Energy storage limitations

Definition

Energy storage limitations refer to the challenges and constraints associated with storing energy efficiently for later use, particularly in small-scale applications like autonomous environmental sensors. These limitations include factors such as capacity, efficiency, degradation of storage materials, and the ability to maintain a stable energy supply over time. In the context of energy harvesting, understanding these limitations is essential for developing effective systems that can reliably power sensors without continuous external energy input.
