The graphene-based resistance temperature sensors application

Descrizione del progetto

Nuovo sensore di grafene per trasformare l’industria dei veicoli elettrici

Molte industrie in rapida crescita, come quella aerospaziale, automobilistica, energetica, petrolifera e del gas richiedono una misurazione di temperatura a risposta rapida, leggera, flessibile, stabile e su grandi dimensioni. L’industria delle batterie sta attualmente vivendo una rinascita e una rapida crescita della domanda nel mercato dei veicoli elettrici e dello stoccaggio della batteria di griglia. Il progetto DANUBIAGRAPH, finanziato dall’UE, ha sviluppato un sensore di temperatura di grafene, che può essere applicato su qualsiasi substrato non metallico come una pellicola estremamente sottile. Il progetto ha testato il sensore di temperatura di grafene e lo ha trovato estremamente accurato durante la convalida industriale. DANUBIAGRAPH ha progettato il sensore affinché fosse flessibile per l’uso su superfici curve, il che rende la sua area di copertura praticamente illimitata, nonché economico, con un tempo di risposta rapido e una precisione eccellente.

Obiettivo

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.
