Storage Degradation
Storage Degradation refers to how batteries and energy storage systems naturally lose their ability to hold power over time and use. Think of it like how a phone battery doesn't last as long after a year of use. Energy storage professionals work on understanding, measuring, and reducing this loss of performance in large-scale batteries used in renewable energy systems, electric vehicles, and power grids. This is a critical concern because it affects how long expensive battery systems will last and how well they'll perform over their lifetime.
