Abstract: Energy-storing technology plays an important part in energy conversion and its application holds the key to renewable development and the destiny of energy Internet construction. Energy-storing technological development and application have been regarded more and more important in various countries, leading to a significant progress in the related key systematic technologies. A series of technologies is brought under or close to industrialization, such as aircompressed energy-storing technology, flow battery, and lithium-sulfur battery. Hydrogen fuel cell, as the main direction for fuel cell, comes under a wider application. Heat-storing technology is also experiencing a rapid development but requires more attention from the market. Propelled by rapid development of renewable energy, electric-powered vehicle and energy Internet industries, energy-storing industry has a trend for explosive growth. With a continual decline in storage cost of renewable electricity, application scale and technological cost of energy-storing system will enter into a new stage of positively-cycled development. Battery technology for electric-powered vehicles is expected to see a significant breakthrough with a promising market prospect.
