The NCC improved Gassner's model by replacing the plaster of Paris with coiled cardboard, an innovation that left more space for the cathode and made the battery easier to assemble. It was the first convenient battery for the masses and made portable electrical devices practical, and led directly to the invention of the flashlight.

A device used as a toy and made out of wood. [41] Spruce beer – a beverage made using pine needles. Also called pine beer and nettle beer, it was most likely originally brewed by First Nations, and predates the arrival of Europeans. [42] Squash – the people of southern Mexico were the first to grow squash. Squash along with maize (corn) and ...
Schematic diagram of a copper–zinc voltaic pile. Each copper–zinc pair had a spacer in the middle, made of cardboard or felt soaked in salt water (the electrolyte). Volta's original piles contained an additional zinc disk at the bottom, and an additional copper disk at the top; these were later shown to be unnece
By the time of the American Civil War, Grove's battery had been replaced by the Daniell battery. In 1841 Robert Bunsen replaced the expensive platinum electrode used in Grove's battery with a carbon electrode. This led to large scale use of the "Bunsen battery" in the production of arc-lighting and in electroplating.
The Baghdad Battery is the name given to a set of three artifacts which were found together: a ceramic pot, a tube of copper, and a rod of iron. It was discovered in present-day Khujut Rabu , Iraq in 1936, close to the metropolis of Ctesiphon , the capital of the Parthian (150 BC – 223 AD) and Sasanian (224–650 AD) empires, and it is ...
