abstract = {The growth of Na-dendrites and the dissolution of organic
cathodes are twomajor challenges that hinder the development
of sodium-organic batteries(SOBs). Herein, a multifunctional
Janus separator (h-BN@PP@C) by using aninterfacial
engineering strategy, is proposed to tackle the issues of
SOBs. Thecarbon layer facing the organic cathode serves as a
barrier to capturedissolved organic materials and enhance
their utilization. Meanwhile, theh-BN layer facing the Na
anode possesses high thermal conductivity andmechanical
strength, which mitigates the occurrence of
localized-temperature“hot spots” and promotes the
formation of a NaF-enriched SEI, therebysuppressing dendrite
growth. Consequently, the Janus separator enables astable Na
plating/stripping cycling for 1000 h at 3 mA cm−2.
Equipped withthe Janus separator, organic cathodes including
dibenzo[b,i]thianthrene-5,7,12,14-tetraone (DTT),
pentacene-5,7,12,14-tetrone andCalix[4]quinone cathodes
demonstrate high capacity and remarkable cyclingperformance.
In particular, the DTT exhibits a bipolar co-reaction
storagemechanism and achieves an ultrahigh capacity
(≈342.6 mAh g−1), long-termcycling stability (capacity
decay rate of $0.15\%$ per cycle over 550 cycles at500 mA
g−1) and fast kinetics (1000 mA g−1≈2.8 C). This study
offers astraightforward, effective, and promising solution
to address the challenges in SOBs.},
