Scientists Develop Battery Capable of Rapid Charging in Just a Few Seconds

KAIST researchers have actually established a breakthrough hybrid sodium-ion battery with high power and energy density, appealing fast charging for applications in electric lorries and other sophisticated technologies.Sodium (Na), being more than 500 times as plentiful as lithium (Li), has recently attracted considerable interest for its prospective use in sodium-ion battery technologies.However, existing sodium-ion batteries deal with basic constraints, consisting of lower power output, constrained storage properties, and longer charging times, necessitating the advancement of next-generation energy storage materials.On the 11th of April, KAIST (represented by President Kwang Hyung Lee) announced that a research study group led by Professor Jeung Ku Kang from the Department of Materials Science and Engineering had developed a high-energy, high-power hybrid sodium-ion battery capable of quick charging.Electrochemical characterizations of FS/C/G -20// ZDPC SIHES full cells (left). It is anticipated to be suitable for rapid charging applications ranging from electric lorries to wise electronic devices and aerospace technologies.Professor Kang kept in mind that the hybrid sodium-ion energy storage gadget, capable of fast attaining an energy and charging density of 247 Wh/kg and a power density of 34,748 W/kg, represents an advancement in overcoming the current limitations of energy storage systems. He prepares for wider applications throughout various electronic gadgets, consisting of electrical vehicles.Reference: “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface location O-doped cathode of 3D porous N-rich graphitic carbon structures for high-performance sodium-ion hybrid energy storages” by Jong Hui Choi, Dong Won Kim, Do Hwan Jung, Keon-Han Kim, Jihoon Kim and Jeung Ku Kang, 27 March 2024, Energy Storage Materials.DOI: 10.1016/ j.ensm.2024.103368 The study was carried out with assistance from the Ministry of Science and ICT and the National Research Foundation of Korea through the Nanomaterial Technology Development Project.
