Professor Kang claims that this new battery could be used in various sectors, such as electric vehicles. The best part is that it operates with salt.
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance hybrid sodium-ion battery that charges quickly and offers impressive energy density.
This revolutionary prototype uses sodium (Na), a chemical element that is more than 1,000 times more abundant and cheaper than lithium (Li), the main component of conventional batteries.
Generally, sodium-ion batteries face limitations such as lower power, limited storage properties, and prolonged charging times. Here is the study.
The innovative battery design, led by Professor Jeung Ku Kang from the Department of Materials Science and Engineering at KAIST, tackles the current limitations of sodium-ion batteries by integrating the anode materials used in traditional batteries with the cathodes used in supercapacitors. The result offers high storage capacity and fast charging and discharging speed.
A battery that could be the solution to our problems
The development of the hybrid battery relied on improving the energy storage speed of the battery anodes and increasing the relatively low capacity of the supercapacitor cathode materials.
The research team at KAIST used two different metal-organic frameworks to create an optimized synthesis of hybrid batteries, resulting in an anodic material with improved kinetics and a high-capacity cathodic material.
The fully assembled sodium-ion energy storage hybrid device surpasses the energy density of commercial lithium-ion batteries and matches the power density characteristics of supercapacitors.
Professor Kang claims that this new battery, with an energy density of 247 Wh/kg and a power density of 34,748 W/kg, could be used in various sectors, such as electric vehicles, smart electronics, and aerospace technologies.
