n advanced energy technology "twelfth five-year" 863 plan "high performance chemical energy storage battery key technology research and demonstration plants" theme projects, supported by "can ratio, low cost of the new super capacitor is a key technology research", "long life manganese acid lithium battery storage key technology and demonstration" subjects have made major progress, recently passed the technical acceptance.

According to the ministry of science and technology official weibo "sharp technology" on August 15, in terms of "new super capacitor", break through the high energy density of long life and high power density of super capacitor preparation technology bottleneck, developed a porous graphene, high pressure and electrolyte salts and electrolyte, such as cellulose membrane materials, developed a dry preparation of electrodes pilot technology, breaking the 3.0 V / 12000 (f) the core of the supercapacitor industrialization technology, products have been in the aspect of mechanical energy recovery, super capacitor railway vehicles at home and abroad for application. At present domestic in super capacitor from material and devices to the system integration has become the core technology system, change the super capacitor during the 11th five-year plan by foreign products monopoly situation.

In "the long life of manganese acid lithium battery storage", carried out the layered lithium manganese acid, coated on the surface of single crystal manganese acid lithium cobalt, aluminum, asphalt were doped manganese acid lithium battery anode materials and resins derived hard carbon anode materials and electrolyte function research, as well as single cells, modules, and energy storage system research, master the long life and low cost lithium-ion energy storage system of the industrialization of the key technology, single life is more than 3000 times, up to 6000 times. After the first of its kind in the international became 2 set of 50 kw / 100 KWH of layered hard carbon manganese acid lithium/lithium ion battery energy storage system development and demonstration of operation; At the same time developed a 20 KWH of household solar energy storage systems, 3 KWH standby emergency power supply, etc. To demonstrate the application.


On "all solid state lithium ion battery storage", successfully developed the high conductivity of Li2S - P2S5 binary system and Li2S GeS2 - P2S5 ternary system of solid electrolyte, mastered the Li2S - P2S5 system glass ceramic solid electrolyte materials preparation methods, the preparation method of the amorphous precursor larger breakthrough, to realize the stability of the high efficient preparation. Currently have implemented sulfide kg of solid electrolyte preparation ability. Developed with core-shell structure and compositional gradient high nickel group layered cathode material. Adopt the dual system of sulphate solid electrolyte and the anode, developed a capacity of 4.0 8.0 Ah Ah and solid-state lithium battery, room temperature cycle times, 500 times, optimized the large solid-state soft package battery assembly process, promote the industrialization of all solid state lithium ion batteries.

Energy storage battery "in" new lithium sulfide, preparation technology, developed a high energy density lithium sulfur batteries developed by 35 ah lithium sulfur batteries than energy 566 wh/kg (25 ℃), has reached the world advanced level. Preliminary developed sulfur 1 KWH lithium-ion battery pack and 12 KWH large-capacity lithium sulfur batteries, achieved its coupling with solar cells power generation demonstration. Using elemental sulfur large-capacity lithium sulfur batteries and battery technology products have used for long-endurance uav airborne energy systems in areas such as potential, popularization and application prospect.

In addition, the "low cost titanium acid lithium storage lithium ion battery", get through the low cost material production, long life, high consistency cells and modules, power station, demonstration and promotion of the whole industry chain based on anode materials for lithium titanate department set up a mobile energy storage demonstration unit, the 0.5 MWh / 1 mw lithium titanate battery energy storage power station of light store application demonstration, for the application of lithium titanate is energy storage laid a foundation.

Project implementation, to a certain extent, to satisfy the large-scale renewable energy and smart grid energy storage requirements, to promote the orderly development of wind power and solar energy and resources reasonable allocation, raise the level of the intermittent renewable energy grid technology, for our country energy storage battery materials - battery - integration - demonstration industry chain provides a more complete technical support system, the sustainable development of the industry for the future to build the industrialization of internationally competitive platform, promote the development of China's energy storage industry, to enhance the strategic position for the sustainable development of China's energy and wide prospect of market.
