A storage battery is comprised of one or more rechargeable cells of the ______, or other rechargeable electrochemical types.

A storage battery, often used in various applications such as automotive, solar energy storage, and portable electronics, is primarily made up of rechargeable cells. The correct answer identifies lead-cadmium or nickel-cadmium as types of rechargeable electrochemical cells that are commonly used in storage batteries.

Lead-cadmium batteries have been widely utilized due to their ability to provide a reliable source of power, particularly in industrial settings, and are known for their robustness in various environmental conditions. Nickel-cadmium batteries also have a long history of use, offering advantages like high discharge rates and a longer lifecycle, although they can suffer from memory effects.

While other cell types, like lithium or alkaline, are indeed used in batteries, they do not typically fall under the categorization of rechargeable batteries in the context presented. Alkaline batteries are mostly non-rechargeable, and while lithium can be used in rechargeable formats, it is more classically associated with other types of batteries that often do not fall into the traditional storage battery category outlined here.
