AM4BAT project founded by the European Commission under the Horizon Europe programme (grant agreement No 101069756). with a total budget of €4,8M. The 4-year project is coordinated by the Technological Center Leitat and is integrated by 11 partners from 7 different countries. AM4BAT main objective is to develop an anode-free all-solid-state batteries made by 3D Printing.

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. The rapid rise of electric mobility and renewable energies is pushing the market for Li-ion batteries to next levels. By 2030, global battery demand is expected to have grown 19-fold versus 2018 volumes. Commercial Li-ion reaches their limits with gravimetric and volumetric energy densities of 300 Wh/kg and 700 Wh/L.
