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.
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.
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.
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.
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.
The electrode performance of Li insertion materials such as reversibility, cyclability, rate capability, and reaction kinetics is generally evaluated by several electrochemical measurements.

A lithium-ion battery consists of a positive electrode, a negative electrode, an electrolytic solution, and a separator. When a battery is charged, lithium ions escape from the positive electrode made of metal oxide, pass through the electrolytic solution, reach the negative electrode, and accumulate. During discharge, lithium ions emitted from the
