Conversion-type transition metal-based materials (MZx) are considered promising cathodes for lithium metal batteries due to their low cost, abundant availability, and high theoretical energy density. However, they suffer from rapid capacity decay caused by the transformation into two inhomogeneous phases during discharge. Herein, we use a pulse current discharge activation method (under 3C) induce homogeneous phase nucleations. As result, microsized FeS2 cathode transforms mixture of nanosized Fe Li2S, effectively mitigating volume expansion. It exhibits exceptional cycling performance, delivering specific 572.8 mAh g–1 after 800 cycles at 0.33C. Even areal 5.4 cm–2, it undergoes 180 with retention 89.3% This work highlights crucial role nucleation in achieving long life conversion-type cathodes.
