its a shame? there were no half equations =[ it would have made this a reputable video.

I agree, I wish they would show what was happening on the atomic level. I also would like them to go in-depth and explain why they chose the elements they did for the? battery (Al, Cu, C, LiO) and maybe how the permeable filter works. Otherwise it did a very nice job of summing up the voltaic cell.

[PSK] @skulman1194 @digadogup Thank you for your comments. Its always hard to find the balance between “easy to understand for all” and “all information? in one”. We will take your suggestions into account when producing our next videos. As a first step I added a link in the video description with for more in depth info about battery materials. Maybe this is useful for you.

i didnt understand how electric current is created if there is no any conventional electrons? disassembled and moving through? why + ions are moving instead of – ?

The video depicts the elctrochemical side of a lithium ion battery. It shows electrodes, separator + electrolyte. The latter transports lithium ions from one electrode to the other. The separator? separates both electrodes and prevents electrons from taking the same way as the lithium ions. The electrons take the “outer” way from one electrode to the other, i. e. they form the electric current that is used to drive an electrical appliance attached via electric cables.

Ummm… I do believe you mixed up anode and cathode, anode is the positive and cathode is? the negative. A good way to remember this is with the saying “Cats are black and Ants are red”

No, it is correct, compare with the Wikipedia article on? cathode: “Cathode polarity is not always negative. Although positively charged cations always move towards the cathode (hence their name) and negatively charged anions move away from it, cathode polarity depends on the device type, and can even vary according to the operating mode. In a device which consumes power, the cathode is negative, and in a device which provides power, the cathode is positive.”
