The Next Stage in Thermal Materials for 5G

Whilst much of the "5G" infrastructure is a moderate upgrade on existing 4G technology, there is still plenty of scope for higher frequency deployment such as mmWave devices and very different station types such as small cells. Each of these new developments presents its own technological evolution and with it, thermal challenges.

Automotive Autonomy: A New Opportunity for Thermal Materials

IDTechEx's new report, "Thermal Management for ADAS: 2023-2033" finds that the yearly market value for thermal interface materials (TIMs) in ADAS will increase 11-fold over the next 10 years.

5G: The Market GaN Needs

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.

La bataille des matériaux de la 5G : Sub-6 GHz vs. ondes millimétriques

Le déploiement de la 5G bat son plein, les infrastructures de bande moyenne installées d'ici fin 2021 représentant près de 6 fois ce qu'elles étaient en 2019. Cependant, cela ne signifie pas que tous les défis ont été résolus. Une grande partie de l'infrastructure 5G est constituée d'équipements 4G reconvertis dans des bandes de fréquences inférieures. La véritable transition vers la 5G vient de l'adoption de fréquences plus élevées qui ont été largement catégorisées en bandes sub-6 GHz et mmWave (> 20 GHz). L'un des principaux défis à relever est la gestion thermique.

Being a Motor Manufacturer in a Materials Crisis

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 Fires: Less Common But More Problematic?

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?

EV Material and Component Opportunities Outside the Battery Cell

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?

La gestion thermique dans la révolution du carbure de silicium, discutée par IDTechEx

Pour les véhicules électriques (VE), l'efficacité est le mot d'ordre. Il existe de nombreuses façons d'améliorer l'efficacité, notamment au sein du groupe propulsion, l'un des domaines clés étant l'électronique de puissance. Parmi ces composants, l'onduleur principal est le plus puissant et offre les meilleures possibilités pour améliorer l'efficacité. L'onduleur principal est chargé de convertir la sortie CC de la batterie en entrée CA pour le moteur électrique. Ces dernières années, nous avons commencé à voir des semi-conducteurs à large bande tels que le carbure de silicium (SiC) adoptés dans les onduleurs des VE pour remplacer les transistors bipolaires à grille isolée en silicium (Si IGBT).

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.

Key Trends That Are Turning Up The Heat In The EV Market

Within the EV market, increases are being seen in battery capacity, range, charging rates, wide bandgap semiconductors, and high-performance traction motors. Additionally, EV fires and related recalls have brought the concept of thermal runaway detection, prevention, and protection to the fore. All of these trends demand more effective thermal management systems, solutions, and materials.
