A new sodium battery that can be charged in seconds has been developed

In this blog, I will talk about the developments regarding the sodium battery.

Battery technologies continue to be researched specifically for sodium, which is found in more abundant amounts than lithium. In this context, a sodium battery that can be charged in just a few seconds was developed.

Sodium, which is 500 times more abundant than lithium, has recently attracted great attention due to its potential in sodium-ion battery technologies. However, existing sodium-ion batteries have been criticized for facing fundamental limitations such as lower power output, limited storage capabilities and longer charging times compared to lithium-ion batteries. But researchers have developed a new sodium battery that can be charged in just a few seconds.

The most important vulnerability of sodium batteries has been resolved

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) announced that they have developed a new high-energy, high-power hybrid sodium-ion battery (SIHES) with fast charging capability. In innovative hybrid energy storage systems, the research team integrated anode materials typically used in batteries with cathodes suitable for supercapacitors. Thus, both high storage capacities and fast charge-discharge rates were achieved.

The newly developed combined full cell, consisting of anode and cathode, paves the way for high-performance hybrid sodium-ion batteries. It is stated that these batteries exceed the energy density of commercial lithium-ion batteries. With this development, hybrid sodium-ion systems are expected to be suitable for use in various applications ranging from electric vehicles to smart electronic devices and aviation technologies.

While existing sodium ion energy storage systems provide a relatively high energy density, they exhibit poor performance in terms of rechargeability because they have a low power density. That's why researchers are focusing on sodium-ion hybrid energy storage (SIHES) cells. This storage system is quite impressive as it can simultaneously allow high energy density and fast-chargeable power density.
