To recap, organic materials, which have become a significant subject nowadays, share differences from inorganic materials. However, there are still some limits to the most organic electrode materials. The main purpose of our study is to ameliorate the cyclability, charging rate, stability, electronic conductivity, and safety of the electrode material. By mingling Copper chloride dehydrate, Gallic acid monohydrate, and polyethyleneimine, PGC is successfully discovered. The amorphous structures of PGC manifest that it has also improved the process of intercalated extraction of lithium-ions. Besides, the results of electrochemical tests proved that it has reached our targets, including high efficiency of charge and discharge and outstanding capacities and evermore. Thus, PGC is said to be a great advance in organic electrode material, and it has improved a great amount of the known limit.
