Energy storage technology(EST) as a key technology and effective means to deal with the intermittence and volatility of renewable energy. The energy storage industry in China is still in the early commercial stage due to its cost and technical reasons. The development of an industry is always affected by a variety of factors, and energy storage industry is no exception. This paper summarizes the basic concepts of evolutionary game(EG) theory and analyzes the factors that affect the development of energy storage industry: driving behavior by government forces, market demand and technological innovation, constructs an EG dynamic system model, analyzes the strategic choice among enterprises, scientific research institutions and governments in the process of collaborative innovation of EST. The influence of government supervision intensity and the proportion of synergistic benefits on the evolution trend of the system are analyzed, and some suggestions are given to promote the evolution of energy storage industry in China. The results show that whether enterprises and scientific research institutions adopt the "active cooperation" strategy in the process of collaborative innovation of EST is influenced by many factors, such as government input and supervision intensity, the input cost and benefits of partners, and technology spillover benefits.
