Thermal Management

Adding a new spectrum is key to each new generation of telecommunications. The two new frequency bands in 5G are sub-6 GHz (3.5 - 7 GHz) and mmWave (24 - 71 GHz).

The field of nanocarbons is not new and it has certainly been the victim of too much hype and false dawns, but things have changed. Across 2022 and into the decade ahead, CNTs and graphene will enter different phases of their industrial expansion.

The occurrence of fires in electric vehicles (EVs) is less common than their combustion engine counterparts, in total number but also in terms of the rate per miles traveled. However infrequent, it is extremely important to protect the vehicle's occupants and prolong the time for a fire to exit the battery pack for as long as possible.

Where does 5G stand three years after its first commercialization in 2019? Let's start with the frequency band. We know that the sub-6 GHz (3.5 - 7 GHz) and millimeter wave (mmWave, >24 GHz) bands are the two new bands among the spectrum covered in 5G. Despite the hype surrounding mmWave, according to IDTechEx's "5G Market 2023-2033: Technology, Trends, Forecasts, Players" report, 53% of 5G commercial/pre-commercial services are actually based on sub-6 GHz, with mmWave accounting only for less than 10% of the market.

In this article, IDTechEx will cover the growth drivers of advanced semiconductor packaging technologies on data center applications, as well as give several examples of cutting-edge commercial server products that adopt advanced semiconductor packaging technologies. The content of this article is from IDTechEx's newly released market research report, "Advanced semiconductor packaging 2022-2033".

As of mid-2022, the global graphene and graphene oxide installed capacity easily exceeds 12,000 tonnes per year, but utilization is low as the orders lag significantly behind. Is this a natural part of the commercial journey, or has hype overcome reality? Is this a case of "build it, they will come", or are there real market needs? What does the future hold for these graphene manufacturers? IDTechEx provides an independent perspective on these questions and more.

The past decade has seen an ever-increasing number of companies within the graphene market, with a seemingly constant stream of new material suppliers appearing. As is the case for any well-established industry, market stability and profitability are expected to go hand in hand with the emergence of a handful of dominant players within the material supply chain.

The current iteration of Li-ion batteries, which are based on graphite anodes, liquid electrolytes, and cathode materials such as NMC and LFP, are generally considered to be reaching their performance limits. However, from cell materials to battery designs, there are still several routes that can lead to further improvements in performance and cost.

To date, the commercialization of graphene has been more of a "material push" rather than a "market pull"; a solution looking for a problem. In this first phase, there were numerous technical and commercial barriers to overcome, which in materials science does not happen overnight. IDTechEx believes that this is changing, with graphene entering the next stage, the growth phase, of its commercial journey.
