Abstract

At present inorganic electrodes are present in the lithium batteries which are used in a wide range of applications. Because of the demand it is mandatory to develop environmentally friendly electrode for the batteries. In order to develop sustainable and eco-friendly batteries we can use purpurin which is an organic compound obtained from the plant madder. Purpurin contain hydroxyl groups, which act as redox centres and reacts electrochemically with Li-ions during the charge/discharge process. The mechanism of lithiation of purpurin is fully elucidated using NMR, UV and FTIR spectral studies. The six membered binding core of lithium is formed with hydroxyl groups of purpurin at C-1 and C-4 positions which facilitates lithiation process, where Hydroxyl groups at C-2 remains unaltered.
