Integrated energy storage system and its application

With the wide application of clean energy, the technology of energy storage has been greatly developed. Conventionally we use single way of energy storage like lithium battery or lead acid battery. However, except advantages, all these ways of energy storage have their limitation. Take lithium battery for example, it has quick responding time, but it is restricted by time and space. For lead acid battery, its price is lower but it occupies large space and has comparatively slower response. Integrated energy storage system is composed of different ways for energy storage. It will take the most of these storage methods. It is much more effective and economical way of energy storage.
