Featured Seems Draining your Lithium Ion Battery is really bad

The transition to Sodium-Ion is already underway for Seagull... The vehicle was specifically designed for Sodium-ion and the first ones were LFP in order to meet difficult deadlines, but most of that is already behind them now.

 

We're both right... One of us is looking forward towards what is going to happen next... The other one is looking backwards and trying to argue that the success of the past won't allow the future to happen. It's a progressive view versus a turn back the clock anti-modernist view.

Or even better stated is this article about Tesla: "...as Tesla remains stagnant, other manufacturers are racing ahead. BYD, Hyundai, and General Motors are launching more affordable models with advanced technology and aggressive marketing strategies, winning over many who once trusted Tesla. And of course, this massive loss of loyalty is not going unnoticed at the American giant. It almost feels like a seasoned senior is being overtaken by a newly recruited rookie."

When it comes to how Tesla finances things it makes them particularly vulnerable... They're the opposite of what Apple has done by sitting on a massive pile of cash, as well as getting their parts and products exempt from the trade war. Not even Elon trying to be best friends with Trump is putting him in a position as favorable as how Apple is managing its business.

 

Well that was the rumor that some would come with a smaller sodium ion battery in 2022. Its 2025, and I have not heard mention that they have sold a single one. I'm sure they have some running as test mules, but maybe it didn't perform as expected.

Try again. Some small manufacturers have put out a token number. BYD and CATL are producing sodium ion for fixed storage where weight and size are less important. Let me know when your mirical happens, until then don't name call or pretend those of us that don't have your magic crystal ball are racists against the Chinese. Why do you hate Texas and Tesla so much?

 

If I were his ambassador, I would say, & rightly so, it's because he's a never Trumper, whether Trump does good or not. An that's ok as we're a multi party nation.

In #16 I specifically pared back the verbiage to the two contradictory claims on current fact that you and austingreen had made, as a way of maybe cutting through some of the sloganeering.

That was the idea anyway.

 

Why did scientists do this research only now?
I first discovered a swollen battery on my mobile phone about twenty years ago.


And yes, the process of battery combustion in a phone is less effective than in a car.

 

Is it OK if we wear out our current inventory of batteries? <GRINS>

BYD started building a sodium ion plant a year ago. CATL started this year.

CATL has mixed chemistry battery packs that could have Na-ion with Li-ion. Don't know which EV models use them. Otherwise, I'm only finding two EVs that use Na-ion. They became available last year and are both city cars. These are iQ to Spark sized with a top speed of 63mph. The Na-ion trims have noticeably shorter range than even the LFP trims; one is 93 miles on NEDC.

I'm not finding production model specs for the other one.

 

I know the chemistry varies, but I have had some success with getting lithium cells to start charging by giving them a shock charge of over 30 volts. It's important to limit the current so that it won't runaway and overheat. I think it may have something to do with burning out the dendrite shorts.

 

That almost sounds like running a compressed air hose into an empty gas tank then throwing a match in it - to "clear it out". It may work, or it may go very wrong.

Hummmm, have you considered using a charged, BAC (Big As Capacitor)? No risk of a thermal runaway and minimize (bur not eliminate) damage to the separator.

Have you done a charge-discharge of an identical new or working cell versus one you have regenerated?

The reason I ask is the literature blames the SEI layer for capturing the lithium ions leading to a permanent loss of capacity. There are reports that the cathode and anode may have irreversible chemical changes that lockup the ions.

For historical reasons, the old NiCD batteries did generate dendrites and I understand it was common practice on aircraft carriers to "burn them out."
