A group of researchers from the Korea Advanced Institute of Science and Technology (Korea Advanced Institute of Science and Technologyor KAIST) developed a high power sodium ion batterywhich can be recharged in a few seconds — which might be a viable alternative to lithium-ion cells, used in most devices today.
Although sodium ion batteries already exist, they tend to have low energy storage capacity and recharge more slowly — which is a shame, given that sodium is much more abundant in nature than lithium (and much more geographically diverse). ).
To resolve these deficiencies, the researchers developed a type of hybrid battery, work that was carried out by integrating the anode that is normally used in batteries with cathodes made with materials commonly used in supercapacitors.
This crossover, according to the researchers, allowed the battery to achieve high storage capacities and fast charge/discharge rates, surpassing the energy density of lithium-ion batteries — which, at least in theory, would solve the main problems of batteries. sodium batteries.
To give you an idea, the resulting hybrid battery might be recharged around 30 times faster than current batteries — an efficiency that might be very useful if used in batteries not only for smartphones, but also for vehicles and aerospace technologies.
Interesting (and promising), don’t you think?
