They should be interesting, but they themselves
The balance motorcycle, often referred to as the "hovercraft", caught fire when people rode bicycles.
Some universities and airlines have banned them from entering the country. Their culprit? Lithium-ion batteries.
This widely used battery, the main force in the consumer electronics field, also caused a fire on electric cars and cargo machines.
Due to their risk of overheating, the company and the United StatesS.
The government has recalled thousands of batteries used in cameras, laptops, tablets, cordless tools and even winter jackets.
Researchers at Stanford may now have a solution.
In a study published on natural energy on Monday, they said they had developed the first lithium-
The ion battery is turned off before overheating and restarted immediately when the temperature cools.
Co-says there is considerable potential for mass production
Zhenan Bao, the author and professor of chemical engineering, pointed out that most of the materials involved are cheap plastic and nickel.
She said their batteries were restarted without losing efficiency.
Globally, researchers are racing to make better and cheaper batteries because demand for them is increasing.
With the new UN climate deal, countries are moving from fossil fuels to more batteries.
Electric vehicles are entering the market, and more solar panels and wind turbines are producing electricity that needs to be stored for a few days without sunlight or wind.
So scientists have come up with a lot of ideas.
On Monday, for example, a team at Lawrence Berkeley National Laboratory announced that it was working on a new approach that would make Catherine a key component of Batris that could improve performance.
Due to lingering safety issues, some studies are designed to reduce the risk of fire.
Last year, a team at Harvard University
Flammable mobile battery for storage grid
Scale the energy in the external liquid tank.
Researchers at the Massachusetts Institute of Technology published a paper
Ion batteries may be safer by making another key component, I . e. , electrolyte, solid, not liquid.
Others have studied the addition of flame retardant to the electrolyte, which carries charged particles between battery electrodes.
Last year, Yi Cui, an engineer at Stanford University, built a smart battery that warned before it was too hot.
For their new battery, researchers at Stanford University used a polyethylene film embedded in graphene nanoparticles. coated nickel.
Unfortunately, these technologies are irreversible, so the battery is no longer working after overheating, Cui said in announcing the latest research, of which he is a colleagueauthor.
To solve the big problem, he and his colleagues have become very small.
They turned to nanotechnology, a technology inspired by a wearable sensor recently invented by Baoan to monitor human temperature.
The sensor is made of plastic material embedded in tiny nickel particles, and the spikes of these nickel particles protrude from the surface.
For batteries, the Stanford team put the sharp nickel particles into the elastic polyethylene film and used graphene (an atom-
The carbon layer is thick.
In order to conduct electricity, the particles must be in contact with each other, but polyethylene stretches as the temperature rises, so the particles diffuse and the electricity no longer flows through the battery.
When the temperature drops, the plastic shrinks and the particles are re-touched.
According to the study, our design provides a reliable, fast and reversible strategy for high battery performance and improved safety.
George Crabtree, director of the Joint Center for Energy Storage Research at Argonne National Laboratory, said the study was "significant" and noted that "lithium-
Ion battery safety is the top priority of power transportation and power grid, and in power transportation and power grid, even the risk of several out-of-control fires can be an obstacle.
Crabtree said that while Stanford's "new concept" is impressive and promising, more testing is needed on larger battery systems running in many charging states
To make sure there are no unexpected problems, the diischarge loop.
He added: "Lithium

Ion batteries are made once a year and rarely cause melting, fire or explosion.
But there are also some high
Accident overview.
Those in the new popular "hovercraft" were accused of lighting several houses and even burning one in the state of Luis Anna.
While safer batteries may be on the road, entrepreneurs are not just waiting.
They are taking other steps to avoid a battery fire.
After lithium.
Several ion batteries in the Teslas were damaged in the crash and the car was on fire
Founder Elon Musk has announced that the company will add a titanium shield to the bottom of the Model S car.
