Question
By passing the electricity through electrochemical cells, they can be
- Recharged
- Charged
- Discharged
- Deployed
Hint:
By passing electricity, the anolyte and catholyte get energy and the electrochemical cells get recharged.
The correct answer is: Recharged
By passing electricity through the electrochemical cells, they can be recharged.
- By passing electricity through the anolyte and catholyte they acquire energy.
- Some primary cells can't be recharged and they are discarded after use.
