New energy storage battery technology -Lithium - Ion Battery Equipment
Energy storage was rated by Davos Economic Forum as one of the top ten new technologies that may change the world in the future. Energy storage batteries are the most active field in energy storage technology research, development and application. At present, the energy storage battery technology is developing rapidly. Once a breakthrough is made, it will have a significant impact on the development of new energy, power grid operation control, terminal energy use, etc. In the future, energy storage battery technology will be widely used in the new generation power system.(Lithium - Ion Battery Equipment)
New energy storage battery technology has become the hotspot and technology frontier of current research and development
The existing commercial battery technologies include lithium ion battery, lead acid battery, nickel hydrogen/cadmium battery, sodium sulfur/nickel battery, etc. These battery technologies are mature and have been widely used in electric vehicles, mobile phones, laptops, wind farm energy storage systems, grid frequency modulation, distributed power supply, microgrid and other fields.
At present, there are more than 30 kinds of new energy storage batteries in commercial and demonstration applications, laboratory research and development or conceptual design.
Among them, the battery technologies that have been demonstrated and applied include ternary material lithium ion battery, all vanadium/zinc bromine flow battery, lead carbon battery, super capacitor battery, etc; Battery technologies in the laboratory research and development stage include graphene/lithium sulfur/lithium air and other new generation lithium ion batteries, semi-solid/film free and other new generation liquid flow batteries, aluminum/zinc and other metal air batteries, sodium/magnesium ion batteries, liquid metal batteries, etc; Graphene super capacitor battery, dual carbon battery, nano micro battery, organic battery, etc. are in the conceptual design stage.
These new energy storage battery technologies have become the focus of current research and development and the leading edge of technology. In the future, they are expected to significantly improve the performance of energy storage batteries and promote the large-scale application of energy storage batteries.
Semi solid liquid flow battery combines the advantages of lithium ion battery and liquid flow battery, and will achieve a qualitative leap in improving battery energy and power density, reducing volume, and reducing cost. At present, Massachusetts Institute of Technology has developed a semi-solid liquid flow battery. The energy density has reached 250 watt hours/kg, which is more than 10 times higher than the current liquid flow battery. The cost is only 100 to 250 dollars/kilowatt hour, which is more than 70% lower than the current one.
The graphene lithium battery is made of graphene with high conductivity and ultra light weight. The charging time is reduced to minutes by using the characteristics of lithium ion that can shuttle quickly between the graphene surface and the electrode. Spain's Graphenano Company and University of Corvado jointly developed the world's first graphene battery for electric vehicles, which takes only 8 minutes to charge and has a range of 1000 kilometers. The theoretical energy density of lithium sulfur battery can reach 2600 watt hours/kg, 8 to 10 times that of traditional lithium ion battery.
The energy density of lithium sulfur battery developed by American Polyplus Company and German Francoff Institute of Materials and Beams has reached 420 watt hours/kg and 600 watt hours/kg. The aluminum air battery uses air as the positive pole and aluminum as the negative pole, and releases energy through the chemical reaction between aluminum and oxygen. The energy density of the battery can theoretically reach 8100 watt hours/kg, ranking first among all kinds of battery energy density. Phinergy, an Israeli company, has developed aluminum air test batteries for electric vehicles, with an energy density of more than 800 watt hours/kg and a range of 1600 kilometers.
