A heterobimetallic single-source precursor, NaCo(acac)3, featuring a 1D chain structure was for the first time designed to achieve layered oxide P2-NaxCoO2 with superior rate capability for Na-ion batteries (SIBs). It opens a new avenue to synthesize high-performance layered oxide cathode materials for SIBs.
