All Solid-s Tate Reliable BATtery for 2025



Europe is facing a major challenge to develop and produce a competitive Li-battery product in order to avoid dependency on third countries in its energy transition models. The Li-ion cell innovations should meet specific technical and economical requirements to sustain the market growth. The all-solid Li-ion technology appears to be one of the relevant options but it still has to be brought to higher TRL to be economically and environmentally friendly for a mass production compatible process. The ASTRABAT project gathers 14 partners, leaders in the different fields of research, development and production, from 8 countries. It aims to find optimal solid-state cell materials, components and architecture that are well suited to the demands of the electric vehicle market and compatible with mass production. The project will comply with improved safety demands and industrial standards. Five ambitious objectives were defined:

  1. Development of materials for a solid hybrid electrolyte and electrodes enabling high energy, high voltage and reliable all-solid-state Li-ion cells.

  2. Gen#2D cell design: processing techniques compatible with existing routes of large scale cell manufacturing (10Ah, Energy type) and validation of a pilot prototype in a relevant industrial environment.

  3. Development of a 2030s eco-designed generation for Power-type and Energy type all-solid-state cells in pre-prototype (Gen#3DS and #3DC).

  4. Define an efficient cell architecture to comply with improved safety demands.

  5. Structuration of the whole value chain of the all-solid-state battery, including eco-design, end of life and recycling.

The project will reinforce the European battery value chain, strengthen collaborations between RTOs, SMEs and Industrial partners from material development to integration in vehicles. The implementation of related work packages, tasks, milestones and risk assessment is considered to achieve these objectives comprehensively.
