5G: GaNに必要な市場

The current state of 5G has seen less technological innovation than might have initially been expected. There is certainly more scope for technical development and hence opportunities for several technologies and materials, a critical one of which is the semiconductor technology with wide bandgap semiconductors.

5G半導体材料の戦い:サブ6GHz帯vsミリ波

5G deployment is in full swing with mid-band infrastructure installed by the end of 2021 representing nearly 6 times what it was in 2019. However, this doesn't mean that all of the challenges have been solved. Much of the 5G infrastructure is repurposed 4G equipment at lower frequency bands. The real transition to 5G comes from the adoption of higher frequencies which have largely been categorized into sub-6 GHz and mmWave (> 20 GHz) bands. One of the key challenges is thermal management.

材料の危機的状況におけるモーターメーカーのあり方

The past two years have been extremely turbulent for many industries with production lines shutting down, chip shortages, and a host of general supply chain issues. Amongst the dismay, electric vehicles (EVs) have been a shining light. In 2021, sales of EVs globally grew by around 80% over 2020 which in turn was a growth of 44% over 2019.

EV火災:頻度は低いが問題は多い?

Fires in electric vehicles (EVs) certainly gain a lot of media attention in comparison to their internal combustion engine (ICE) counterparts. But a crucial question for the future of mobility is whether EVs are actually any more likely to catch fire than an ICE vehicle. There is always a non-zero risk of Lithium-ion batteries entering thermal runaway but the key points are how likely is a fire, how problematic is an EV fire and what is being done to prevent or limit them in the future?

バッテリーセル以外のEV材料・部品の可能性

When talking about the electric vehicle (EV) market, a great amount of emphasis is put on the battery cells - and rightly so. They govern the total storage capacity, impact energy density, and are a critical supply chain consideration when scaling up to meet the growing EV demand. However, EVs present a great range of opportunities outside of the battery cells.

Rare Earths in EVs: Problems, Solutions and What Is Actually Happening

EVs certainly mark the path to a more environmentally friendly future, but there are still concerns around the sourcing of certain components or materials within EVs. Electric motors literally drive EVs but rely heavily on rare-earth materials. Will EV manufacturers continue to rely so heavily on rare earths going into the future?

Thermal Management in the Silicon Carbide Revolution

For electric vehicles (EVs), efficiency is the name of the game. In the past few years, we have started to see wide bandgap semiconductors such as silicon carbide (SiC) adopted in EV inverters to replace the typical silicon insulated-gate bipolar transistors (Si IGBTs).

EV Fires: Disaster for Automakers, Opportunity for Material Suppliers

Whilst IDTechEx expects EVs to continually improve in safety, there will always be the risk of a battery fire due to many potential causes. This presents an opportunity for those material suppliers making thermal interface materials (TIMs), flame-retardant materials, or fire protection materials.
