Elon Musk: Boeing 787 battery fundamentally unsafe

By: ZACH ROSENBERG WASHINGTON DC

The lithium ion batteries installed on the Boeing 787 are inherently unsafe, says Elon Musk, founder of SpaceX and owner of electric car maker Tesla.

"Unfortunately, the pack architecture supplied to Boeing is inherently unsafe," writes Musk in an email to Flightglobal.

"Large cells without enough space between them to isolate against the cell-to-cell thermal domino effect means it is simply a matter of time before there are more incidents of this nature," he adds.

Both Boeing and Tesla use batteries fueled by lithium cobalt oxide, which is among the most energy-dense and flammable chemistries of lithium-ion batteries on the market. While Boeing elected to use a battery with a grouping of eight large cells, Tesla's batteries contain thousands of smaller cells that are independently separated to prevent fire in a single cell from harming the surrounding ones.

"Moreover, when thermal runaway occurs with a big cell, a proportionately larger amount of energy is released and it is very difficult to prevent that energy from then heating up the neighboring cells and causing a domino effect that results in the entire pack catching fire," says Musk.

3. You'd Think That if the "Thousands of Little Cells" Design was Implemented for a Car's Safety

That perhaps Boeing's engineers might have talked to Tesla about batteries since they're using the same kind of Li-Ion chemical formula. It's apparent that it must not be a complete trade secret since the basics of the Tesla battery were detailed in the linked-to article.

4. A few years ago, it was laptops and cell phones...

...that had batteries that caught fire and exploded like roman candles.

Now it's airliner batteries that are doing this.

Wonderful.

5. Elon Musk, the founder of Pay-Pal owns Tesla?

Well, I guess all those pennies per transaction really added up for him.............

I ain't mad at him.

6. Musk really has the right vision for the future

You should read his wikipedia entry and watch his interview on Jon Stewart.

...
Musk then considered three areas he wanted to get into that were "important problems that would most affect the future of humanity", as he said later, "One was the Internet, one was clean energy, and one was space".
