abstract = {Solid-state lithium batteries (SSLBs) are considered to be
one of the most promising next-generation Li batteries due
to their high capacity and intrinsic safety. However, their
sustainable processing is often poorly investigated but
could offer additional advantages over conventional
batteries in terms of ecological and economic benefits. In
this work, a sustainable, water-based processing route for
garnet-supported SSLBs featuring a LiFePO4
(LFP)-poly(ethylene oxide) (PEO) composite cathode is
presented. Both the LFP-PEO cathode and the thin
free-standing garnet separator (105 μm) are fabricated by
water-based tape-casting. After optimizing the composition
of the cathode, the full cell with a thin cathode (∼45
μm) delivers a high capacity of 136 mAh g–1 with a high
Coulombic efficiency over $99\%$ and good cycling stability
for 50 cycles. However, the performance and cycling
stability decrease when thicker cathodes (∼110 μm) and
higher rates were applied, indicating the need for further
optimization. Nevertheless, the here-presented water-based
fabrication route provides a baseline for further
improvements and pushes SSLB fabrication further toward a
green battery production.},
