army scientists max out battery power to save soldiers' lives - 3.7 volt rechargeable lithium ion battery

ADELPHI, Md. U. S.
Soldiers carry an average of nearly 100 pounds of their equipment on the battlefield, including 19-and-
Battery 30 pounds.
Army Research Laboratory in Adelphi, Maryland
Scientists are trying to ease the burden.
And the military's carbon footprint.
"The energy density, the length of the battery duration, is a direct function of the voltage," said Cynthia Lundgren, head of the laboratory's electro-chemical department.
Notice typical stateof-the-
Art lithium ion battery production 3. 8 to 4.
"If we can get a voltage of 5 volts," she continued.
Then we can increase the density by 30% and reduce the load of soldiers.

"At the Department of Defense, our batteries need to operate in a wide temperature range and must be safe in a ballistic environment," Lundgren said . ", Added that their batteries must be in-
40 to 55 degrees Celsius.
These additives also enable the battery to survive more charging cycles before it is considered dead.

Battery with stable voltage
The first of its kind
The lab's material scientist, Arthur creez, said it can withstand hundreds of charges before it is less than 80% of its initial capacity.
"We can discharge the battery and charge it --
We can do it hundreds of times, "he said.
"So part of stability is not just being able to do it once or twice, but a lot.
"Rechargeable batteries that can be purchased at local pharmacies can be well equipped with lighter, longer batteries
Long-lasting materials created by scientists in a few years.

"To do this, we need a bigger battery.

"Call the soldiers again, call the front again-
She said: "The operating base is very expensive --
Fuel, especially the lives of soldiers. "One work-in-
Fuel cells for portable power supplies are making progress.
Although they "never were able to make it small enough to run on soldiers" due to peripheral gear, Lundgren said fuel cells on the base could charge the entire squad's batteries.
And through the contract with the Defense Advanced Research Project Bureau (DARPA)
The lab is working on making a fuel cell that runs on propane to power the drone.
"They have demonstrated an extension of flight time, from two hours of using batteries to eight hours of using fuel cells and propane," said Lundgren . ".
"This is amazing.
"Of course, you can't forget the sun when talking about alternative energy.
"The soldiers like their solar energy," Lundgren said . " He added that while the Department of Energy is "looking for large solar energy", the Pentagon is "looking for portable solar energy ".

Cynthia Lundgren, head of the electrical division of the Army Research Laboratory, presented the solar blanket for the proton Kes "power manager," which combines the energy extracted from the fuel cell, provide electricity in some of the most remote places in the world.
One of the laboratory's contractors, Protonex, is in the early stages of selling its "Power Manager" to PEO soldiers, "It combines the energy in the fuel cell with the solar blanket, provide electricity in some of the most remote places in the world.
"You can turn off the laptop and you can use it to charge a whole bunch of different batteries --
It has cables for everything, "said Lundgren.
The soldiers like these.
"It was only during the war in Afghanistan that the army began to give up primary batteries and switch to rechargeable ones.
But now that 50% of the troops are completely dependent on them, Lundgren said that next, the lab wants to use its research to create a fuel product that completely replaces batteries and charging devices on the battlefield.
"We want to make liquid fuels using sunlight, water, carbon waste," she said . ".
"The solar energy is great, but you can't store it at night.
That's why you have batteries, so you charge your batteries with solar energy.
If we can convert it into liquid fuel using solar energy, then the fuel can be stored.
Lundgren said that in order to liberate the soldier's ability to carry more water or ammunition, her team was mainly motivated by one thing: "Knowing that they come to work every day, one day they may save the lives of soldiers.
