How batteries work - Adam Jacobson

View full lesson: ed.ted.com/lessons/why-batteri...
Batteries are a triumph of science-they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.
Lesson by Adam Jacobson, animation by FOX Animation Domination High-Def.

Ted-ed explains batteries clearer than my actual teacher. Keep up the good work guys!

[@ShangDi_became_Jesus]

stop using teachers as the standards...they are just people that took courses to convey what they learned....ted has scientists that play with this stuff all day long, thats who you always learn from ....the ones obsessed wtih their craft.

I modified mine to bleep :D and it was more complicated than your brains physical structure.

Great video. I'd love to learn more about the process of the recharging of the battery.

I’m not sure but I know you can magnetize a needle by striking another metal against it around 50 times.

[@BukuiZhao]

So most of the zinc in the battery has finished oxidizing. But I think you have rechargeable battery so you can reverse that process.

[@LordGrimmie]

Gorgeous animation!

[@jericojopio1713]

It's really amazing that Alessandro Volta had already known about the presence of animal electricity for many centuries even before the scientists after his time conducted experiments on electrical impulses in the human body. As a sidenote, the word "voltage" came from his own surname Volta. I'm probably not sure, but there might be other historical sources pointing out to Alessandro Volta's experiments on early batteries.

[@BoogsterSU2]

Still waiting for graphene technology to kick in.

[@RoScFan]

Boogster Su That's not a battery. It's a capacitor that keeps the charge for longer than normal capacitors. It's like a supercapacitor. Which is good. It's amazing we still use Volta's 300 years principle today. JUst replacing the substances doesn't mean much when the principle is the same. It's like light bulbs... no matter what improvements you make to an incandescent light bulbs it doesn't matter if it's still incandescent. What is really progress is switching from incandescence to LEDs. Similarly batteries need a makeover. Glad to see the potential in graphene.

[@gabbonoo]

Boogster Su I think you wana say: "waiting for everything to run on field charge"

[@Bryan-th6rc]

+Boogster Su Yeah, screw paying 1000 dollars for headhpones when graphene perfectly reproduces sound.

[@vanessavlogs3185]

[@MrRobbPhoenix]

Very nice animations/Music! Loved it!

[@digitalfootballer9032]

Here's another penny's worth of information for free. What us Americans call "flashlights" (British "torch") got their name because of early batteries. In the late 19th century, cops carried flashlights on their beat at night. Since batteries back then did not last long, the officers would simply "flash" the light into dark alleys on patrol to save on the battery. Hence the name flash-light. They were also very large and cumbersome devices in those days.

[@stephensnell1379]

The modern torch is way more efficient especially for example the torch I have got is an L.E.D. type and there are 9 L.E.D. diodes inside it and it's powered by 3 AAA batteries which last for over 12 months before they need changing I change the batteries when there is hardly any light coming from the torch

[@abhijeetingawale9213]

the animation is really great and easy to understand

[@rheyse2721]

how does the electricity from the outlet make the electrons flow back into the metal?

[@chaseramos4865]

an outlet is able to push electrons out into the battery which pushes used electrons back to where they came from. Then once the outlet puts the electrons back where they were originally in the battery you can use it again.

[@russellbond1232]

[@swarajsk3560]

People curse technology when it don't work but they are triumphs of science and human intellect which we rarely praise.

[@dmarkle1111]

Hi! Electrical engineer here. WATCH OUT for this video, because it makes statements which are demonstrably wrong (like the statement that batteries store charge), and it has VERY misleading animations. Batteries DO NOT "store charge". They store ENERGY. The animation also shows the battery "sending" electrons through the wire that aren't already there. I'm not being a stickler here. If you want to show someone how something works, don't be wrong. Watch out for bad "explainers" on the Internet, people.

Viktor6665 you probably have a bunch of apps running in the background, and other power draining stuff (bluetooth, wifi, outof-range of cell towers). And/or you need a better charger (one that outputs more amps). Could be lots of reasons.

[@videogyar2]
