About the Project

Development of all-solid-state batteries made by 3D printing

Next-generation lithium-ion batteries will need to offer higher energy and power densities at a lower cost. Current battery manufacturing is struggling to further improve these key metrics. The EU-funded AM4BAT project will leverage additive manufacturing technologies for fabricating 3D lithium-ion batteries.

Using vat photopolymerisation 3D printing, the aim is to develop a high-performance battery with energy density of 400 Wh/kg for electric vehicles. AM4BAT outcomes will contribute to the creation of a sustainable European battery manufacturing value chain, helping the EU to succeed in the electric mobility rollout.

The overall objective of AM4BAT is to develop an anode-free solid-state battery (SSB), fabricated by Vat Photopolymerization 3D printing by LCD reaching energy density of 400 Wh/kg and 1000 Wh/L for Electric vehicles (EV) applications.

The assembly and validation of a 3-Ah cell is aimed with a charge capability of 70% of its total capacity in 5 minutes and cyclability of 3.000 cycles reaching 80% of the initial beginning of load.
