Abstract The spin state of transition‐metal compounds in lithium‐sulfur batteries (LSBs) significantly impacts the electronic properties and kinetics sulfur redox reactions (SRR). However, accurately designing remains challenging, which is crucial for understanding structure‐performance relationship developing high‐performance electrocatalysts. Herein, CoF 2 , specifically Co 2+ with 3 d 7 electrons a high‐spin distribution (t 2g 5 e g ), were tailored predictably first time through weak coordination field effect F element. Both DFT calculations experimental results confirm that transitions from low‐ to configurations strongly interacts species Co−S Li−F bonds during SRR process. This interaction weakens S−S bond, promoting its facile cleavage both ends while also facilitating rapid uniform nucleation Li S /Li S, thus resulting LSBs capacity 447.7 mAh −1 at 10 C rates stable cycling 1000 cycles, an acceptable practical 585 high loading mass mg cm −2 . work achieves rational control active electron enriches application accelerate LSBs.
