Indeed, not a working product. Working lab-only 'hardware'. The "methods section" in the Nature paper is fascinating: "The anode-solid electrolyte-cathode for half-battery or anode-solid electrolyte-anode for symmetric battery were pressed together in a homemade pressurized cell at 467 MPa and kept at 50–250 MPa during testing." "All batteries were assembled in an argon atmosphere glovebox and the galvanostatic battery cycling test was performed on an ArbinBT2000 workstation."
