Abstract

Getting a charge out of lithium: The naphthalene derivative NTCDA is used to demonstrate a novel lithium ion insertion model in which each ring carbon atom can reversibly accept a lithium ion, giving discharge capacities of up to nearly 2000 mA h g−1. This method provides a new strategy for the design of high-performance organic electrodes.
