Recently, researchers at the Georgia Institute of Technology discovered that sodium-based batteries and potassium-based batteries are expected to replace traditional lithium batteries
.
? Researchers once believed that one of the biggest obstacles facing sodium-based and potassium-based batteries is that they will decay and degrade more quickly, and have a lower energy density than lithium-ion batteries
.
But this is not always the case
.
When researchers studied the reaction of lithium ions, sodium ions, and potassium ions with iron sulfide particles, they found that sodium and potassium and iron sulfide are more stable during the reaction, which indicates that battery life based on sodium or potassium may be much longer than expected
.
? The study also questioned the view that the large volume changes that occur in electrochemical reactions are always the precursor to particle fracture
.
This fracture will cause the electrode to fail, which in turn leads to battery degradation
.
Although there is still a lot of work to be done, this research will help design new materials for battery systems
.
? With the advancement of battery technology, more and more electric vehicles have appeared in people's vision, which has also raised people's concerns: it may lead to the exhaustion of the supply of metal lithium
.
Therefore, although the current energy density of sodium-based and potassium-based batteries is not high, their content in the earth's crust is 1,000 times more abundant than lithium, which is very important for large-scale energy storage, such as backup power for homes or power grids.
