Question
What condition must be met for a battery to be rechargeable?
• The battery must be open to the outside so that it can vent any internal
pressure that builds up from gases within it.
• It must generate electricity via an acid™base reaction rather than via an
oxidation reduction reaction.
Either its anode or its cathode must generate a gas as a result of the
electrochemical reaction.
• The electrochemical reaction of the battery must be reversible.
Answer
The electrochemical reaction of the battery must be reversible.
