Lithium-ion batteries!! How They Work & Why They Die

This video was sent in to us by Teddy! Teddy says:

I am building a series of videos that dive deep into the details
of how electronics such as our smartphones work. My goal is to assist in
inspiring students to become scientists and engineers. I just finished a
very thoroughly animated episode on how Lithium-ion smartphone batteries
work, and I would greatly appreciate if you could show it on the Adafruit
Blog! I feel students and hobbyists would greatly appreciate learning about
how batteries work in detail.

This video and more can be found on the Branch Education Youtube channel:

How many lithium-ion [Li-ion] batteries have you used today? Probably more
than you think! Lithium-ion batteries are practically everywhere, but how
do they work? Why are they rechargeable? And why do they die earlier and
earlier in the day the more you use them? This episode will go deep into
detail and explore the lithium-ion battery in your smartphone and answer
each of these questions.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
