Abstract

Herein, the coordination-induced increase in the electron density of fused C₆ rings in MOFs as high performance anode materials for Li⁺ ion batteries is described. Zn-PTCA is able to deliver a high specific capacity of 700 mA h g⁻¹ at 50 mA g⁻¹ and exhibits excellent cycle performance over 1100 cycles and good rate capability.
