of new applications with tailored products. In the desert for supercapacitor manufacture - Europe - Skeleton Technologies has started to make supercapacitors partially based on graphene that set the record for power density and Yunasko in the Ukraine set the record for production hybrid supercapacitor energy density - up near lead acid and NiCd batteries and something Nippon Chemical says it will match next year.
The report has a global sweep. From ongoing visits, it explains how, recognising the distaste of the Japanese motor industry for highly toxic electrolytes, Nippon Chemical in Japan jumped from nowhere to number two in supercapacitors in the world by making supercapacitors for cars that had benign electrolytes. "Supercapacitor Materials 2017-2027" expresses the view that, partly because its supercapacitor suppliers have become more capable, China has recently reversed its policy on traditional hybrid vehicles, declaring that in 2030, 30% of cars made would be hybrids that do not plug in - candidates for supercapacitors. With GM now adopting them, supercapacitors are rapidly taking market share of stop-start systems for conventional vehicles.
"Supercapacitor Materials 2017-2027" finds that electrolytes with totally new chemistry are pairing well with new exohedral active electrodes. Hybrid capacitors are benefitting from totally new electrolyte-electrode pairings in the laboratory at least. Are the old rules of extremely hydrophobic assembly following complex high temperature processes really necessary for best performance? Everything is being questioned now.
Learn how, in 2016-7, researchers at MIT and elsewhere developed a supercapacitor using no conductive carbon that will potentially store much more power. Learn how the British have entered the fray, announcing new large molecule electrolytes based on large organic molecules composed of many repeated sub-units and bonded together to form a 3-dimensional network. Appraise the opportunity to match lithium-ion battery energy density without the short cycle life, poor power density and safety issues of a battery. Are we going to have "batteries" that can be fully discharged for safe transit and safe retrieval in a car crash unlike real Li-ion batteries?
Learn how, in three countries, researchers are making supercapacitors that are load-bearing structures and others demonstrate stretchable supercapacitor fibers being woven, things batteries cannot do even when solid state because they swell and shrink on cycling. Other old certainties are being questioned as well, each advance potentially opening up large new applications. A multibillion dollar market for the materials is in prospect but not overnight. Now is the time to investigate and invest and the report, "Supercapacitor Materials 2017-2027" goes right to the added value emerging.
