Thread: The batteries of the future, weightless, and invisible.

One thing that I either didn’t read is what is the expected life span of the structural battery? If there is one, and I assume there is, how do you replace a structural battery?

Yeah, total BS I reckon.
But in this era of engineered throw-away-and-buy-a-new-one mentality ... this is how you replace a structural battery!

how else are they going to make money?

Short term thinking folks will think to themselves ... yeah .. fantastic more range .. blah blah .. then it comes to resale time, and they can't even get a dollar for their $100K vehicle (say) 5 years later .. demand for new models will collapse.

Its battery pack will be integrated into the chassis so that it provides mechanical support in addition to energy, a design that Musk claimed will reduce the car’s weight by 10 percent and improve its mileage by even more. He hailed Tesla’s structural battery as a “revolution” in engineering—but for some battery researchers, Musk’s future looked a lot like the past.

That's a fascinating article. It's going to revolutionize design. The structure is the battery.
Maybe the structural battery will not have a defined life, but will just keep operating and never need replacing.

Bollocks...

Ask yourself where the energy comes from then.... remember the rules - Energy is neither created or destroyed - it changes form.

New ways of thinking are usually met with scepticism until they are proven to work.
If the vehicle is the battery and lithium ions are flowing around the structure to generate energy then what's to stop them just continuing to flow around and around endlessly? They're not being lost, but just moving.
A pumped hydro plant does the same thing to generate energy by moving water up and down endlessly, so it's not a new idea.

Interesting.

WHAT? . Thanks for the best laugh I’ve had today!!!!

Firstly - why would the “Ions” be lithium? And why would it be Ions? Not electrons?


Batteries convert chemical to electrical - there are losses.

Pumped hydro has HUGE losses - it’s economic benefit is to use off peak demand power from outside sources to replenish the upper holding tank.

Neither system is lossless and the battery must consume from one surface or another - it’s how batteries work. Even the best rechargeable batteries have finite cycle life.
