Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have introduced a groundbreaking and affordable sodium-based battery, as detailed in a study published in the scientific journal Energy Storage Materials.
The team asserts that sodium-ion batteries surpass traditional lithium-ion counterparts in several aspects, particularly in terms of cost-effectiveness. Sodium is a thousand times more abundant than lithium, making it significantly cheaper and more accessible.
Previous research indicated that alternative sodium-based batteries suffered from low output power, storage limitations, and lengthy charging times. However, the KAIST team has successfully addressed these issues by employing new anode materials.
The researchers highlight that their hybrid sodium-ion battery boasts a high energy density of 247 watt-hours per kilogram and a power density of 34,700 watts per kilogram.
These batteries hold potential for use in electric vehicles, among other applications, the scientists noted.
