Batteries Come in All Shapes & Sizes, But Each One Sucks in Its Own Way (Part 1 of 3)

by Moin Uddin Ahmed Tipu

Batteries have been around for 2000 years, but still have a lot of room for improvement. Why aren’t modern batteries better?

Part 2 of 3 –
Part 3 of 3 – Coming next Thursday!

Why Does Cold Weather Drain Your Phone Battery?

“Lithium-ion batteries, the commonplace rechargeables that power much of our modern lives and live inside almost every cellphone, discharge electric current as individual lithium ions move through solution from one end of the battery (the anode) to the other end (the cathode). ”

Effect Of Temperature On The Aging Rate Of Li Ion Battery Operating Above Room Temperature

“Temperature is known to have a significant impact on the performance, safety, and cycle lifetime of lithium-ion batteries (LiB). However, the comprehensive effects of temperature on the cyclic aging rate of LiB have yet to be found.”

Solid electrolytes open doors to solid-state batteries

“Japanese scientists have synthesized two crystal materials that show great promise as solid electrolytes. All-solid-state batteries built using the solid electrolytes exhibit excellent properties, including high power and high energy densities, and could be used in long-distance electric vehicles.”

I agree Michigan is cold.

In a CRT, the cathode is what gives off the electrons (negative), and the anode is what sucks them up (positive), thus creating a beam of electrons that travels from the cathode to the anode. Hence the name Cathode Ray Tube. Are you sure you didn't mix up cathode and anode in your battery description here?

mmmm, tasty brain food! ( ͡° ͜ʖ ͡°) ( ͡⊙ ͜ʖ ͡⊙) ( ͡◉ ͜ʖ ͡◉)

lol continously shocking yourself due to the excitement of a new discovery. The excitement, the enthusiasm to know, to discover the UNKNOWN. Man's curiosity has no bounds!

Just wanna say that I love watching these videos. Trace is so smart and love the way he explains thing. Also he’s super cute so it all works out well.

Batteries can't be better. We use chemicals to store energy in the form of bonds and high energy electrons. This is on the atomic level. Not on the levels we see in batteries. It's just so much more energy dense. It's akin to the relationship between storing on the subatomic level (nuclear) to the atomic level (chemical). It's just multitudes less dense.

Did Simon from various channels (Today I Found Out) use these as a reference for a recent video?

MT SB April 30, 2018 - 11:33 PM

I did not get the size thing…I mean there are way different specs for a small and a big battery. And yeah you could increase the size to power ratio but that's just development in both the sizes, and that does make the battery unsafe, like the Note 7 one.

It's funny that Ben Franklin could be a hero to you. Or Washington or Lincoln, etc…
I don't think these people are heroes to anyone outside the usa. I could be wrong, this is just my personal observation.

Anode is the positive end and the Cathode is the negative end. Electricity flows from the Cathode to the Anode.

thanks for the crash course.. Now I have some knowledge to brag about

Mahesh Maheshindersingh May 28, 2018 - 1:04 PM

Bro please add subtitles to the video

Mahesh Maheshindersingh May 28, 2018 - 1:12 PM

This was a boring video bro , the only boring video on this channel , although the content was useful

I recently heard a slightly different origin of the modern use of "battery", which sounds more likely: It's to do with cannons. You have a "battery" of voltaic cells just like you would have a "battery" of cannons. Also, when you load the cannons with gun powder, you "charge" them. Hence why you "charge" a "battery" of voltaic cells with electricity.

2:12 FALSE! Anode is positive, and Kathode is negative! You've mistaken them with Anions and Kathions.

Lots of mistakes, hence, bad video☹

As a chemist, I enjoy watching these types of videos. Unfortunately the writers and producers of these types of popular science shows need to bring their discussions down to a level easily understood by all education levels. This often leads to inaccuracies and omissions in the presentations. I find it more fun as a professional scientist to watch these shows and to pick out everything that is inaccurate or incomplete. In fact, I used to assign my freshman and sophomore chemistry students the task of reviewing selected videos and listing all the inaccuracies and errors.Then again the few YouTubes out there that do provide high accuracy and completeness tend to be a bit dry and boring to the masses.

For the haters out there, please do not malign the presenters and hosts. Most of them are excellent speakers (far better than me) and are usually not experts in the subject matter. Trace happens to be one of my favorites as he is very upbeat and passionate about the material and he is very easy to listen to. It's the writers and editors who need to be more thorough in their research. Often times those mistakes and omissions are quite embarrassing and I have noted little attempts by these science channels to correct errors.

Yes this video has several glaring mistakes. In addition, some of the comments provide less than accurate information and corrections. One of the best lesions to get out of these things is the ability to think critically and research things for yourself using more authoritative sources.

I did find some disappointment with the video as it did not even mention oxidation/reduction reactions and half-cells which are the key to understanding batteries. Perhaps Trace will do that in a future video after he insists that his material first be reviewed and edited by a chemist. :-)

I came here just to see the comments…

been so long since I've seen trace tbh

I do not have the crystal ball, but from what the people of visual politik say, the Lithium deposits of Argentina can balance our difficult public accounts and Argentina can be due to its great competitive advantage the Supermarket of the World, in addition to the Vaca Muerta Oil What displeases me is that the media of my country and all politicians do not communicate this issue well, there is no good intention to be able to speak clearly without ambiguity about the correct course towards a liberalism like New Zealand, Chile with only 4% of unemployment without inflation and a balanced economy, such as Australia or Canada, but to make these transformations you must clearly communicate what the direction is, and I do not understand the bad intentions of the media that do not transmit this well and also absolutely all politicians neither do they transmit it or sell the road to the common good of one of the countries of the world with greater wealth. natural, look at the potential of Argentina with Lithium

In actuality a boring lecture on how batteries work, NOT an entertaining rant about why the hell we still have C batteries.

I HOPE the future will NOT be battery-powered.

The Baghdad battery is weak evidence
