The researchers showed a safe, cost-effective battery capable of storing energy from intermittent sources of energy-

The mismatch between the availability of intermittent wind or sunlight and the variability of demand is a huge hurdle for us to get most of our power from renewable sources.
This problem can be solved by cost.
An effective way to store a large amount of electrical energy in order to deliver it over a long period of time when windisn does not blow and the sun does not shine.
In the operation of the battery, the electrons are cheap, the Earth-
Rich elements (
Carbon, oxygen, nitrogen, hydrogen, iron, potassium)

These compounds are nottoxic, non-
Flammable and widely used, safer and cheaper than other battery systems.

It can\'t catch fire--
It\'s big when you store a lot of electricity around people.
\"This new battery chemistry is made by post-
Dr. researcher Michael Marchak and graduate student kayxiang Lin and co-
Lead author Roy Gordon, Thomas Dudley Cabot, professor of chemistry at Harvard University and professor of materials science.
\"We combine a common organic dye with a cheap food additive, which increases our battery\'s kwh by about 50% over previous materials,\" Gordon said . \".
This discovery \"brought the first high

Electrode cells, similar to fuel cells, which store energy in liquids contained in external tanks. The tanks(

, Can be independent size.
Since the amount of energy that can be stored can be arbitrarily increased by only enlarging the size of the tank, it is possible to store more energy at a lower cost compared to conventional battery systems.
The active components of the electrolyte in most cell design are metal ions, such as vanadium dissolved in acid.
Metals can be expensive, corrosive, difficult to handle, and slow to move, resulting in low efficiency.
Last year, Aziz and his Harvard colleagues showed a mobile battery that replaced metal with organic batteries (carbon-based)
The molecule, known as quinones, is a rich natural chemical and is an integral part of biological processes such as photosynthesis and cell respiration.
When quinone in the solution forms the negative electrolyte side of the battery, the positive side depends on the traditional Bromo-
Bearing electrolyte used in several other batteries.
Harvard has authorized high-performance and low-cost technologies for a European company to have the potential to provide scalable grids
Toutilities-level storage solution.
However, the toxicity and volatility of Bromo make it the most suitable environment for the safe handling of well-trained professionals after the safety fence.
As a result, the team began to look for a new formula that could provide comparable storage advantages ---
Cheap, durable, efficient--

Lead author Deepak is currently an assistant professor of chemistry at the University of Colorado at Boulder.
Because it is very tightly bound to the iron in your body, it will kill you.
In ammonium ferrous, it has been combined with iron, so it is safe.
In the use of food additives and fertilizers, ferrous blue is usually used.
\"Because ferrous blue is highly dissolved and stable in alkaline solutions than in acidic solutions, the Harvard team pair it with a quainong compound that can be dissolved and stable under alkaline conditions, compared with the acid environment of the battery developed last year.
Deepak will be exposed to a concentrated alkaline solution compared to a damaged disposable AA battery.
\"It\'s not something you want to eat, it\'s not something you want to splash in, but other than that, it\'s really not a problem.
\"There are other advantages to using alkaline solutions.

The mobile battery system components are corrosive and can be built with simpler and cheaper materials such as plastic.
\"The first generation of mobile batteries is singleCouple elements-
Transition metals, such as vanadium, iron or chromium, \"said Michael Perry, head of the project for the electro-chemical systems at the Joint Technical Research Center, who was not involved in the work.
\"Now, we are looking for a possibility for us to get the features and attributes we want in a complete system.
More work needs to be done, but the Harvard team really proves the hope for the future --

A Distinguished University Professor, George.
Dively, an engineering professor at the University of Keswick Reserve, is another battery expert who is not part of Harvard research, and he agrees that the new technology has a significant advantage over other flowbatteries concepts, it includes \"potential very low cost for sustainable materials, high efficiency at actual power density, and safe and easy operation.
He added: \"It should be expected that there will be a brief development and scale of this mobile battery approach --

\"The Harvard technology development office has been working closely with the research team to address the changing complexity of the energy storage market and to build relationships with companies that have the ability to commercialize new chemicals.
The demand for battery storage is driven by regulatory factors such as economic factors.
In some states and many parts of the world, if solar energy cannot be used immediately by meeting the demand for electricity, solar energy on solar panels will be wasted unless electricity is stored.
In many states, however, under a regulatory plan called net metering, customers have the right to sell electricity generated by rooftop solar panels for high consumption.
In this case, consumers have little power to install batteries.
But market experts like William W.
Raymond prankke, Professor of Global Energy Policy at Harvard Kennedy School, believes that such a policy is ultimately \"uneconomical and unsustainable \".
\"As more homeowners install solar panels, utilities have raised objections to buying electricity from their customers.
Hogan said that net metering is one of a series of \"regulators designed to make solar energy more attractive,\" and predicted that consumers who eventually have rooftop photovoltaic panels will lose the option to exchange electricity for electricity discounts.
When this happens, these homeowners have the incentive to invest in battery storage.
Aziz and his harvardcolleagues\' design of the mobile battery provides potential advantages in cost and time, and it can maintain peak discharge power compared to lithium batteries.
\"This has potential because PV is getting softer and softer,\" Aziz said . \".
