A secondary cell is actually a type of rechargeable battery. The confusion might come from the terminology.
Hereβs a breakdown:
1. **Primary Cells**: These are non-rechargeable batteries. Once depleted, they cannot be recharged and used again. Examples include alkaline batteries, zinc-carbon batteries, and lithium non-rechargeable batteries.
2. **Secondary Cells**: These are rechargeable batteries. They can be used multiple times by recharging them after they are depleted. Examples include lead-acid batteries, nickel-cadmium (NiCd) batteries, nickel-metal hydride (NiMH) batteries, and lithium-ion (Li-ion) batteries.
So, the type of battery cell that **cannot** be recharged is not a secondary cell but a **primary cell**.
