A novel in situ co‐assembled nanocomposite LSM‐Bi 1.6 Er 0.4 O 3 (ESB) (icn‐LSMESB) was obtained by conjugated wet‐chemical synthesis. It showed an enhancement of the cathode polarization at 600 °C by >140 times relative to conventional LSM‐Y 0.08 Zr 0.84 O 1.92 (YSZ) cathodes and exceptional solid oxide fuel cell (SOFC) performance of >2 W cm −2 below 750 °C. This demonstrates that this novel cost‐effective and broadly applicable process provides new opportunities for performance enhancement of energy storage and conversion devices by nanotailoring of composite electrodes.
