Organic electrodes hold great promise for sustainable electrodes in sodium‐ion batteries (SIBs) owing to their easy availability from biomass. However, traditional organic electrodes suffer from two inherent problems, high solubility in organic electrolytes and low electronic conductivity. Here, a calcium organic salt, Cabpdc (bpdc=4,4′‐biphenyldicarboxylate) was designed and formed into a composite with reduced graphene oxide (rGO) to improve these two problems by a “two‐in‐one” approach. As expected, the Cabpdc/rGO composite displayed competitive cycle and rate performances as an anode for SIBs. Additionally, all‐organic sodium‐ion full cells were successfully fabricated combining this anode with a commercial organic cathode, promising applications for sustainable SIBs.
