An electric vehicle manufacturer wants to improve battery safety and charging speed. Which feature of solid-state batteries should they focus on to achieve both goals?
AIncreasing the battery size to hold more liquid
BReplacing liquid electrolytes with solid electrolytes
CUsing liquid electrolytes with higher voltage
DReducing the number of battery cells
Step-by-Step Solution
Solution:
  1. Step 1: Identify safety and charging factors

    Safety improves by removing flammable liquid electrolytes; charging speed improves with solid electrolytes' efficient ion movement.
  2. Step 2: Choose the feature that addresses both

    Replacing liquid electrolytes with solid electrolytes directly improves safety and charging speed.
  3. Final Answer:

    Replacing liquid electrolytes with solid electrolytes -> Option B
  4. Quick Check:

    Solid electrolyte = safer + faster charging [OK]
Quick Trick: Solid electrolytes improve safety and charging speed [OK]
Common Mistakes:
  • Thinking bigger liquid batteries are safer
  • Assuming liquid electrolytes can be safer
  • Reducing cells lowers safety and speed
