South Korean scientists develop new storage technology to charge 100 times faster than lithium batteries

On Monday, South Korea's Ministry of Science, ICT and Future Planning Department announced that a team of scientists successfully developed new hybrid energy storage technologies that charge much faster than conventional batteries.

Science, ICT, Future Planning said: "The new hybrid energy storage technology combines the benefits of Lithium Batteries with the benefits of a supercapacitor with higher energy densities and 100 times faster charging times than lithium batteries." The research team Led by Kang Jeung-ku, he is a professor at the Graduate School of Energy, Environment, Water and Sustainability at the Korea Advanced Institute of Science and Technology. During the course of the research, a team called Hybrid Interface Materials (HIM) supported the research and was a research arm of the science, ICT and future planning department. September 23, the research results have been published in the international science magazine "Advanced Energy Materials" (Advanced Energy Materials).

HIM executives said in a statement: "Researchers have developed a new raw material with higher energy density and superior energy input and output capabilities ... In the future, new technologies will create a battery for automotive and mobile devices According to the research, we will continue to research and develop, look for the best manufacturing process, improve the production capacity, and in the future, we will also authorize the technology and establish the joint venture business. "

South Korean scientists have developed a new battery that can replace lithium batteries

The general installation of electronic equipment are lithium batteries. Lithium Battery energy storage density of about 185Wh / kg (185 W per kg), slow charging speed, output power 200W / kg (200 W per kilogram). Supercapacitors charge very fast and output about 20 kW / kg (20 kilowatts per kilogram), but the energy density is low, making them less suitable as automotive batteries because the car requires a battery with the highest possible energy density and output power .

The team of scientists has developed a porous nanotube with excellent mesopores that allow positive ions and negative ions to pass through, and then the research team combined new materials with the benefits of lithium batteries and supercapacitors. The new hybrid energy storage technology allows the battery energy density of 275Wh / kg, equivalent to 1.5 times the lithium battery, charging and output power of 23kw / kg, 100 times faster than the lithium battery. The research department said: "With the support of new technologies, if the maximum power output, the battery can be charged within 30 seconds when charging energy density of 200Wh / kg, 20 seconds can reach 130Wh / kg."
