Capacity Fade
Capacity Fade is a common term in the battery industry that describes how batteries lose their ability to hold a full charge over time and use. Think of it like a phone battery that used to last all day when new but now only lasts a few hours. Battery engineers and researchers work on solving this problem to make batteries last longer. This concept is crucial in electric vehicles, consumer electronics, and energy storage systems. When reviewing resumes, you might see this term used by candidates who work on improving battery life or testing battery performance.
