The burgeoning energy demands of an increasingly eco-conscious population have spurred the need for sustainable energy storage devices, and have called into question the viability of the popular lithium ion battery. Dimers and tetramers of lawsone, a widely renown dye molecule extracted from the henna leaf, can provide up to four carbonyl/hydroxyl binding sites for lithium coordination that yield excellent charge storage capabilities. The oligmerization and subsequence lithium coordination of lawsone is performed via facile one-step green synthesis methods. We therefore report these lithium coordinated lawsone derivatives as candidates to advance non-toxic and recyclable green battery materials. Lawsone-based electrodes displayed a specific capacities which are favorably comparable to, or exceeding, modern Li-ion battery cathodes.
