In lithium-ion batteries, the positive electrode generally limits the performance of the battery, because with a lower aerial capacity compared to the negative one. Hence, we decide to use the positive electrode state of charge (SOC p) for performance evaluation.
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
Despite numerous endeavors to fine-tune their redox potential, the pool of organic positive electrode materials with a redox potential above 3 V versus Li + /Li 0, and maintaining air stability in the Li-reservoir configuration remains limited.
With the development of artificial intelligence and the intersection of machine learning (ML) and materials science, the reclamation of ML technology in the realm of lithium ion batteries (LIBs) has inspired more promising battery development approaches, especially in battery material design, performance prediction, and structural optimization.
Instead, to assess the performance of the physics-based model, only voltage response and positive electrode SOC are used. In lithium-ion batteries, the positive electrode generally limits the performance of the battery, because with a lower aerial capacity compared to the negative one.
