Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
Notably, the optimization approaches are prioritized differently depending on the specific system. The particle packing electrode model provides theoretical insights for optimizing the microstructure of lithium-ion batteries to enhance their performance.
Owing to the popularity of the cylindrical cell geometry, cylindrical cell packaging material is the most commonly available packaging for lithium-ion batteries today. With the advent of portable consumer electronics, use of the prismatic cell design has grown considerably over the course of the last decade.
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.
