Characterize and develop optimal electrode materials. The anode is the negative electrode in a battery.
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
The anode is the negative electrode in a battery. In the vast majority of batteries, graphite is used as the main material in the anode, due to it's ability to reversibly place lithium ions between its many layers. While fully charged, the graphite is ‘lithiated’ with Li+ ions being positioned between the graphite sheets.
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).
Innovative analytical solutions are required to test individual battery components, like positive and negative electrode materials, separator, electrolytes, and more, during the development and quality control in production.
