This new battery is fully charged in a few seconds

Lithium batteries have many advantages, but the main disadvantage is that obtaining lithium is not as easy as some other sources. Researchers from Korea have now created a sodium battery that not only relies on an abundant source, but also charges extremely quickly.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a sodium-ion battery that should soon be much easier to produce than the lithium batteries now widely used. Sodium is easy to obtain and is excellent at storing energy. The researchers believe they have a very suitable alternative to the lithium battery.

Sodium ion battery

Sodium-ion batteries aren't exactly new, but they have always been difficult to recharge due to their low energy density. That's why researchers used hybridization to solve this problem. At the end of last year, we wrote about the Swedish company Northvolt, which developed a battery that can store 160 watt-hours per kilogram. the Koreans However, it now comes with a battery that can store 247 watt-hours per kilogram.

The new anode and cathode allow the cell to operate in a sodium-ion hybrid energy storage device, exceeding the energy density of its lithium brother. “Developing a hybrid battery with high energy density and high energy density requires an improvement in the slow energy storage rate of battery-type anodes and an improvement in the relatively low capacity of supercapacitor-type cathode materials,” the team said. This could work well with smartphones, but also with electric cars and even larger power grids.
