New research on battery self discharge

[DMC-81]

I saw this article on Tesla funded research that found a cause of self discharge of lithium ion batteries.

Seems like a relatively quick win to substitute the tape for something else that doesn't degrade.

It's interesting such a common compound might foul things up in a way no one was thinking. PET plastics are used almost interchangeably with glass for non-reactivity.

TLDR: “In commercial battery cells, there is tape — like Scotch tape — that holds the electrodes together, and there is a chemical decomposition of this tape, which creates a molecule that leads to the self-discharge.”

Higher temperatures accelerate this decomposition, whose products shuttle back and forth in the cell, neutralizing it’s stored charge. No mention of how easy it will be to substitute.

We: Doctor, it hurts my battery when I do this!
Doctor (of materials): Don’t do that.

This will make for a nice change trying to explain battery advancements to my friends and family.

From:
"Extensive research into different compounds has been going on for years, and you can make both good and bad arguments for the inclusion of various elements like cobalt and nickel depending on your use case..."

To:
"The scotch tape was janking up the batteries."

4680 is evenly divisible by 8, so... yes, that can work.

4680 ÷ 8 = 585
