Lahore: A South Korean research team has achieved a significant breakthrough in battery technology, unveiling next-generation sodium batteries that promise to revolutionize the electric vehicle and consumer electronics industries.
The new sodium batteries, developed by researchers at the Korea Advanced Institute of Science and Technology (KAIST), offer a safer and more affordable alternative to traditional lithium-ion batteries. Sodium (Na), being 500 times more abundant than lithium, makes these batteries more sustainable.
Previously, sodium-ion batteries were limited by long charging times and insufficient storage capacity. However, the KAIST team has successfully addressed these issues by creating a sodium-ion battery with high energy and power that can charge rapidly.
By combining materials typically used in batteries with those suitable for supercapacitors, the researchers have developed a battery with an energy density of 247 Wh/kg and a power density of 34,748 W/kg. Prof. Jeung Ku Kang, who supervised the research, stated that this hybrid sodium-ion energy storage device represents a breakthrough in overcoming the current limitations of energy storage systems.
This breakthrough comes on the heels of a recent discovery by Japanese researchers who developed a novel process for mass-producing sodium solid-state batteries.
The new battery technology not only promises to enhance the performance of electric vehicles by significantly improving charging capacity and doubling the range of existing EVs but also has potential applications in consumer electronics.
Prof. Jeung Ku Kang anticipates that this innovative technology will have broader applications across various electronic devices, potentially eliminating range anxiety and significantly improving the efficiency and sustainability of energy storage systems.
