MIT Just Had a Battery Breakthrough

Last week, researchers at the Massachusetts Institute of Technology (MIT) reported progress on what may be a huge step in that direction.

On October 11, MIT-based (and U.S. Department of Energy-funded) researchers reported that they have developed an “air breathing” battery capable of storing electricity for long periods of time at about $20 a kWh.

The technical paper can be found here.

MIT’s news release, meanwhile, puts it this way:

For its anode, the rechargeable flow battery uses cheap, abundant sulfur dissolved in water. An aerated liquid salt solution in the cathode continuously takes in and releases oxygen that balances charge as ions shuttle between the electrodes. Oxygen flowing into the cathode causes the anode to discharge electrons to an external circuit. Oxygen flowing out sends electrons back to the anode, recharging the battery.

Sounds strangely familiar to the 12-year old lurking somewhere in my memory.

One principal of the MIT project put it this way: “This battery literally inhales and exhales air, but it doesn’t exhale carbon dioxide, like humans – it exhales oxygen.”

Here’s what that means…

New Battery Technology is Dirt-Cheap – and Very Efficient

According to the researchers, a major issue with batteries has been the need to synthesize materials to increase the energy density of batteries (how much power you can store in a battery of a given size).

We can do it, but the materials required are inordinately expensive.

That’s where this air-breathing battery comes in.

By relying on sulfur and air, it’s dirt cheap.

The total chemical cost of this system is about 3% that of a lithium battery, but can store electricity for prolonged periods of time for a fraction of the cost now required by less efficient systems.

It’s a “flow battery,” where electrolytes are continuously pumped through electrodes and travel through a reaction cell to create charge or discharge.

Only this time, unlike with my winning experiment from when I was 12, the power contained in the system can light more than one light bulb.

Actually, it can light a lot of them.

And because the battery uses ultra-low-cost materials, its chemical cost is one of the lowest – if not the lowest – of any rechargeable battery to enable cost-effective, long-duration discharge.

Its energy density is slightly lower than today’s lithium-ion batteries, however, meaning that it takes up slightly more space per unit of energy.

While lithium-sulfur and lithium-air batteries exist today, the key innovation of the MIT research is combining the two to create a lower-cost battery with comparable efficiency and energy density.

Here’s the other neat consideration: Flow batteries are highly scalable, providing the ability to structure much larger systems than the current prototype (about the size of a coffee cup).

And here is where the connection to renewable sources comes into play: As the battery can discharge over months, it would be an excellent way for storing electricity from unpredictable sources like solar and wind.

Now if only I had patented my little “flicker tickler…”;

Singapore plans to develop solar power and energy-storage technologies as the oil-trading hub of Asia pushes to generate more of its power from renewable sources.

The city-state is testing floating power projects in its reservoirs, a technology that could help solar meet as much as a quarter of electricity demand by 2025, Deputy Prime Minister Teo Chee Hean said Monday in a speech opening Singapore International Energy Week. The government also reached agreements for energy storage and micro-grid projects, Sim Ann, senior minister of state for trade and ministry, said at the event.

In 5 Years, Batteries Will Blanket The U.S., Duke Executive Says


"There's going to be a lot of excitement around batteries in the next five years. And I would say that the country will get blanketed with projects," said Spencer Hanes, a managing director of business development with the Charlotte, North Carolina-based utility.

good read Shavian...

“Whilst lithium batteries are able to deliver high power requirements, they can only be used for short periods and their usage must be carefully managed, due to their short life span,” redT says on its website in an October 3 release on the Monash project.

“Flow machines, by comparison …have electrolyte that never degrades and are therefore well suited to high-energy applications over many hours, like ‘solar firming’, which involve heavy daily cycling.

“Combined, the flow machine can act as the ‘workhorseR17;, doing ~80 per cent of the work each day, whilst the lithium element can be used infrequently to provide the final ~20 per cent of the power requirements,” redT said.

Please be aware and spread the word you may save a child,s life, I did post a picture the last time I posted on the subject, much to the disgust of some readers, but if it saves a child,s life who really cares !!!

button batteries and lithium coin batteries are the small, round, batteries you find in toys, cards, watches, key fobs, calculators, hearing aids and numerous other everyday objects.

They appear to be pretty harmless and you would think that if they were swallowed, that they would pass straight through and out the other end.

Sadly, this is not the case and hospitals are reporting an increase in life-changing injuries resulting from these innocuous looking culprits.

you can read the full story here, it may save a life, please take note..

This will also extend to lithium storage battery,s

Responding to the UK government’s commitment to ban all new petrol and diesel cars and vans from 2040, Mark Dummett, Business and Human Rights Researcher at Amnesty International, said:

“This is good news for the environment and for air quality, but drivers should be aware that while electric cars may be green, they’re not always clean.

“Our research shows that there is a significant risk of cobalt mined by children and adults in appalling conditions in the Democratic Republic of Congo ending up in the batteries of electric cars. Workers in the DRC, earning as little as one dollar a day and at risk of fatal accidents and illness, must not pay the price for the UK’s shift to electric cars.

“Drivers will want to know that their new cars are not linked to the suffering of child labourers in the DRC, but there is a worrying lack of transparency across the car manufacturing industry, with many leading names failing to disclose information about their cobalt supply chains.

Cobalt on the London Metal Exchange traded at about $32,000 a ton at the end of 2016, up 36 percent from the previous year, and has rallied about 65 percent to more than $56,000 a ton this year. That’s equivalent to more than $25.40 a pound. They’re likely to double in 2017 and may remain above $20 a pound through the end of the decade, CRU’s Spencer said.

A typical electric car battery contains 15 kilograms of cobalt, while a laptop needs around 33 grams and a smartphone requires 6 grams, according to Sydney-based project developer Cobalt Blue Holdings Ltd.

Congo is under pressure to restrict artisanal mining, including in the cobalt sector, which a 2016 Amnesty International report said has a prevalent use of child labor. Tesla Motors Inc., among the largest consumers, undertook in 2014 to only source the metal from North American miners because of supply-chain concerns. Apple Inc. said in March it had expanded responsible sourcing efforts beyond conflict minerals to include cobalt.

so that would be 3 REDT containers a concrete slab and one reel of cable and $380 a Kwh... $300 a Kwh if they leased the electrolyte....

A tesla powerwall fitted cost around £500 a Kwh fitted... looks like Tesla could be a tad expensive....

With cobalt and lithium prices set to rocket, looks like Elon Musk has shot himself in the foot...the more cars they produce so increases the demand for lithium and cobalt and up goes the price.....so the price of lithium battery,s will have to increase...the price of lithium has doubled over the last 12 months and cobalt...Cobalt prices have climbed 71 percent so far this year.....wait till production of electric cars starts to really kick in and the prices of those metals will rocket... Chinese set to start mass production of electric cars along with a few others.....metal prices set to boom !!! can lithium and cobalt supply both industries ?? the car and storage??? that remains to be seen...

[dlg3] 21/10/2017 23:28

the above must include infrastructure costs.... still pretty pricey !!

a concrete slab and a few reels of cable...... must be all the air-con and fire suppressant equipment...

[dlg3] 21/10/2017 23:20

the Tesla battery is costing $3000 a kwh

Green Mountain Power wants to build Vermont's second commercial renewable energy storage battery near its solar array in Panton.

The $3 million Tesla battery will store about 1 megawatt of power which will come off of the solar array nearby.


Batteries don't store power. They store energy. I would presume it is 1 MWh of energy!!! sounds pretty expensive !!!

Bushveld Minerals (BMN) RNS from yesterday....."Whilst the demand for vanadium remains largely anchored in a slow growing steel industry, Bushveld Minerals believes there is a strong potential for imminent significant global vanadium demand surge from the fast-growing energy storage market, particularly through the use and adoption of Vanadium Redox Flow Batteries."

Amazon has powered up its largest ever wind farm in Texas.

It consists of 100 turbines and is part of the web giant’s target of delivering 100% renewable energy for its data centres.

It takes the company’s clean energy projects to 18 across the US, with the firm now generating enough clean electricity to power 330,000 homes every year.
