Perylene-polyimide-Based Organic Electrode Materials\nfor Rechargeable Lithium Batteries

Abstract

Organic materials for Li-ion battery\napplication continue gaining\nattention due the virtue of low cost, environmental benignity, and\nso on. A new class of electroactive organic material called polyimides\nis particularly important due to the extra stability exhibited at\nhigher current rates. High-performance rechargeable lithium battery\ncathodes based on polyimides of 3,4,9,10-perylenetetracarboxylicacid-dianhydride\nare prepared. The novel electrodes exhibit good rate capability and\nimproved cycling stability, which result from their combined beneficial\nproperties such as the presence of additional carbonyl groups, favorable\nband gap, and enhanced conductivity, making it a potential material\nfor greener and sustainable electrochemical storage devices.
