Which material acts as the cathode in a typical lithium-sulfur battery?
Which material acts as the cathode in a typical lithium-sulfur battery?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify cathode materials in lithium-sulfur batteries
The cathode in lithium-sulfur batteries is made of sulfur, which reacts with lithium ions during discharge.Step 2: Eliminate other options
Graphite is an anode material in lithium-ion batteries; lithium cobalt oxide is a lithium-ion cathode; nickel metal hydride is unrelated.Final Answer:
Sulfur -> Option BQuick Check:
Cathode = Sulfur [OK]
Quick Trick: Sulfur is the cathode in lithium-sulfur batteries [OK]
Common Mistakes:
- Confusing lithium-ion battery cathodes with lithium-sulfur
- Thinking graphite is the cathode
- Mixing battery chemistries
