“…However, unlike the reported organic electrodes with the active lithium-reacted CO/CN/CC units, most of the functional groups (CC or CN) in the MOCP structure are inactive for lithium storage, which is probably ascribed to its orderly stacking structure of MOCP without sufficient exposed surface and/or the coordination involvements of these groups. It results in the unsatisfactory electrochemical performance of MOCP electrodes for lithium-ion batteries, especially with low reversible capacities. − For example, the metal–organic hybrid compounds based on terephthalic acid (BDC) ligand has been widely explored and reported for Li-ion battery electrode materials; − however, it is not optimistic that fewer exposed active sites and inactive metal centers result in a lower specific capacity for the M-BDC-MOF (M = Co, Fe, Ni et al . ). − More efforts should be devoted to the exploration of the new structures and architectural design of MOCPs with more exposed surfaces and boosted active lithium-storage functional groups, in order to maximize the electrochemical properties of the MOCP structures and extend their practical application for energy-storage.…”

Exploration of the structures and architectural design of crystalline porous metal−organic coordination polymer (MOCP) materials with boosted active lithium-storage functional groups is still an urgent requirement for MOCP structures with improved lithium-storage properties when applied as the electrodes for next-generation lithium-ion batteries. Herein, we synthesize a carbonyl functional group modified Co-based metal−organic coordination polymer (Co-BDBA-MOCP) via a one-step facile microwave-assisted solvothermal method and apply it as the electrode material for a lithium-ion battery for the first time. The unique petals-assembled rose-shaped morphology endows the Co-BDBA-MOCP structure with a more exposed surface and porous structure, which can provide more active sites and facilitate fast Liion transport. Thus, the boosted lithium-reaction activation of the Co 2+ centers, the CC groups of the benzene rings, and the modified CO groups in the structure and further the extremely enhanced electrochemical performance can be achieved for the Co-BDBA-MOCP electrode. This electrode delivers an initial reversible capacity of 1401 mAh g −1 at a current density of 100 mA g −1 with ∼1150 mAh g −1 retained after 100 cycles, and a large reversible capacity of 743 mAh g −1 after 350 cycles at a large current of 500 mA g −1 . The exploration of the active lithium reaction units modified metal−organic frameworks with more activated functional groups for lithium storage would further shed light on high-performance electrodes for next-generation rechargeable batteries.

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.

Coordination polymers (CPs) have powerful competence as anode materials for lithium-ion batteries (LIBs) owing to their structural diversity, tunable functionality, and facile and mild synthetic conditions. Here, we show that two isostructural one-dimensional croconate-based CPs, namely, [M(CO)(HO)] (M = Mn for 1 and Co for 2; CO = croconate dianion), can work as high-performance electrode materials for rechargeable LIBs. By means of the coordination between the redox-active transition metal ion and the ligand, the anode materials were stable in the electrolyte and showed high capacities, impressive rate capabilities, and excellent cycling performance during the discharging/charging processes. The chain-based supramolecular structures of the CPs also make them stand out from a crowd of porous three-dimensional molecular materials due to their free channels between the chains for lithium ion diffusion. When tested in a voltage window of 0.01-2.4 V at 100 mA g, CPs 1 and 2 demonstrated high discharge specific capacities of 729 and 741 mA h g, respectively. The synergistical redox reactions on both metal centers and the organic moieties play a crucial role in the high electrochemical performance of CPs 1 and 2. After undergoing elevated discharging/charging rates to 2 A g, the electrodes could finally recover their capabilities as those in the initial stage when the current rate was back to 100 mA g, indicating excellent rate performance and outstanding cycling stabilities of the materials.
