Optimization

Definition

Optimization refers to the process of making a system as effective or functional as possible, often by maximizing desired outcomes while minimizing resource use or costs. In the context of cathode materials, optimization involves refining the structure, properties, and performance of these materials to enhance their efficiency in energy storage applications, such as lithium-ion batteries. Achieving optimal performance is crucial for ensuring that cathodes provide high energy density, good conductivity, and long cycle life.
