High performance Li-, Na-, and K-ion storage in electrically conducting coordination polymers.

ABSTRACT: Coordination polymers (CPs) made of redox-active organic moieties and metal ions emerge as an important class of electroactive materials for battery applications. However, the design and synthesis of high voltage alkali-cation reservoir anionic CPs remains challenging, hindering their practical applications. Herein, we report a family of electrically conducting alkali-cation reservoir CPs with the general formula of A₂-TM-PTtSA (wherein A = Li⁺, Na⁺, or K⁺; TM = Fe²⁺, Co²⁺, or Mn²⁺; and PTtSA = benzene-1,2,4,5-tetra-methylsulfonamide). The incorporation of transition metal centers not only enables intrinsic high electrical conductivity, but also shows an impressive redox potential increase of as high as 1 V as com
