Solid-state batteries (SSBs) offer higher energy densities compared to traditional lithium-ion batteries. Lithium-ion batteries typically have an energy density below 300 Wh/kg, whereas solid-state batteries can exceed 350 Wh/kg, with some advanced versions reaching as high as 500 Wh/kg, such as Samsung SDI’s latest technology. This significant increase in energy density allows solid-state batteries to store more energy in the same volume, making them more suitable for applications like electric vehicles where range and efficiency are critical.
Here is a comparison of the energy densities:
| Battery Type | Energy Density |
|---|---|
| Lithium-ion | Below 300 Wh/kg |
| Solid-State (Basic) | 350-500 Wh/kg |
| Solid-State (Advanced) | Up to 500 Wh/kg |
These advancements make solid-state batteries an attractive option for improving the driving range and safety of electric vehicles by offering better performance and reducing the risk of fires.
