Question

The number of positive plates in a lead acid battery cell are

Answer 1

Explanation:

the batttery consists Of two lead plates

Answer 2

A battery cell is made up of two lead plates: a positive plate covered with lead dioxide paste and a negative plate composed of sponge lead, separated by an insulating substance (separator).

The following are some facts about lead-acid batteries:

• The lead-acid battery was designed in 1859 by French scientist Gaston Planté and is a form of rechargeable battery.
• It's the very first rechargeable battery ever made.
• Lead-acid batteries have a poor energy density when compared to current rechargeable batteries.
• Despite this, the cells have a high power-to-weight ratio due to their capacity to provide strong surge currents.
• These characteristics, along with their low cost, make them appealing for use in automobiles to supply the high current needed by starting motors.
• The chemical energy of the battery is stored in the potential difference between pure lead on the negative side and PbO2 on the positive side, as well as the aqueous sulfuric acid, in the charged state.
• The energy released when the strong chemical bonds of water (H2O) molecules are created from H+ ions of the acid and O2 ions of PbO2 can be ascribed to the electrical energy produced by a discharging lead-acid battery.
