Introducing the World's First Subway Seats Enhanced with BGI's Graphene-Based Material

In a groundbreaking advancement, the Beijing Graphene Institute (BGI) has successfully integrated its state-of-the-art Super Graphene Skinned Material into the subway seat heating units manufactured by CRRC Changke Erqi Railway Equipments Co., Ltd. This achievement marks the debut of the world’s first subway utilizing this innovative material for electrically heated seats, showcasing its first significant application in the realm of public transportation heating solutions.

The advent of this technology brings a new level of warmth and comfort to winter commutes, particularly vital in colder regions where the frequent opening of subway doors can lead to rapid decreases in cabin temperature, affecting passenger comfort. Traditional heated seats, often reliant on carbon fiber elements, face challenges like uneven heating and potential long-term durability issues. BGI’s solution revolutionizes this with its Super Graphene Skinned heating film, a pure carbon atom film developed through Chemical Vapor Deposition (CVD), embodying flexibility and uniform heating capabilities.BGI’s proprietary Super Graphene Skinned Material is engineered through a sophisticated process of high-temperature pyrolysis and growth, applying CVD to create a continuous graphene film over traditional substrates. This material emerges as a frontrunner in the Super Graphene Skinned family, making its debut in the civilian market with its exceptional conductive, thermal, and infrared properties, positioning it as the preferred choice for advanced heating solutions.

The subway seats enhanced with BGI’s Super Graphene Skinned solution offer optimal warmth, reaching surface temperatures up to 40°C, and leverage graphene’s rapid heating and even heat distribution. Its high porosity and three-dimensional weave ensure superior compatibility with existing subway seat materials, facilitating seamless integration and superior performance.

Extensive durability tests confirm that the Super Graphene Skinned Material maintains consistent performance without power degradation over time, surpassing traditional carbon fiber heating solutions in both process compatibility and heat uniformity. This successful rollout signifies a landmark moment, transitioning graphene from a high-tech wonder to a practical application in everyday public transit, promising to broaden the spectrum of graphene’s applications in the consumer market while redefining passenger comfort in urban mobility.
