Episode notes
Battery Components
- Basic batteries have two electrodes (anode and cathode) and an electrolyte.
- Modern batteries aim to replace flammable liquid electrolytes with safer, solid ceramic ones.
Cathode Materials
- Cathodes often use scarce, ethically problematic metals like cobalt.
- Scientists explore earth-abundant alternatives like iron and manganese for more sustainable batteries.
Consumer Concerns and Infrastructure
- Consumers experience "range anxiety" regarding battery life.
- Infrastructure and policy changes are needed to support wider adoption of electric vehicles and alternative transportation.
