What characterizes secondary batteries in device energy management?

Secondary batteries, known as rechargeable batteries, play a crucial role in device energy management due to their ability to store energy for later use, which is particularly valuable in applications where energy harvesting is implemented. These batteries are often paired with energy harvesting solutions, such as solar panels or thermoelectric generators, which continuously produce energy from ambient sources. This pairing allows devices to not only utilize immediate energy harvested but also store excess energy for use when harvesting is insufficient, thereby enhancing the overall energy efficiency and reliability of the system.

This integration is particularly beneficial for IoT devices or sensors that operate in environments where power supply may be intermittent. By charging the secondary batteries using harvested energy, devices can maintain functionality over extended periods without relying solely on traditional power sources.

Understanding the relationship between secondary batteries and energy harvesting highlights how energy management strategies can optimize performance and extend the operational lifespan of devices in various applications.
