Abstract

Problems such as low cycle stability, poor ion mobility and weak conductivity hinder the development of organic electrode materials. Herein, one of the robust porous hydrogen-bonded organic frameworks (HOFs), CPHATN-1a, has been used as a cathode for lithium-ion batteries (LIBs). Redox-active hexaazatrinaphthalene (HATN) moieties were firmly fixed in this HOF by the hydrogen-bonded connection and tight π–π packing, providing a high capacity of 128 mA h g⁻¹ at 0.1C. In addition, this HOF-based LIB is able to deliver a high cycling stability with 102 mA h g⁻¹ after 500 cycles at 1.0C and a good rate capability (78 mA h g⁻¹ at 2.0C). Moreover, the Li storage mechanism associated with the HOF was systematically analysed by electrochemistry, X-ray photoelectron spectroscopy and powder X-ray diffraction. These results indicate the bright perspective of robust HOFs as organic cathode materials for LIBs.
