Organic Materials as Electrodes for Li-ion Batteries

The project studied organic electrode materials for rechargeable lithium batteries. Several organic compounds were synthesized, characterized and tested in battery configurations. The details are given for each class of materials. Various macrocycles, their synthesis, characterization and subsequent use in lithium-ion batteries were attempted. Ellagic acid, alizarin and phthalocycnines are relatively novel as organic electrodes in rechargeable lithium batteries, and ellagic acid and AS dye are found to be very promising, with high thermal stability. Use of these materials with magnesium- and zinc-based batteries is expected to be promising and further study is underway. Density functional theory DFT calculations are also being carried out to understand the structure-property relationship.
