š Key Concepts
⢠Primary vs. secondary cells in batteries
⢠What happens to electrodes during discharge and recharge
⢠The difference between rechargeable and nonārechargeable batteries
š Think About
⢠Think about common household disposable batteries: are they meant to be recharged, and why or why not?
⢠If a batteryās electrode material is physically consumed or eroded during use, what does that imply about restoring it by charging?
⢠Compare what is true about all primary cells versus what might be true only about some battery types.

Before You Answer
⢠Clarify the definition of a primary cell (singleāuse vs multiāuse).
⢠Check whether attempting to recharge a primary cell changes the fact of whether it can or cannot be properly recharged.
⢠Make sure each chosen option must be always true for primary cells, not just sometimes true.
