New energy storage battery technology has become the hot spot and technological frontier of current research and development
Existing commercial battery technologies include lithium-ion batteries, lead-acid batteries, nickel-hydrogen/cadmium batteries, sodium-sulfur/nickel batteries, etc. These battery technologies are mature and have been widely used in electric vehicles, mobile phones, notebook computers, wind farm energy storage systems, Power grid frequency regulation, distributed power and micro grids and other fields.
Currently, there are more than 30 new energy storage batteries in commercial and demonstration applications, laboratory R&D or conceptual design stages. Among them, the battery technologies that have been demonstrated and applied include ternary material lithium-ion batteries, all-vanadium/zinc-bromine flow batteries, lead-carbon batteries, supercapacitor batteries, 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/non-film and other new-generation flow batteries, aluminum/zinc and other metal-air batteries, sodium/magnesium ion batteries, liquid metal batteries, etc.; graphene supercapacitor batteries, dual carbon batteries, nano Microbatteries, organic batteries, etc. are in the conceptual design stage. These new energy storage battery technologies have become hot spots and technological frontiers in current research and development, and are expected to greatly improve the performance of energy storage batteries and promote large-scale application of energy storage batteries in the future.
Semi-solid flow batteries combine the advantages of lithium-ion and flow batteries, and will achieve a qualitative leap in improving battery energy and power density, reducing size, and reducing costs. At present, the Massachusetts Institute of Technology has developed a semi-solid flow battery with an energy density of 250 Wh/kg, which is more than 10 times higher than the current flow battery, and the cost is only US$100-250/kWh, which is 70% lower than the current above. The graphene lithium battery is made of graphene with high conductivity and ultra-light weight. It uses the characteristics of lithium ions that can quickly shuttle between the graphene surface and the electrode to shorten the charging time to minutes. The Spanish company Graphenano and the University of Corvado have jointly developed the world's first graphene battery for electric vehicles, which takes only 8 minutes to charge and has a cruising range of 1,000 kilometers. The theoretical energy density of lithium-sulfur batteries can reach 2600 Wh/kg, which is 8 to 10 times that of traditional lithium-ion batteries. The energy density of lithium-sulfur batteries developed by Polyplus in the United States and the Fraunhofer Institute for Materials and Beams in Germany has reached 420 Wh/kg and 600 Wh/kg. The aluminum-air battery uses air as the positive electrode and aluminum as the negative electrode, and releases energy through the chemical reaction between aluminum and oxygen. The Israeli company Phinergy has developed an aluminum-air test battery for electric vehicles with an energy density of over 800 Wh/kg and a cruising range of 1,600 kilometers.
