Lithium-ion batteries are currently the most concerned energy storage technology. According to the statistics of the US Department of Energy, by the end of 2016, the installed energy storage capacity in the United States, Japan, the European Union and China accounted for 94% of the global installed capacity, of which nearly 100 were demonstrations of electrochemical energy storage. The number of projects accounted for 53%. In the number of electrochemical energy storage demonstration projects, lithium-ion batteries account for the highest proportion, reaching 48%, ranking the highest in battery energy storage. In the future, the new generation of lithium-ion battery technology will bring fundamental changes to the battery's safety, energy density, charging time and other indicators, and has broad applications in the fields of power grid peak regulation and frequency regulation, electric vehicles, commercial/home energy storage systems, etc. prospect.
The flow battery has the advantages of large capacity and low cost, and can be built into an economical and reliable energy storage power station of more than 100,000 kilowatts, providing important support for improving the flexibility of power grid dispatch control and large-scale development of new energy. The construction and operation of energy storage power stations in large energy bases, central substations, load centers, power grid terminals and other areas can provide a variety of auxiliary services such as peak regulation, frequency regulation, and voltage regulation. power grid emergencies and other aspects play an important role. The configuration of a large-capacity liquid flow energy storage system in the new energy power generation base can effectively suppress the fluctuation of new energy power generation output, flexibly track the power generation plan curve, and promote new energy power generation to become the main power source.
Based on the judgments of the International Renewable Energy Agency, the International Energy Agency and other institutions, lithium-ion and flow batteries will break through the technical bottleneck around 2030, and the overall performance of the battery will be improved in an all-round way, becoming the mainstream battery technology with the most large-scale commercial prospects, accounting for the global market share. The proportion of energy storage battery capacity will exceed 50%, which will greatly promote the development and application of energy storage battery technology.
