Ultimately, the development of electrode materials is a system engineering, depending on not only material properties but also the operating conditions and the compatibility with other battery components, including electrolytes, binders, and conductive additives. The breakthroughs of electrode materials are on the way for next-generation batteries.
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).
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
Modern organic electrode materials will potentially enable the latest battery chemistries for meeting the cost, safety, and specific energy requirements of electric vehicles and grid storage.
Several new electrode materials have been invented over the past 20 years, but there is, as yet, no ideal system that allows battery manufacturers to achieve all of the requirements for vehicular applications.
