Next Supercapacitor Advances Will Transform Electric Vehicles Report IDTechEx

The new IDTechEx report “Functional Materials for Supercapacitors / Ultracapacitors / EDLC 2015-2025” www.idtechex.com/scmats explains the materials and performance, achievements and objectives of the 80 manufacturers of supercapacitors and supercabatteries and researchers.

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 density. The materials are assessed and progress reported and predicted. That means electrode and then electrolyte materials, with separators third in importance. For electrodes, that includes many types of graphene, 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-supercapacitors to structural ones forming part of a building, smart skin on ships or e-fibers in textiles. Emerging, there is a wealth of different needs for high added value functional materials.

The material needs of large supercapacitors appearing in electric vehicles are the main focus – primarily partly or wholly replacing traction batteries. 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.

For example, IDTechEx forecasts the best energy density that will be achieved in volume production in the next 15 years, the best candidate materials, capacitor structures and electrolytes for achieving this and the value market resulting.

IDTechEx shows which electrode 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.

Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
The many IoT deployments around the world are busy integrating smart devices and sensors into their enterprise IT infrastructures. Yet all of this technology – and there are an amazing number of choices – is of no use without the software to gather, communicate, and analyze the new data flows. Without software, there is no IT. In this power panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, Dave McCarthy, Director of Products at Bsquare Corporation; Alan Williamson, Principal...
Video experiences should be unique and exciting! But that doesn’t mean you need to patch all the pieces yourself. Users demand rich and engaging experiences and new ways to connect with you. But creating robust video applications at scale can be complicated, time-consuming and expensive. In his session at @ThingsExpo, Zohar Babin, Vice President of Platform, Ecosystem and Community at Kaltura, discussed how VPaaS enables you to move fast, creating scalable video experiences that reach your aud...

President Obama recently announced the launch of a new national awareness campaign to "encourage more Americans to move beyond passwords – adding an extra layer of security like a fingerprint or codes sent to your cellphone." The shift from single passwords to multi-factor authentication couldn’t be timelier or more strategic. This session will focus on why passwords alone are no longer effective, and why the time to act is now. In his session at 19th Cloud Expo, Chris Webber, security strateg...
Amazon has gradually rolled out parts of its IoT offerings in the last year, but these are just the tip of the iceberg. In addition to optimizing their back-end AWS offerings, Amazon is laying the ground work to be a major force in IoT – especially in the connected home and office. Amazon is extending its reach by building on its dominant Cloud IoT platform, its Dash Button strategy, recently announced Replenishment Services, the Echo/Alexa voice recognition control platform, the 6-7 strategic...

Whether your IoT service is connecting cars, homes, appliances, wearable, cameras or other devices, one question hangs in the balance – how do you actually make money from this service? The ability to turn your IoT service into profit requires the ability to create a monetization strategy that is flexible, scalable and working for you in real-time. It must be a transparent, smoothly implemented strategy that all stakeholders – from customers to the board – will be able to understand and comprehe...
More and more brands have jumped on the IoT bandwagon. We have an excess of wearables – activity trackers, smartwatches, smart glasses and sneakers, and more that track seemingly endless datapoints. However, most consumers have no idea what “IoT” means. Creating more wearables that track data shouldn't be the aim of brands; delivering meaningful, tangible relevance to their users should be. We're in a period in which the IoT pendulum is still swinging. Initially, it swung toward "smart for smart...
Complete Internet of Things (IoT) embedded device security is not just about the device but involves the entire product’s identity, data and control integrity, and services traversing the cloud. A device can no longer be looked at as an island; it is a part of a system. In fact, given the cross-domain interactions enabled by IoT it could be a part of many systems. Also, depending on where the device is deployed, for example, in the office building versus a factory floor or oil field, security ha...
An IoT product’s log files speak volumes about what’s happening with your products in the field, pinpointing current and potential issues, and enabling you to predict failures and save millions of dollars in inventory. But until recently, no one knew how to listen. In his session at @ThingsExpo, Dan Gettens, Chief Research Officer at OnProcess, discussed recent research by Massachusetts Institute of Technology and OnProcess Technology, where MIT created a new, breakthrough analytics model for s...
In IT, we sometimes coin terms for things before we know exactly what they are and how they’ll be used. The resulting terms may capture a common set of aspirations and goals – as “cloud” did broadly for on-demand, self-service, and flexible computing. But such a term can also lump together diverse and even competing practices, technologies, and priorities to the point where important distinctions are glossed over and lost.
