EV Technology - Future Battery Technologies
Which of the following correctly describes the electrolyte in lithium-sulfur batteries?
AA liquid that allows lithium ions to move between electrodes
BA solid metal conductor
CA gas that stores electrical energy
DA polymer that blocks ion movement
Step-by-Step Solution
Solution:
  1. Step 1: Understand electrolyte function

    The electrolyte in lithium-sulfur batteries is a liquid or gel that permits lithium ions to travel between the anode and cathode.
  2. Step 2: Rule out incorrect descriptions

    Electrolytes are not solid metals, gases, or polymers that block ions.
  3. Final Answer:

    A liquid that allows lithium ions to move between electrodes -> Option A
  4. Quick Check:

    Electrolyte = Ion conductor liquid [OK]
Quick Trick: Electrolyte lets lithium ions flow inside battery [OK]
Common Mistakes:
  • Thinking electrolyte is a solid metal
  • Confusing electrolyte with electrode
  • Assuming electrolyte blocks ions
