The video is correct in regards to the Cathode/Anode labeling. When discharging, the negative terminal is the anode because the electron leaves from there. When charging, the electron is going into the negative terminal. The anode and cathode can be either the negative or positive terminal in a device, but it depends on the situation. The exact definition of which terminal is the cathode or anode doesn't have to due with polarity, but rather with the chemistry redox reaction; i.e., which terminal is the oxidizing component, and which component is the reducing component. You'll have to read up on redox reactions to totally understand this. Most often it probably works like this though: if the electro-chemical device is producing electricity, the anode is negative, and if it's consuming electricity (even passively like a diode), the anode is positive. Note that with motors, this isn't an issue because chemistry isn't involved.

Congratulations! The video is excellent.

Very nicely explained.. Appreciate it..

Thanks this helped immensely😊💞

does PbSO4 always reversible reaction during charging? can it be sperated as Pb and SO4?

In some other videos cathode is spongy lead (pure lead) Anode is lead peroxide...pl clarify

I don't know how I should I thank you 🔥🔥👍👍

After a long time my concept clear to see this video thanks a lot

Thanks for your valid information ma'am ❤

Nice lecture Mam, thanks.

Good explanation..

What makes the H2SO4 split in the first place?

Excellent explanation, thanks for the video

Er the first sentence: "The most widely used battery in electrical vehicles is the lead acid battery" - no, not in 2022 or for many years. It is the most widely used in *petrol/diesel* vehicles due to its power performance characteristics, specifically suitability to supply high currents for short periods to turn the engine over and then charge slowly once the combustion engine is working.

Mantap sis

Where is the separater in charging prosses and dis charing and what is it working

Thanks 🎉❤

Super ma'am

Pb02 is Anode when charge condition and Pb as cathode

Thank you mame

02:40 how does these electrons move to the Anode AGAINST the negative terminal of the charger?

Must be really bright in India, because she gave info so fast.

Mam help me i conused In lead acid battery Anode Is positive or negative.? some vide channel say Anode is positive but, more video channel (including your video) say Anode is negative.! Which one is correct.? Plz help me.!

volt?

Voltage is pressure and Tesla said electrons do no exist. Can we confirm the chemistry? If so how? Regards DC

😀👍👍👍

Clarify please. Why your illustration during charging has the Positive as the anode.

Why does that reaction happen simply because a load is connected or a circuit completed?

Nice video

Ahhhh I hate chemistry... but your way of teaching is nice. I am just too dumb.

MAKE CORRECTION, ANODE IS LEAD OXIDE AND CATHODE IS LEAD SPOUNGE

Good..! But don't you think anode is the positive terminal...??

Isn't Hydrogen gas produced in the reaction!??

You explain the process of discharging and charging a lead-acid battery well enough, but you have one detail wrong. During the charging process, water dissociates into positive hydrogen ions and negative oxygen ions. In practice, the negative ion of oxygen is not stable in an acidic environment such as a solution of sulfuric acid, because it is too basic in nature, so it would immediately be united by the present positive hydrogen ions into water. Which returns the reaction step to the beginning. The process is different, but the essence is actually the same. When charging the battery, at the cathode, lead sulfate is reduced by the arrival of electrons from the external negative terminal of the current source, into elemental lead, during which the sulfate anion moves from the electrode to the electrolyte. Due to the increase in the concentration of negative sulfate ions, the electrolyte has a strong tendency to generate positive ions, so water is oxidized at the anode to oxygen and positive hydrogen ions that increase the activity of the acid in the electrolyte, and the oxygen binds to the lead released from the lead sulfate salt, forming PbO2. At the anode, two electrochemical reactions take place in parallel, the oxidation of lead sulfate to a lead positive ion and a sulfate radical that strongly takes electrons from hydrogen from water molecules, building positive hydrogen ions and nascent oxygen, another water molecule is also oxidized by the positive lead ion taking electrons from the molecule water and generate positive hydrogen ions, where it binds to two nascent oxygen atoms and builds PbO2.

this is NOT an explanation of the working principle. It is simply an analysis of the chemical reaction involved. In order for it to be a working principle video, the specifics of the reactions should have been abstracted, and the importance of the separator should have been explained. It should also have been mentioned that H2SO4 completely dissolves into SO4(2-) + 2H(+) REGARDLESS of whether or not it is discharging. This is of vital importance to know what the battery is doing when it is neither charging nor discharging. Not a good explanation. People watching this will simply copy the chemical reaction without understanding the actual principle of how a battery works.

@0:54 anode (-) cathode (+) pl correct it

PbO2 is anode

lead cannot accept more electricity or cannot stay long, much better is the cooper and the carbon using are needs active ,,long life of battery extra volts given and more force

In Lead Acid Battery, PbO2 is Anode and Pb is Cathode

?

Anode is Lead peroxide and cathode is spong lead

kindly don’t give false information. anode is lead peroxide cathode is sponge lead
