This technique allows us to see all these neat things that are happening in lithium batteries. It explains a lot of questions we had about how and where theses dendrites form. Neat things which we will not show or explain to you over the course of this video, but you can take our word for it that these things are really neat. Congratulations, this video is disappointment incarnate. You've literally made a video that toots your own horn for a job well done while not being at all informative or educational.
Very nice video but it's crazy that no one has done this before! All the years we've been trying to improve lithium batteries... The idea of observing and looking at a problem to get as much information as possible is common sense, a lot of prototypes are made with cut-outs or transparent sections for the same reason.
Its great, but i want to ask about the tools that you used to evaluate the dendrites growth. are you assembled the tools by your self or buying for it ? May i know the information about the equipment to analyze the dendrites growth ? I hope you can answer my question Thanks for your attention
The video is disappointing in that they don't mention what the affects are. Do the dendrites form when they are charged and depleted too fast, they won't say. It only says they can watch them. Is this a trade secret?
All sorts of things can encourage or discourage dendrite growth. Heat, chemical properties, cell layout or design, speed of charge or discharge, temperature.
I am no battery expert, but the rate of discharge/charge, chemical makeup, the structure of the cell, and temperature of the battery are all things that can promote or discourage dendrite growth.
Electrical engineering and Chemistry, though Materials Science and Chemical Engineering may also be relevant. Source: my university had a battery lab and a battery research program targeting post-graduate education.
One thing is for sure: you wouldn't bother putting a battery in your car big enough to drive from NYC to Denver. Why would anyone pay the expense, weight, safety penalty and slow charge time of having a battery that big?
Battery technology has been steadily improving 5-8% per year. So while it seems slow, it has really been growing exponentially. All this is the culmination of improvements. Not massive breakthroughs.

Wow, I can't wait for these very real realities to become a reality!

It's great to be a Michigan wolverine.

Awesome.
What are major factor for dendrites & how to control it?? Please explain in short ( at least).

What sort of engineering would this fall under. Chemical engineering?

Battery research is done by mechanical, chemical, materials science engineering typically, and also chemistry.
are we ever going to go electrostatic?

add a dash of silica
I wanna take my electric skateboard from los angeles to san diego :)
So Li-ion battery cells get cancer... and we need to in effect cure this before we can advance with them. I know, very non technical, but....
Clearly no one from Michigan Engineering works at Samsung.....Samsung take note(heh).

Running gag. We are almost there... Now we made it, the future battery... Not
