The graphene-based resistance temperature sensors application

Description du projet

Un nouveau capteur en graphène pour transformer l’industrie des VE

De nombreuses industries à croissance rapide telles que l’aérospatiale, l’automobile, la production d’énergie, le pétrole et le gaz ont besoin d’une réponse rapide, légère, flexible, stable et capable de couvrir une grande surface pour mesurer la température. L’industrie des batteries est actuellement confrontée à une renaissance et à une demande explosive sur le marché des véhicules électriques (VE) et du stockage sur batteries sur le réseau. Le projet DANUBIAGRAPH, financé par l’UE, a élaboré un capteur de température en graphène, qui peut être appliqué sur n’importe quel substrat non métallique sous la forme d’un film extrêmement mince. Le projet a testé le capteur de température en graphène et a constaté qu’il était extrêmement précis lors de la phase de validation industrielle. DANUBIAGRAPH a conçu le capteur pour qu’il soit flexible et utilisable sur des surfaces courbes, ce qui rend l’étendue de sa zone de couverture quasiment illimitée. Ils ont également conçu le capteur afin qu’il soit bon marché et offre un temps de réponse rapide ainsi qu’une excellente précision.

Objectif

Many fast-growing industries, such as aerospace, automotive, power generation, oil & gas require fast-response, light-weight, flexible, stable, large-area temperature measurement. These requirements are particularly relevant for the battery industry which faces renaissance and booming demand both, in electric vehicle (EV) market and grid battery storage. Managing of an even distribution of temperature is key to operating of EV batteries close to their performance limits. The detailed monitoring of the battery temperature can bring great benefits and prevent potential negative effects of overheating which implicitly improves the state of health, i.e. a lifetime of batteries as well as prevents their technical failures.
Danubia NanoTech developed an effective solution - graphene temperature sensor which can be, in the form of extremely thin film, applied on any non-metallic substrate (e.g. foil, glass). The sensor confirmed the high accuracy in the industrial validation; it is very thin, ultra-light, and while produced by spray-coating, it is also very variable for application on flexible (curved) surfaces and practically unlimited in terms of coverage area. On self-adhesive film, the sensor's application is very easy, with lower material costs, with fast response and excellent accuracy. All these properties of our graphene sensor provide a great value proposition particularly for EV batteries and also for grid battery storage.
