Current lithium batteries need to be improved because they are not comparable to other components, their evolution is solid state batteries, what are the differences.
Lithium batteries vs. solid-state batteries, differences and advantages
Although it may surprise you, the new solid-state batteries are actually the evolution of lithium batteries, so they also use lithium.
You need to understand that rechargeable lithium batteries typically employ a physical separator and use liquid electrolyte, which increases the likelihood that the batteries will develop dendrites, needle-like structures made of lithium deposition that can eventually puncture the separator and short-circuit the system.
With a liquid electrolyte, a separator is required to prevent the occurrence of short circuits, but with a solid electrolyte it would not be necessary because it separates them by itself.
The key difference between a lithium battery and a solid-state battery is that the former uses a liquid solution to regulate current flow, while solid-state batteries opt for a solid electrolyte.
Why do lithium batteries explode?
Recently, the technologies used in battery manufacturing, such as packaging technology, have improved, but so far there seems to be no end to accidents involving battery deformation, expansion and ignition due to overheating.
So finding a solid alternative to a solution that until recently was liquid is a major breakthrough.
Other all solid state batteries benefits:
- Cooler batteries: they heat up less and this leads to better performance.
- Batteries more resistant to extreme temperatures: they are currently working to reach -60ºC so they will be able to withstand between -60ºC and 60ºC.
- Space saving: conventional liquid battery separators are thicker than conventional liquid battery separators.
- More battery in less charging time: they could charge up to 6 times faster than normal.
- Battery life: if they last about 2 years or so now, they will last about 10 years.
- Safer batteries: solid-state electrolytes are less reactive than liquids so batteries will not explode or catch fire if damaged or suffer from manufacturing defects.
- Higher charge capacity: they will be able to store much more energy, which will allow double the time of use.
