Reformation of organic dicarboxylate electrode materials for rechargeable batteries by molecular self-assembly

Abstract

We have found that the specific capacity of a Li-intercalated metal–organic framework (iMOF) electrode material, 2,6-naphthalene dicarboxylate dilithium, can be increased by narrowing the distance between naphthalene layers via ordering. The increase in specific capacity can be attributed to formation of more efficient electron and ion pathways in the framework.
