Descripción del proyecto
Baterías estructurales avanzadas para la próxima generación de aeronaves eléctricas híbridas
El proyecto SOLIFLY, financiado con fondos europeos, responderá a la petición europea de soluciones de almacenamiento eléctrico de alta densidad de potencia o multifuncional para aplicaciones aeronáuticas trabajando en un concepto innovador de batería. Más concretamente, las nuevas baterías contarán con materiales multifuncionales con un grado de integración alto (fibras de carbono recubiertas) y elementos multifuncionales con un grado de integración medio (pilas multicapa reforzadas). El objetivo de SOLIFLY es entregar el primer panel aeronáutico rígido con una batería integrada de iones de litio de estado semisólido. El trabajo del proyecto allanará el camino para conseguir que las baterías estructurales sean una tecnología viable para la próxima generación de aeronaves eléctricas de pasajeros.
Objetivo
SOLIFLY responds in full to the challenges of the JTI-CS2-2020-CfP11-THT-11 call, “High Power density / multifunctional electrical storage solutions for aeronautic applications”, by developing and combining two structural battery concepts: (i) multi-functional materials with a high degree of integration - Coated Carbon Fibres (CCF), and (ii) multi-functional elements with a medium degree of integration - Reinforced Multilayer Stack (RMS).
The project has three vertical objectives:
• exploring and advancing a non-conventional semi-solid-state Li-ion battery material formulation suit-able for structural batteries: NMC622 (cathode), Si/C (anode) and bicontinuous polymer-ionic liquid electrolyte (BCE), i.e. NMC622|BCE|Si/C;
• enabling the functional integration of this material within the CCF and RMS concepts, upscaling them to the level of a representative aeronautic stiffened panel structure, i.e. SOLIFLY demonstrator;
• characterising the electrochemical and mechanical performance of this demonstrator.
These vertical objectives are complemented with a horizontal one: to tailor SOLIFLY to the needs of the aeronautic industry. This is achieved by factoring end-user requirements and specifications into the design process right from the start, and by including airworthiness and manufacturing criteria together with a technology roadmap and TRL scale-up strategy. The SOLIFLY demonstrator aims at achieving a gravimetric energy density at cell level between 100 and 180 Wh/kg, a nominal discharge rate of 1C, being capable of sustaining 300+ cycles at 0.1C with 90% capacity retention and achieving TRL 4 by the end of the project (2023).
SOLIFLY ultimately aims at supporting the long-term development of the European aeronautic industry, delivering the first aeronautic stiffened panel with an integrated semi-solid-state battery, and paving the way for making structural batteries a viable technology for the next generation hybrid electric airliner.
