When analyzing the energy storage process, the part of the object or spatial range delineated to determine the research object is called an energy storage system. It includes the input and output of energy and matter, as well as the conversion and storage equipment of energy. Energy storage systems often involve multiple types of energy, devices, substances, and processes, and are complex energy systems that change over time, requiring multiple indicators to describe their performance. The commonly used evaluation indicators include energy storage density, energy storage power, energy storage efficiency, energy storage price, and impact on the environment
Energy storage system requirements
There are different energy storage requirements for different application purposes, but in summary, a good energy storage system has the following common characteristics ① The energy stored per unit volume (volumetric heat storage density) is high, which means that the system stores as much energy as possible. High energy batteries, for example, are popular among consumers due to their higher energy density and longer lifespan compared to regular batteries ② has good load regulation performance. When using an energy storage system, it is necessary to adjust the amount of energy released according to the requirements of the energy user. The performance of load regulation determines the quality of system performance ③ Energy storage efficiency should be high. Energy storage cannot be separated from energy transfer and conversion technology, so the energy storage system should be able to receive and release energy at the maximum rate without excessive driving force. At the same time, minimize losses such as leakage, evaporation, and friction during the energy storage process as much as possible, and maintain high energy storage efficiency
