Scientists design super-battery with affordable Na element

super-battery with Na element

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-performance, hybrid sodium-ion battery that promises to revolutionize the energy storage industry. The battery uses sodium (Na), a chemical element that is over 1,000 times more abundant and less expensive than lithium (Li), which is the primary component in most conventional batteries.

Overcoming Sodium-Ion Battery Limitations

Sodium-ion batteries have traditionally faced challenges such as lower power output, limited storage capacity, and longer charging times compared to lithium-ion batteries. The KAIST research team, led by Professor Jeung Ku Kang of the Department of Materials Science and Engineering, addressed these limitations by integrating traditional battery anode materials with the cathodes used in supercapacitors to create a hybrid system. This innovative approach results in high storage capacity and rapid charge-discharge rates.

Optimized Design for Enhanced Performance

The team optimized the hybrid battery’s design by improving the energy storage rate of the anode materials and enhancing the relatively low capacity of supercapacitor-type cathode materials. They utilized two distinct metal-organic frameworks to synthesize the hybrid battery, creating an anode with improved kinetics and a high-capacity cathode material.

Impressive Energy and Power Densities

The fully assembled hybrid sodium-ion battery surpasses the energy density of commercial lithium-ion batteries and matches the power density of supercapacitors. With an energy density of 247 Wh/kg and a power density of 34,748 W/kg, the battery holds great potential for various industries, including electric vehicles, smart electronics, and aerospace technologies.

Publication and Impact

The findings of the research, co-authored by KAIST doctoral candidates Jong Hui Choi and Dong Won Kim, were published in the international journal Energy Storage Materials. The study, titled “Low-crystallinity conductive multivalence iron sulfide-embedded S-doped anode and high-surface-area O-doped cathode of 3D porous N-rich graphitic carbon frameworks for high-performance sodium-ion hybrid energy storages,” outlines the technical breakthroughs achieved and the potential applications of this new battery design.

The development of this hybrid sodium-ion battery marks a significant step toward affordable, efficient, and sustainable energy storage solutions. As the technology matures, it may play a pivotal role in the future of clean energy and advanced electronics.
