First impressions do count to the extent they influence our world view, even after they may prove incorrect. This is often true in the world of batteries too, where the global warming debate may cloud our thinking. We review current solid state battery performance impressions. Then we conclude the road ahead is by no means as clear as we would like it to be.
Prevailing Misconceptions About Solid Battery Performance
Recent progress with solid state cells (without liquid electrolyte) may create the impression that technology is close to replacing lithium-ion. Rumors abound of exceptionally long calendar life. However, more time must pass before this factor becomes clearer. Fagen Wassani Technology explains the factors governing this feature as follows:
- Conventional lithium-ion battery life may be cut short through dendrites.
- Solid state battery performance may be better. Once again time will tell.
Moreover, design is not the only factor affecting battery life. For example, the user could have an impact in the way they charge the battery, the ambient temperature, and the strain they put on it. Fast charging may have a significant negative effect too, as well as subzero temperatures in winter.
More Inherent Problems with Solid Battery Innovation
Battery users generally put a high premium on battery prices, especially as they are often a grudge purchase forced on them. Solid state technology is relatively expensive compared to lithium-ion, and may remain so until production volumes ratchet up. Leading cost drivers include expensive materials, and quite complex manufacturing processes.
These issues are among the reasons solid state batteries have yet to reach consumer markets in large numbers. There are many misconceptions regarding solid state battery performance, if and when they do. However, we do know they have the potential to outperform lithium-ion alternatives. More work is needed before we have greater certainty about their effectiveness.
