Surprises abound in the new IDTechEx Research report, "Supercapacitor Markets, Technology Roadmap, Opportunities 2021-2041"

What do you now purchase by the kilowatt hour? The new supercapacitors replacing batteries. The new IDTechEx report, "Supercapacitor Markets, Technology Roadmap, Opportunities 2021-2041", shows how supercapacitors have started to replace 10% of lithium-ion batteries and help kill lead-acid.

Supercapacitors Turn the Corner - Supercapacitors and their variants have recently seen customer commitment to multibillion-dollar opportunities that were previously beyond their reach. Consider large peak-shaving ones for hybrid cars where the Geely orders will soon be followed by others.

This article highlights some key material development trends. More specifically, approaches to increase the thermal conductivity (in W/mK) of TIMs are considered. This is an important trend because the IDTechEx assessment is that the market, in absolute terms, for high or ultrahigh thermal conductivity TIM materials, will inevitably rise.

The electric vehicle market is growing rapidly, and with it the demand for fast charging, increased energy density and improved safety. Something that all these areas have in common is heat. Charging a battery quickly generates a lot of heat, with the extra energy capacity of modern and upcoming electric vehicle batteries, extracting this heat becomes more challenging.

The EV market is booming. The battery is a key feature for both cost and performance, the chemistry and cell levels are extensively discussed. However, everything else that goes into a pack is often overlooked.

Thermal Interface Materials (TIM) are not glamourous but are often an essential component found in all manner of electronic and energy storage applications. Indeed, they are absolutely pervasive. They are truly a diverse technology in terms of suppliers, material options, deposition techniques, applications, market requirement and performance levels. This makes them difficult to analyse.

Diesel generator sets remain crucial to many key industries and are a multi-billion dollar global market.

As society and equipment become more mobile and remote from grids, diesel and gas gensets will be bought in larger numbers for a few years yet - possibly peaking at around $30 billion global market size when over 600GW will be deployed. The Zero Genset market will rise to at least $100 billion if it replaces significant grid power.

IDTechEx attended the event last week to meet with key stakeholders including industrial OEMs, power module manufacturers, established semiconductor companies and innovative new GaN (gallium nitride) and SiC (silicon carbide) developers to report back on the current and future trends. The following article is the second of two parts and provides a summary of some of the key GaN related developments and at the event and their impact on various industries and applications.
