After studying more than 22,500 battery components, DOE researchers have identified two prototypes that they believe can go beyond lithium --
The person in charge of the project announced that the cost of the project was much lower.
Joint Center for Energy Storage Research (JCESR)
The innovation center of Argonne National Laboratory will store and perfect lithium for the grid-
Prototype of sulfur for transportation.
JCESRwill will test the prototypes to demonstrate that they can achieve the goal of creating the project: to increase the energy density of commercial batteries by 5 times
And fifth, they cost 2011.
New batteries will cost less than $100/kWh at the time of commercial promotion.
\"All-cell testing of these concepts is now under way and provesof-
George Crabtree saidin, director of JCESR, released \"director information\" on the project website last week will be evaluated soon.
Grid storage is risky for the gridlevel storage.
With viablegrid-
With normal batteries, utilities can smooth the variability of wind and solar energy without relying on natural gas or nuclear power plants.
To meet these needs, the battery has to store a lot of energy cheaply.
Cost of lithium-
Ion has fallen sharply, which makes it competitive in some markets, but JCESR is keen to get a fraction of these products. The redox-
Fluid prototypes replace solids in lithium
Ion batteries that inject liquid into organic molecules carry charge when they flow through the battery.
Crabtree says organic molecules are cheap, recyclable and harmless to the environment.
\"The biggest advantage of doing this is --
Crabtree said in a recent appearance at Carnegie: \"The so-called mobile battery is scalable, so if I enlarge the tank of active ions by 10 times, I can store 10 times the energy
University of Mellon
\"You can\'t do this with lithium --ion battery.
\"Organic molecules will be connected together to form particles large enough to be blocked by porous membranes, which will separate the charged particles in the liquid from the uncharged particles.
\"If there is a cross switch, you are basically short-circuiting the battery,\" he said . \".
So you always want
Let them separate).
If the molecules are large enough, you can do it with a very cheap Porous Filter.
\"Transport lithium-
Sulfur batteries are known for exceeding the energy density of lithium
This makes them promising in transportation.
The weight of the electric vehicle transport battery consumes too much energy, and light batteries are needed for aircraft flight.
But lithium
The sulfur battery that exists today has a low cycle life
The number of times they can charge before they fail.
JCESR begins to improve cycle life while optimizing lithium
Advantages of sulfur
Increase energy density and make the battery lighter.
\"The way we deal with this challenge is to fundamentally redesign the electrolyte.
Kevin Zavadil, a technician, said on Argonnevideo.
\"What we\'re specifically looking for is to create an electrolyte that can support the rate type, the power we need, and the energy content we\'re trying to achieve.
Successful lithium
Sulfur cells can maintain five times the theoretical energy density of lithium
Crabtree says the ion is twice the actual energy density of lithium
Ion batteries used today.
In an appearance at the University of Chicago a year ago, Crabtree revealed that JCESRhad narrowed the search range from thousands of possibilities to only four batteries.
When he debuted at Carnegie Mellon University in October, he was still talking about four people.
The JCESR team believes that the two selected prototypes are most likely to achieve \"the goal of packaging level of $100/kWh \". . .
To the five ends of JCESR
He said last week, but the two runners --
There is still hope. The runners-up are an air-
Breathing water sulfur batteries for power grid storage and multi-price magnesium batteries for transportation.
Crabtree called the water sulfur battery \"very smart \".
\"The idea of this battery is that it\'s cheap.
So in this case it actually uses sulfur as the anode, not the cathode.
Sulfur is very cheap and rich.
It takes water as an electrolyte.
Nothing is cheaper than water.
So the fact that this is so cheap means that it may be able to compete with pumped hydro for storage costs and, in fact, it may be so cheap that it is able to achieve seasonal energy storage, for example, you store solar energy in the summer and use solar energy in the winter.
\"The water sulfur battery is the five-
The team\'s lab was reviewed at the end of 2015.
The principle of multivalent magnesium batteries is that if lithium contains a positive ion, an element containing two or three positive ions will have two or three times the energy storage capacity.
Scientists have done battery experiments with calcium and zinc, and scientists at JCESR think magnesium is the most promising.
But no one can overcome these challenges yet.
\"Only a few people work with enough voltage, capacity and working ion mobility to meet the performance goals of JCESR,\" Crabtree said . \".
So JCESR plans to focus on the last year of five years. year mission.
\"In the remaining year, the research of JCESR will be mainly used to improve the prototype of the redox mobile battery of the power grid and lithium
Sulfur batteries for transportation.
In response to the reader\'s inquiry, Crabtree elaborated on his views on the scalability of mobile batteries and ordinary batterieslithium-
Ion: \"When the mobile battery is fully scalable (
It means that the volume is 10 times the energy)
It\'s not a lithium ion battery.
To increase the volume of lithium ion batteries by 10 times, the energy generated is far less than 10 times, because the fluidity of lithium ion in lithium ion batteries is limited, and it takes 10 times for lithium ion to pass through the cathode or anode.
However, this larger time interval may exceed the time of charge or discharge, so the full volume of the cathode or anode will not be accessed.
It seems.
It\'s intuitive at first glance, but it\'s common knowledge in the battery community.
This scalability is one of the most attractive features of the mobile battery to the grid, where a lot of energy is often required to be stored.
