The development of high capacity batteries is necessary to increase the viability of renewable energy sources by providing efficient storage of excess energy. Therefore, currently the lithium ion batteries, with high charge storage capacity, are being further developed. In a lithium ion battery a reversible lithiated graphite is used rather than solid lithium as an anode. Research into high charge-storage capacity cells focuses on the cathode. Experimental investigations into high charge-storage capacity cathode active materials have indicated that copper phthalocyanine is one such material. Previous work involving copper phthalocyanine or other metal phthalocyanines has indicated that solid phase mass transport has a limiting effect on the lithium intercalation process, which is key to the operation of lithium ion batteries. Some models have been developed to describe the observed cell behavior, but the system is not yet fully understood. To ensure that the model formulation will best describe observable data, a literature search into lithium intercalation was conducted. A summary of the available understanding of this process and how we can apply this knowledge to the development of a lithium-ion battery with copper phthalocyanine as cathode active material is presented.
