From the perspective of the system, cascade phase change energy storage (CPCES) technology provides a promising solution. Numerous studies have thoroughly investigated the critical parameters of the energy storage process in the CPCES system, but there is still a lack of relevant discussion on the current status and bottlenecks of this technology.
