Swedish participation in the M-ERA.NET initiated project GREEN-BAT

Important results from the project

The project explored advanced, scalable manufacturing routes for all-solid-state lithium-ion batteries (ASSLB), focusing on development of complex multi-layered architectures using thermal spray and laser-based techniques as manufacturing solutions. It demonstrated that the above deposition methods can be harnessed not only for fabrication of individual battery constituents but also their consolidation into an entire solid-state battery cell using sequential, single-step processes.

Expected long term effects

The project explored novel processing approaches, laying a sound foundation for further development. Single-step processing methods (APS, SPS, LPPS) for fabricating all-solid-state lithium battery components were demonstrated and multi-layer full-cell assemblies also fabricated. These prototypes validate feasibility of scalable production of ASSLBs, using industrially relevant approaches whose adoption can lead to cost reduction, increased throughput, and enhanced safety.

Approach and implementation

The project operated as a seamless alliance between three countries, with each partner contributing complementary expertise toward common objectives. Robust communication channels facilitated seamless exchange of ideas and information. Bimonthly meetings provided a structured platform for partners to share updates, address challenges, and strategize for optimal project advancement. This transparent communication ensured that each partner remained aligned with the project’s overarching goals.
