Abstract The kinetics difference of sulfur reduction reaction (SRR) results in the “shuttle effect” issue lithium–sulfur (Li–S) batteries, challenging their commercial use. electrocatalytic polysulfide conversion is regarded as a proactive strategy for suppressing such shuttling. Here, phase engineering proposed constructing high‐performance crystal catalysts, using 2D TaTe 2 typical example to demonstrate rational catalyst design principle that urgent need developing right push forward practical use Li–S batteries. Te‐enriched edges facilitate formation thin‐layer LiTe x analogs, thereby accelerating rate‐determining step SRR, evidenced by activation energy from 0.96 0.76 eV. presence dynamic catalytic intermediates (LiTe ) and mitigation shuttle effect are confirmed through situ Raman spectroscopy. Consequently, ‐catalyzed battery delivers an outstanding cycle‐ability with low capacity degradation rate 0.035% per cycle over 1500 cycles at 2.0 C, even ultrahigh retention 94.9% 100 achieved pouch cell high areal loading ≈9.4 mg cm −2 .
