Smoltek Nanotech Holding AB announced that the group company Smotek Semi has developed a new technology generation of the company's capacitor technology, CNF-MIM. The new generation, called Gen-Zero, is the foundation for achieving the goal of manufacturing different types of capacitors with very high capacitance density. High capacitance density combined with an extremely small form factor is a requirement for next-generation capacitors for advanced electronic products, such as mobile phones.

During 2023 group company Smoltek Semi has worked on developing a new technology generation of the Company's CNF-MIM capacitors with high volumetric capacitance density. Gen-Zero, as it is called, has recently been completed as part of the collaboration with YAGEO, with Smoltek Semi owning all rights to the result. With the new Gen-Zero capacitors, Smoltek can create a volumetric capacitance density of up to 120 nanofarads per square millimeter and per 1 micrometer of carbon nanofiber.

This is comparable to the best capacitors on the market. The capacitance values in the Gen-Zero capacitors are, however, lower than the competitors. This is due to the fact that Smoltek Semi has not yet optimized the length of the fibers.

The carbon nanofibers in Gen-Zero are only a few of micrometers tall. In the next generation, Gen-One, the ambition is to grow longer carbon nanofibers, up to 10 micrometers tall, which is expected to bring the capacitance values on par with the competitors.
