China develops fast-charging aluminum-graphene battery
Xinhua, December 24, 2017

A team of researchers from Zhejiang University have developed a new type of aluminum-graphene battery that can be charged in seconds, instead of hours.

The team, led by professor Gao Chao, from Department of Polymer Science and Engineering of Zhejiang University, designed a battery using graphene films as anode and metallic aluminum as cathode.

The battery could work well after quarter-million cycles and can be fully charged in seconds.

Experiments show that the battery retains 91 percent of its original capacity after 250,000 recharges, surpassing all the previous batteries in terms of cycle life.

In quick charge mode, the battery can be fully charged in 1.1 seconds, according to Gao. The finding was detailed in a paper recently published in Science Advances.

The assembled battery also works well in temperatures range of minus 40 to 120 degrees Celsius. It can be folded, and does not explode when exposed to fire.

However, the aluminum-ion battery cannot compete with commonly-used Li-ion batteries in terms of energy density, or the amount of power you can store in a battery in relation to the size, according to Gao.

"It is still costly to make such battery. Commercial production of the battery can only be possible until we can find cheaper electrolyte," Gao said.

I hear these news almost every few months. But the final silver bullet has never appeared. What these articles fail to tell is that such tests usually happen in very idealized laboratory conditions and have not been able to be put into final consumer product.

This is not the case only with China. But with everyone.

These two facts alone make the battery useless.

There is low energy density and it is expensive.

Leave alone the fact that it will face many unknown challenges in real world commercialization.

Super Fast charge can make up for low density. For most urban commuters, a daily mileage is 80km-140km. If it need just 1min to charge up full capacity and the charger is plug into the grid. It can be a very convenient task.

I agree. It could be useful for some cases.

To determine that we will need to look closely at data.

Don't also forget the cost and the problems that industrial production present separate from the lab scale.

In fact even better it can be used first in buses which have predictable routes and they have to stop at some stops.

I like how sour power tries to discredit these efforts with some effortless hyperobolic claim of lacking novelity any nobody can pull out of his *** and accusations to omit critical deficiencies and implications for commercialization of the technology only to quote the the last third of the article all over again where it explicitely points them out and screech a whole lot SEE JUST AS I TOLD YOU EXPOSED!!! . You just can't win, even if you do everything right.

Leave alone that utterly worthless grasping for straws comment that the new technology may "face many unknown challenges in real world commercialization". Well thanks for pointing it out captain obvious but Im pretty sure they just assumed their audience isn't completely retarded and detached from reality and it just wasn't worth to waste estate and even go into something as speculative and vague as that when they just told you it isn't even considerable to be put into the final consumer product yet. You should have known that this is the norm though if you actually would have read such articles every few months.

Listen mister "enlightened", most of the people who post and read such articles miss all the caveats that are associated with this. They don't know about all the real world challenges when translating such things into real life scenarios apart from heavily idealized conditions of the lab.

If you know all that good for you.

All this just to show your superiority complex, wow. Repetition or not, he made a point and it is valid. Now STFU and mind your business.

The intellectual density is so low that there is space only for repetitive strawman's argument.

Especially the part regarding commercialization reflects poor Indian mentality.

You know what it suggests? It suggests that Indians are smart and practical, hence they do not waste energy on trying new ways but always take the old, safe, well-worn road.

To them, never trying is preferable to the potentiality of failing.

This explains India's present conditions. That's strategically good. The downside is they litter every thread with similar mediocre arguments.

 

[qwerrty]

he's not wrong. supa battery breakthrough news popping up every few weeks since i know how to use the internet and so far all the batteries on the market still suck ***

1. Umm... Your comment is pretty much the definition of a strawman argument.
2. So you are extending one Indian's comment to comment on "Indian mentality."
3. Your thesis is totally wrong. I am not downplaying experimentation or attempts. What I am saying is that many people take such reports as proof that such battery is coming soon. Infact most people don't even read the article, just the headline, which is particularly misleading, since it mentions nothing about the various challenges faced for commercialization of such technology.
4. If you already understand this important caveat, than my comment was not for you.

 

[TaiShang]

Stop enlightening and educating people on the grounds that they may not be reading (or not understanding) what they have just seen.

Is it this Indian mentality (helping people understand) that made you a call center superpower but not an innovation superpower?

Does the main idea of the OP involve the question whether it can be commercialized or not? And hasn't the OP already referred to that question at the end as a side note?

What is with this linear and uncreative Indian mentality that attempts to prove us what we already know because it is simply too obvious?

What is your contribution here other than pestering?

 

[DoTell]

Wow, i expected this intellectual reply.

Well, he let you have it by giving you a reason after you simply told him to”STFU”. So his reply is indeed much more “intellectual” than yours. The fact that you give but can’t take and yet pretend that you possess some civility shows that you are nothing but a low quality “intellectual”, a. k. a. a fool
