A highly conductive conjugated coordination polymer for fast-charge sodium-ion batteries: reconsidering its structures

Conjugated coordination polymers (CCPs), showing high conductivity, can be expected to be possibly applied in batteries, which, however, have not been well studied. Furthermore, CCPs are so unique that most of their chemical structures have not been well determined. Herein, a highly conductive CCP is reported for sodium-ion batteries, which shows high rate performance and high capacity retention of 84% even at 30C. What's more, the chemical structure is successfully revealed based on the structure variation during the electrochemical redox process.
