Discussion
Which one of the following statements is correct regarding lithium and alkaline batteries ?
Answer: B
The correct statement is that alkaline batteries exhibit a gradual decrease in voltage output over time.
As an alkaline cell discharges, its voltage falls steadily from about 1.5 V. Lithium cells hold a much flatter voltage for most of their life and then drop off sharply near the end.
The other statements are reversed. Ordinary alkaline cells are primary cells, not designed to be recharged, so 'both generally rechargeable' is wrong. Lithium batteries have a higher energy density than alkaline batteries, which is why they are used in phones and laptops, and it is lithium, not alkaline, that keeps a consistent voltage.
