Research lab accidentally creates longer lasting Li-Ion battery

Scientists at Tsinghua University, Beijing, and the Massachusetts Institute of Technology, Boston have been working on techniques to extend the working life of Li-ion batteries. The scientists were working methodically on making the anodes of the batteries more durable, as the decay of the anode material is a major cause of the drop off in Li-ion battery life after a few hundred charge cycles. In the course of their carefully timed experimental process one batch of anodes were left under chemical treatment for several hours more than they should have been, by accident. Instead of throwing away the forgotten batch, the scientists decided to test them and the results were great – an anode 4x more durable than the current best available technology.

 

 

Hopefully we can get some really good batteries now rather than ones that can barely hold a charge after only a few months.

I love accidents! They're so good sometimes.

 

 

Except children, those aren't good accidents.

I know man. Imagine the chick you screwed last night drunk coming to your house after some time and suddenly you're a fucking dad. Damn condom accidents... Hate them  /s

[Vitalius]

Are you serious?

Just cook them longer?

That's not the first thing they tried? 

WTF scientists? Do you even bake?

5:40 in the morning and I read that as "and suddenly you're fucking a dad" o________________O'

Why not cook them at twice the temperature for half the time?! That works, right?

Instructions unclear. Built better battery. It was supposed to be a desk from IKEA

What if people had common sense in general?

This is why us clumsy people will one day save the world.

We need more happy accidents.

Like penicillin, microwaves, etc

I'd guess that this was already known by manufacturers, and that marketed batteries have been designed to last a limited duration, as an example of forced obsolescence. I think this probably isn't news to battery manufacturers.

Ok this is a miss conception. Lithium-ion/poly batteries varies greatly between manufactures. You can see it like IPS panels. They separate in a large number of sub groups of models where they all have their ups and downs. It just doesn't have any marketing related to them, so they are nothing more then models being used to identify them and specs sheets.

That is why you have Lithium-ion/poly batteries, despite the same capacity, same specs system (say laptop), one will last longer than another. This is also why, some degrade rapidly within 1 year and half to 2 years, while others can remain 80% of it's charge capacity after 4 years. This is also why some are sensitive to heat, and others aren't really affected by it. All these inconsistency has to do with the different models of Lithium-ion/poly batteries.

I am most certain that if any other manufacture tries this, it won't end well. It is something that has been discovered with that specific lithium-ion battery.

No. Battery competition is super high. Assuming they did what you are saying, you'll have the small guy that tries to grow, will make it happen, and now has the monopoly on batteries.

Huh. Cool.

You'd think in an industry as potentially toxic to the environment as batteries, there'd be some standardization & regulation. Guess not.

They are some regulations in how to package and store the battery, and regulations related to avoid the battery to explode, including on its charging circuit. But, to my knowledge, not on production (beside safety), or minimum specs.

But before that happens, they get swallowed or subdued by the big fish. And then they put the new tech behind a paywall to monetize the F out of it.

1- If you have such technology, like the magic cure for cancer, you can make more money as a company, then accepting being bought by a large company.

2- Not all companies are public, and therefore can't be bought the next day.

3- Usually companies have the Poison Pill clause (yes that is the name) in the company share acquiring agreement. The Poison Pill clause, usually states something like if you buy more than a certain percentage of shares of the company, the cost of owning a share is increases for every share substantially high, making it impossible to even a large company to acquire them on the back, without agreement of the president/CEO/current shareholders (depending on how the company is structured).

Still remember during engineering class, the teacher took out 2 transparent plastic panels, and tightened with a clamp. He then swing a hammer at it, one of them broke immediately and the other no matter how hard he swings, the things just doesn't break.  The one that didn't break was also discovered by accident.

Great minds think alike!

I find it amusing that some of the most world-changing scientific breakthroughs were accidents. Makes me wonder if scientists should think more laterally and/or be more absent-minded at work. Who knows, some physicist might just accidentally create the Theory of Everything tomorrow.

Also the work of some divine power behind these "accidents".

[D4RK]

now i see why linus got taran and dennis into LMG, he is hoping for good accidents to happen

[Doobeedoo]

Aha. But when will we see something entirely new already. A type of battery that will last for days on constant usage and charge quickly.
