Thread for new battery breakthrough PR releases

I bet it will end in the same old story like graphene where after years of trying they just can't mass produce it on of a feasible level.
I bet you could blend pee with lithium batteries and increase capacity by x3 times but then after years of research they find they can't reproduce pee on a feasibly commercial level and it's too ridiculous to ask millions of people to pee in a single factory and that pee kits aren't viable because the pee has to be fresh and the blend method for adding it to the lithium batteries is a closely guarded secret.

They are trying it with fertilizer..... :twisted:
http://www.scientificamerican.com/article/human-urine-is-an-effective-fertilizer/

Snip......
"It is totally possible to use human urine as a fertilizer instead of industrial fertilizer," says Heinonen-Tanski, whose research group has also used urine to cultivate cucumbers, cabbage and tomatoes. Recycling urine as fertilizer could not only make agriculture and wastewater treatment more sustainable in industrialized countries, the researchers say, but also bolster food production and improve sanitation in developing countries.

Nothing new there.
Same old carbon lithium technology just little improved.

I can not find any information of the wh/kg . so i guess its the same shit like we have currently aviable.
 
This may be a real game changer in battery powered vehicles!
They have tested these batteries and have proven them to be charged and discharged in 12 minutes, charged to the fullest and discharged to the minimum and require no cooling. With practically no internal resistance and no fears of combustion after damaging the battery, a real advance in quality. Another advantage is that they will be packaged in the style of Panasonic computer batteries 18650.
This might greatly simplify the battery management system, as well.
This would make it possible to use a smaller battery pack, with more frequent charges.
Power Japan Plus is now offering license agreements.
Maybe Tesla's Elon Musk is considering this battery?


 
I'll wait until it hits mass production before believing. There has been too many "break through" in battery technology, but very few, if any, have come to fruition.

I don't get these news line. Why not wait until they say we have the product at certain price RIGHT NOW before releasing the news story. Maybe it is a way to get money... Both for the media and the company who is making the wild claims.

..ahh !... If only I had a dollar for every time we have heard that !
Having a working new technology cell is one thing, but it's a long way from a proven commercial cell coming to the market.
Personally, I don't see the 18650 format being an advantage for EV use.
I won't be holding my breath for this.

PS. There is a thread specificly for this type of propaganda .
 
I've been following this since it broke.

I'm currently trying to get any functional example cell. Coin cell or whatever, anything that shows you can even create a potential with carbon for both anode and cathode.

I want there to be something to it badly. 99% of the time these types of videos are just BS, but my fingers are crossed that it turns out to be real. :)
 
will wait on taobao.
China was first who imported japan panasonics and sell worldwide.

Lifepo4 is the cheapest battery on the world today in the long run?

In stationary applications where weight is not a factor, maybe supercaps are competitive.

So SLA offgrid systems is history?

VRLA or Pb/acid (I really don't like the term SLA) should be history. In terms of cycle life alone it fails against other chemistries.

Yeah the tech has been posted on this thread now and then, but that link is a new but same old stuff. Should of posted the Youtube video below as its more exciting, seems all Israel based, hopefully its all true or I demand their lab be rained on with katyusha rockets, that should get them moving!

Recently in the news, Alcoa and Phinergy are producing Al-Air primary battery that can be used to extend electric vehicle's range by up to 1000 miles

http://www.guideautoweb.com/en/articles/25459/a_long-range_electric_battery_pack_made_in_canada/

Recharge is simple as replacing the Aluminum in the battery. Currently it might be more expensive per mile, but it should eventually get down to a low enough level lower than petrol.

That being said, I would like to see a home charger which will reverse the reaction to reclaim the aluminum so we can "recharge" these primary cells at home. Benefits would be no need to transport the raw aluminum from factory to home in battery format. Similarly for disposal.

Not so much a new cell chemistry as a new concept in rebuild ability, has anyone seen the BMS & is it of a type that aids identification of a suspect cell or other fault finding problems, just wondered what others thought of the concept, pity it is only made as a 48v pack, please move if I posted it in the wrong place, good concept??

there are BMSs now available that allow you to record internal resistance of the cell and you can track that during the charging cycle to flag cells which are showing rising internal resistance and that is the best clue you can use to determine what the cell is doing over time....

look at the D141 from bestechpower. it requires programming to dump the data to the computer. but limited to 13S, but you could use 2 in series for 26S.
 
You just don't "read" cleantechnica, you strap your self in and feel the G's! :)

Lithium Ion Batteries Get Big Performance Boost From Wonder Material Known As… Sand.

Only loosely reading this but spotted this, "Coulombic efficiency of 99.1% after 1000 cycles."

the researchers think that the lifespan of silicon-based electric vehicle batteries could be increased by as much as 300% or more

I never cease to be amazed at the progress being made.
 
Ah yes... and promised "advances" always happen... real soon now. Honest!

So the cells we use as hobby cells have gotten quite better... Then the NMC stuff is pretty amazing which is a good jump forward from that.

One problem a good friend pointed out is to characterize a battery and get accurate data from it they cycle it at 1c so that only gives you 12 cycles a day.
That means it takes 250 days to get to 3000 cycles... which is where the NMC in the zero is rated for 80% left or considered end of use.

To me this means when you want to change the chemistry a bit or try some new thing or something you start over. So you will find it takes a long time to sort out the crap and get a handle on what will make a good battery.

Disclaimer this is my interpretation of it all but I do try to understand you can't discover a new UBER awesome battery and sell it over night. This stuff really should take years and I'm ok with that because it lets me sleep without my house burnt down :mrgreen:

Yeah I know its good to be all dubious of this kind of news, but I know deep down inside you still want to know about it.
It made it on my favorite tech site as well so its getting picked up more this one.. http://www.fudzilla.com/home/item/35218-battery-designers-call-mr-sandman

I guess I just want to believe, just like the old X Files poster.
