Quick student answer

What should you know about (chemistry only) Explain that rechargeable cells and batteries can be recharged because their chemical reactions are reversed by an external electrical current?

Direct answer

In Chemistry, this page helps you answer questions about (chemistry only) Explain that rechargeable cells and batteries can be recharged because their chemical reactions are reversed by an external electrical current within Chemical cells and fuel cells (chemistry only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Rechargeable cell and External electrical current.

Key terms

  • Rechargeable cell: A cell whose electrochemical reaction can be reversed by applying an external electrical current, allowing it to be recharged and used repeatedly.
  • External electrical current: An externally applied flow of electrons that drives the reverse of the cell’s spontaneous reaction, restoring the original reactants and enabling the cell to be reused.

Common trap

Misunderstanding Rechargeability: Explain that while rechargeable cells can be recharged multiple times, their capacity decreases over time due to chemical degradation.
