Salt batteries or sodium ions?
Let’s make a small summary:
Some people define the sodium ion batteries as "salt batteries" for the element on which they pivot but it is a simplification too high because the actual salt batteries have different characteristics. The salt battery is a thermal battery, which stores energy in the form of heat and releasing it when needed. They are mostly used in stationary systems.
Explained this, sodium ion batteries, on the other hand, are a type of rechargeable battery and use ions for charging and discharging cycles, taking advantage of the shift from cathode to anode of ions during charging and the reverse to yield energy outside.
There are many features that could be listed but for now we keep it simple.
Sodium ion batteries begin their life when companies producing electric car accumulators have started to think about using an alternative material to lithium that was:
- easier to find
- cheaper
- easier to dispose of
- less negative impact on the environment
Sodium ion batteries, however, compared to lithium batteries:
- have lower energy density
- reach greater weights to "realize" the same amount of energy
There are many technologies that over time have established themselves as ecological alternatives and these batteries are among them. So this is something positive that, however, is not applicable to sectors other than stationary plants.
Today, in fact, is difficult to beat the high efficiency of lithium batteries, which have a high energy density and ability to ensure excellent performance over time. That’s why we at Galvani Power rely on this technology!
