The direction of flow of electricity in an electrolytic cell is the opposite from the flow when a battery is being used to power an external circuit, and the roles of the two poles or electrodes are reversed. Thus some writers will refer to the positive pole of a battery as its “cathode”.
The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy. The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate).
The container stores chemical energy which is converted into electrical energy by the help of the plates. 1. Container – The container of the lead acid battery is made of glass, lead lined wood, ebonite, the hard rubber of bituminous compound, ceramic materials or moulded plastics and are seated at the top to avoid the discharge of electrolyte.
Negative plates in all lead-acid cells are the flat pasted type. The Manchex type is shown in Figure 3-1. The grid is cast with low antimony lead alloy. The button or rosette is a pure lead ribbon which is serrated and rolled into a spiral form. These in turn are pressed or wedged into the holes of the grid.
A lead-acid battery is composed of a series of cells, each of which includes two types of lead plates – one coated with lead dioxide and the other made of sponge lead – submerged in a sulfuric acid solution. This sulfuric acid solution, also known as electrolyte, acts as a catalyst to prompt the chemical reaction that produces electricity.
Normally, as the lead–acid batteries discharge, lead sulfate crystals are formed on the plates. Then during charging, a reversed electrochemical reaction takes place to decompose lead sulfate back to lead on the negative electrode and lead oxide on the positive electrode.

"Ground" vs. "Earth" vs. common vs. negative terminal
A. The positive terminal in a circuit is what creates voltage. Voltage is a potential, so given that it is the positive ions in, say, a battery, which are generally fixed in place, it makes sense that the + terminal in a circuit would create voltage.. B. The negative terminal in a circuit is what provides current. Current is the flow of electrons, and that flow is towards the terminal …
Operation of Lead Acid Batteries
As the above equations show, discharging a battery causes the formation of lead sulfate crystals at both the negative and positive terminals, as well as the release of electrons due to the change in valence charge of the lead. The formation of this lead sulfate uses sulfate from the sulfuric acid electrolyte surrounding the battery.

Due to this current, the sulphuric acid H 2 SO 4 is disassociated into positive H 2 and negative SO 4 Ions. The external load current flows from anode to cathode, but the internal current flows from cathode to anode through the electrolyte. Therefore the positive H 2 ions move to the anode and the negative SO 4 ions move to the cathode.

electrostatics
No, you won''t get shocked by one pole of a battery, not even if you are grounded. This is because even though your body is conductive and connected (usually with some non-zero resistance) to the ground, touching only one pole will cause only transient, very quick and very small redistribution of electric charge to get the battery pole at the same potential your body …

How Do You Identify the Positive End of a Battery?
These two charges have to be kept apart in batteries, so they don''t mix, which is why both types of poles are on opposite sides of most battery packs. The shorter end is usually the one with the broader terminal, and this is the positive pole, but not always. Sometimes it can be confusing which way to insert your battery pack into your device ...
