Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

The EXTENDED project is motivated by the urgent global demand for innovative energy storage solutions to facilitate the transition towards decarbonization and electrification. To improve the renewable energies transition and to transform mobility as it knows at the moment, current battery technologies fall short in meeting the necessary standards for energy density, safety, cost-effectiveness, and environmental sustainability. To tackle these issues, EXTENDED is focused on the development of semi-solid-state batteries that deliver superior performance, enhanced safety, and a lower environmental impact.

This project adopts a comprehensive strategy, involving the design and creation of modular battery systems that can be tailored to various applications. It employs advanced computer modeling and simulations to optimize battery configurations for specific uses, including electric vehicles and stationary energy storage. To streamline battery management systems, EXTENDED integrates wireless technology and printed sensors, thereby reducing complexity and enhancing adaptability. Additionally, the project prioritizes the development of lightweight and safe battery components utilizing polymer-based materials, which increases energy density and improves thermal stability.

A crucial element of EXTENDED is the creation of an advanced thermal management solution aimed at maximizing battery performance and longevity. This includes thorough testing and validation of battery prototypes under realistic conditions to ensure operational reliability across multiple applications. The project is dedicated to minimizing its environmental footprint by examining the entire battery life cycle, optimizing designs for efficient manufacturing and recyclability, and investigating second-life applications.

EXTENDED seeks to establish decarbonization strategies by encouraging the use of these advanced batteries across various transportation and mobile applications. This involves creating a roadmap with measurable objectives and actively collaborating with stakeholders in the transportation sector.

By merging these technological innovations with a focus on societal impact, EXTENDED aims to develop a sustainable and efficient energy storage solution that contributes to a cleaner and more electrified future.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

By M18, EXTENDED achieved significant progress across several key areas.

In modular battery system design, a conceptual design for a scalable system adaptable for EV, EV-BUS, and stationary storage applications is under development. This design prioritizes efficient assembly/disassembly, lightweight materials, and overall safety, with ongoing optimization for material and energy efficiency throughout the battery life cycle. Key technical requirements for pressure control, thermal management, and system integration have been identified.
Regarding electrical solutions, novel Battery Management System (BMS) architectures are being evaluated to ensure high performance and safety, considering constraints related to novel cell chemistries. Simultaneously, advanced sensing solutions, including printed sensors with near-field communication, are being developed to enhance safety and reliability.
For thermal solutions, extensive testing has characterized the thermal behavior of individual semi-solid-state cells. This data informs the design of a scalable thermal management system with an emphasis on efficient heating management. Battery module behavior under extreme conditions has been evaluated, and mitigation solutions for potential risks have been proposed.
Concerning mechanical solutions, cost-efficient manufacturing solutions for semi-solid-state battery pack enclosures are being developed, addressing requirements for enhanced mechanical resistance and durability. Novel cell holders with adaptive pressure control are being designed to ensure optimal performance and safety. Functional integration of components into larger assemblies is being evaluated for increased efficiency and cost reduction.
Finally, safety assessment remains a core focus. Extensive abuse tests are being conducted to investigate the safety performance of semi-solid-state cells. Virtual safety performance evaluations of the entire battery system concept across different applications are planned.

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

Within its first 18 months, EXTENDED has achieved significant results, exceeding the current state-of-the-art. The consortium established use case requirements and definitions, with a focus on safety and security, guiding the development of technologies to meet KPIs for electric vehicles, buses, and stationary applications. These insights informed the development of specifications for the simulation platform, architectural design guidelines, and benchmarking of existing solutions.
EXTENDED generated conceptual designs for all major systems, including mechanical, thermal, and electrical components, utilizing a holistic approach to battery pack design. This approach prioritizes material and energy efficiency throughout the entire life cycle, optimizing production, enhancing durability and recyclability, and minimizing environmental impact. The project defined the battery management system, safety requirements, architecture, and a conceptual design for the mechanical solution.
Looking forward, EXTENDED has an ambitious plan to achieve higher technology readiness levels (TRLs), guided by analyses of key expected results (KERs). This roadmap will drive manufacturing technology development and address market needs.
To ensure continued success, EXTENDED requires further research and development, including demonstration projects to showcase capabilities and build confidence among potential users. Facilitating market access, securing funding, and implementing a robust commercialization strategy are vital for successful technology transfer. Protecting intellectual property, fostering international collaboration, and establishing a supportive regulatory framework are equally important for translating EXTENDED's research into impactful contributions to the field of sustainable and efficient battery technologies.
