Thread for new battery breakthrough PR releases

[DVDRW]

In theory
Why 55ah cell is 2x more expensive than 40ah cell $/wh?

LTO is 4x heavier than INR18650 so more ebike parts/tires have to be replaced over time too.
And riding very heavy ebike not so pleasant

LTO is good for offgrid systems when price come down i think.

"Sodium-ion batteries 'set to challenge' dominant lithium-ion technology
http://www.theengineer.co.uk/energy...minant-lithium-ion-technology/1020369.article
(No mention of Faradion yet in ES search.)

...and now "Faradion Leads Energy Storage Trio Into Sodium-Ion Territory"
https://cleantechnica.com/2016/03/14/solar-energy-storage-targeted-by-sodium-ion-trio/

With a cost estimated at about 30 percent less than comparable lithium-ion batteries, sodium-ion technology could shake up the home and commercial energy storage marketplace.

Hehe... Good spotting/good point. Here says only about 150 Whr/kg. for LiFePO4:

Perhaps somebuddy misread the graph and took the number for Wh/L?

I just noticed that high capacity batteries (200-260 Wh/kg) reached interesting cost of 400$/kWh. I thought they still were around 1000-1500 Wh/kg!

I found another amazing thing: volumetric density reached the incredible value of 760 Wh/L!
This would mean storing 12 kWh in my e-scooter, currently carrying just 2 kWh! (270 km range! )
It's possible thanks to new nickel chemistry (LG INR18650-MJ1 3500mAh - 10A and Panasonic NCR18650B 3350mAh - 6.7A)
This chemistry is also as safe as LiFePO4, although more powerful and "dense" than old ICR (=LiPo/LiCoO2).

Ha ha ha. That's what I thinking!

This smells like a desperate capital raising attempt by the same people who bought us the Qant ... no wait, "by the same people who DIDN'T bring us the Qant".

Actually, I have no interest in this product at all. It seems to be a "fuel" which we will have to pay to refill a "tank", and I am fairly sure "harmless water dust" is actually code for "horrible environmental disaster".

However, if it was a proper flow cell battery without emissions ....

Interesting one to keep an eye on...
Grabat. http://grabat.es/#bateria
A Spanish battery manufacturer who claims to have a 2.3volt graphine cell with a energy density of 1000Whr/kg
.....and will be in commercial production by the end of 2016 !
...if only it can be true for once !

..
Graphenano, the Spain-based manufacturer of graphene, announced the installation of a manufacturing plant for batteries with Graphene Polymer in Yecla, (Murcia) Spain.
..This plant will reportedly host twenty assembly and manufacturing lines of high added value batteries which should produce, at full capacity, more than a million cells. The production of the first cells in this plant is foreseen for the months of January and February, and will be at full capacity in the second half of the next year.
The plant, which is over 7.000m2 in size, will enjoy the latest technology for the manufacturing of this new kind of batteries, equipment designed specifically for this development. The company's polymer for battery cathodes is said to improve the safety when using it, since they do not produce gases, do not explode and get less hot, in addition to being the only batteries in the world that keep working after being short-circuited. Certification tests carried out in close collaboration with the independent Dekra institutes in Spain (AT4 wireless) and TuV in Germany have exceeded 1000 Wh/kg, which is five times more than the current battery technologies.

The polymer itself has been researched, developed and tested for the last three years and is the result of an agreement signed by Graphenano, Grabat Energy and the group of chemistry of the university of Cordoba. Graphenano stated that it has reached agreements with leading multinational companies in fields like aerospace, automotive, renewable energies and others, which will benefit from this new technology.

Grabat.."snake oil ". .?
http://www.greentechmedia.com/articles/read/graphene-battery-too-good-to-be-true

Graphenano will be offering three types of batteries within months via its subsidiary, each composed of its graphene-based modular cells -- one for electric bicycles, another designed for motorbikes, and a third for stationary domestic storage.

Full production will be underway by October, with Grabat’s projected 200 employees producing 80 million cells per year at the company’s factory in Yecla in the Spanish region of Murcia.

The business has secured a fair amount of financial backing. Chinese electrical transmission and distribution company Chint has paid 18 million euros ($20 million) for a 10 percent stake in the company.

Martínez and one of China’s richest men, Nan Cunhui, attended the recent press launch -- along with Spain’s minister of industry. At the event, Martínez proudly displayed the company’s TÜV certification alongside impressive-looking battery prototypes and a well-produced corporate video.

Unsurprisingly, the Graphenano phenomenon has attracted plenty of media interest in Spain. Heavyweight national daily El Mundo ran an enthusiastic article on the company. Martínez has appeared on both local and national radio, expounding the merits of graphene-based energy storage and repeating his claims for his batteries.

But do these claims stand up to solid scrutiny?

Professor Andrea Ferrari, director of Cambridge University’s Graphene Center and chairman of the executive board of the European-Union-funded Graphene Flagship project, is skeptical of the batteries. But he does think it's possible for a company to be producing large quantities of graphene for use in them.

Although producing "true" monolayer graphene is still highly expensive, there are other less-tricky-to-prepare types of graphene -- such as platelets -- that could be manufactured cost-effectively.

Uncertainty surrounds the true nature of Graphenano’s cells, or what industrial technique the company is using to produce graphene. Although Martínez alluded to gas deposition onto a copper substrate in a radio interview, he claims this is just one technique employed by the company. Graphenano did not respond to a GTM request for clarification.

So is it credible that a company can be weeks away from utilizing graphene to produce a better battery commercially? And if so, how much better could that battery really be?

Jesús de la Fuente, founder and CEO of the respected Spanish graphene company Graphenea, confirmed that research is being carried out into replacing carbon black with graphene in lithium-ion battery electrodes. However, he said, this would only bring about modest improvements in battery performance.

The real breakthrough, explained de la Fuente, could be in so-called “post-lithium-ion” chemistries -- such as using graphene in the cathodes of lithium-sulfur cells. However, this type of technology is at least five years away from commercialization, he said. Anything even more innovative would likely be more than a decade away.

A number of influential blogs, such as Falacias Ecologistas, have been scathing in their assessment of the performance of Graphenano’s new batteries, using the Spanish expression "vendehúmos," or snake-oil salesman.

A senior figure in the graphene industry, speaking anonymously, pointed out that if such a revolutionary product were being produced, the company would be flourishing a sheaf of patents and white papers. Neither Graphenano or Grabat has publicly produced either.

“To make such a breakthrough, you would need a huge team of researchers -- at least a team of 100. This company says it has seven. There is no technical data and no support for their claims," said the source.

Furthermore, the TÜV certificate, proudly displayed at both the company’s media event and on its Facebook page, just seems to be the front page of a test report upon closer inspection.

María Buendía Bazán, a spokesperson with TÜV Rheinland’s Spanish marketing and communication department, said via email: “These companies are not certified by TÜV Rheinland.”

It is not impossible that Graphenano and Grabat could offer a groundbreaking product. But extraordinary claims require extraordinary evidence -- and that evidence has not yet been produced.

Allows lithium-ion batteries to be recharged hundreds of thousands of times.

CI chemist Reginald Penner (shown) and doctoral candidate Mya Le Thai have developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft.

Scientists have long sought to use nanowires in batteries. Thousands of times thinner than a human hair, they're highly conductive and feature a large surface area for the storage and transfer of electrons. However, these filaments are extremely fragile and don't hold up well to repeated discharging and recharging, or cycling. In a typical lithium-ion battery, they expand and grow brittle, which leads to cracking.

UCI researchers have solved this problem by coating a gold nanowire in a manganese dioxide shell and encasing the assembly in an electrolyte made of a Plexiglas-like gel. The combination is reliable and resistant to failure.

The study leader, UCI doctoral candidate Mya Le Thai, cycled the testing electrode up to 200,000 times over three months without detecting any loss of capacity or power and without fracturing any nanowires. The findings were published today in the American Chemical Society's Energy Letters.

Hard work combined with serendipity paid off in this case, according to senior author Reginald Penner.

"Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it," said Penner, chair of UCI's chemistry department. "She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity."

"That was crazy," he added, "because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most."

The researchers think the goo plasticizes the metal oxide in the battery and gives it flexibility, preventing cracking.

"The coated electrode holds its shape much better, making it a more reliable option," Thai said. "This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality."

The study was conducted in coordination with the Nanostructures for Electrical Energy Storage Energy Frontier Research Center at the University of Maryland, with funding from the Basic Energy Sciences division of the U.S. Department of Energy.

I searched ES and didn't see this one, but I bet somebody posted about it somewhere...

It's called the Johnson thermoelectric energy converter (JTEC). Not a battery (OK, off topic a bit) but a generator that converts heat into electricity.
They claim efficiency of nearly 60%, making it about twice as efficient as an internal combustion engine. No moving parts either.

https://en.wikipedia.org/wiki/Johnson_thermoelectric_energy_converter

http://johnsonems.com/our-technology/

The Johnson Thermo-Electrochemical Convertor (JTEC) is an all solid-state device that operates on the Ericsson cycle. Equivalent to Carnot, the Ericsson Cycle offers the maximum theoretical efficiency available from a converter operating between two temperatures. The JTEC system utilizes the electro-chemical potential of fluid pressure applied across a proton conductive membrane (PCM). The membrane and a pair of electrodes form a Membrane Electrode Assembly (MEA) similar to those used in fuel cells. However, in the JTEC the hydrogen circulates continually inside the device, which is different from a fuel cell in which hydrogen is consumed and must be continually replenished.

This reminds me of an air conditioner I saw in an old book at the Phoenix public library. It used no moving parts, heat as the energy input and 'hydrogen valving'. I think it was from the 40's or 50's.

Mmmmm... "Cheaper, smaller, safer"... batteries.

https://en.wikipedia.org/wiki/Magnesium

Magnesium is the eighth most abundant element in the Earth's crust and the fourth most common element in the Earth (after iron, oxygen and silicon), making up 13% of the planet's mass and a large fraction of the planet's mantle. It is the third most abundant element dissolved in seawater, after sodium and chlorine.

Mmmm... Nice.
