Track Record

Graphenest S.A. was founded in 2015 by three young Portuguese entrepreneurs with a total investment of more than EUR 1.5 M from Portugal Ventures (a Portuguese venture capital company). Graphenest’s initial endeavor was related to the design, development, and optimization of a proprietary state-of-the-art graphene production technology. Graphenest was part of the class of 2017 of the international acceleration program AdMaCom, and later the same year became an Associated Member of Europe’s biggest research initiative: The Graphene Flagship. In 2018, Graphenest was the only foreign company to be invited to participate in Techstars Autonomous Technology Accelerator (Boston, MA) with the United States Air Force, which was focusing on companies developing drone and counter-drone technology. Currently, the team is composed of 8 highly talented people with a vast scientific and industrial background in chemical, mechanical, physics, and electronics engineering, as well as an experienced technical business developer.

Value Proposition

Graphenest aims at the development and implementation of the next generation of Electromagnetic Shielding Graphene-based Solutions for the electric mobility market, helping Suppliers Tiers 1 & 2 manufacturers to:

Comply with industry regulations and standards

Europe imports large amounts of ore, as well as high amounts of refined metals, processed metal compounds, and alloys. However, Europe is flowing towards the implementation of more restricted imports of metals, guiding industry to the commitment of responsible sourcing to reduce mining pollution and enhance sustainability.

Meet OEM requirements

policymakers and regulatory bodies are implementing new goals and laws for the reduction of the industry’s carbon footprint. The European Commission proposes to cut greenhouse gas emissions by at least 55% by 2030, setting Europe on a responsible path to becoming climate neutral by 2050. Simultaneously, the European Union is proposing that all new cars sold from 2035 should have zero emissions putting a lot of pressure on the OEMs.

Decrease the cost and production times

the typically metal-based solutions are produced in energy- and time-intensive processes. For instance – Coaxial cables alternatives can be produced 50x times faster by replacing slower metal braiding processes.

Enhance shielding and weight performance

the EVs are still heavy (+30% more than their combustion counterpart) therefore possess low mileage autonomy due to the usage of heavy metal-based solutions that are transversal to all used components. In this regard, battery life expectancy remains low: the lifespan of EV batteries is of high importance, due to the power source for an electric car being an expensive component to replace. As the industry assembles more vehicles with battery packs, lifetime management of a battery is an important aspect for the OEM. With EV the shielding issues are magnified. The large magnetic field between the battery cables and the engine, as well as the battery and the charger, can negatively affect electronic systems in the vehicle. EMI originated from external sources is also a cause for concern, as it can harm the battery and all of its associated electronic circuits. This topic is of high importance in upcoming EV technologies such as 5G and 6G communications.
