The cathode is the positive electrode of a battery and the component that most defines its performance, setting the cell voltage, supplying most of the energy density, and typically accounting for the largest share of cell cost. In a lithium-ion battery the choice of cathode chemistry decides whether a cell prioritizes range, safety, power, or price. This guide explains what cathode materials are, the properties that make a good one, the main chemistries used in 2026, and the applications each o …
