New sodium battery that can be charged in seconds developed [Video]

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a high-power hybrid sodium-ion battery that can be charged in seconds. 

Sodium is considered nearly 1000 times more abundant than lithium. Therefore, sodium-ion electrochemical energy storage devices are more appealing than traditional lithium-ion electrochemical energy storage.

Led by Professor Jeung Ku Kang from the Department of Materials Science and Engineering, the research team integrated anode materials typically used in batteries with cathodes suitable for supercapacitors.

The combination helped the battery to achieve high storage capacities and rapid charge-discharge rates. The study indicates that the battery can be a viable next-generation alternative to lithium-ion batteries.
