a rocket science solution to lithium-ion battery fires - li ion battery cell
I don't really drive enough to do electric cars (EV)
This is a compelling value proposition, but I will take it seriously if my commute is a bit longer.
However, one aspect of the electric car made me a little nervous.
Although rare, lithium
The ion battery may fail, causing a fire.
This fire can spread to other cells and eventually explode in the heat out of control.
This slight risk may make me think twice in the evening when charging the electric car in the garage.
There are potential solutions to this problem.
Last year, I wrote an article about the battery that can change the world, a story about the development of asolid --
If damaged, the state lithium battery will not catch fire.
However, today's lithium
The ion battery will not disappear soon.
As a result, a company has developed a potential solution to the fire caused by lithium
Ion battery failureCalifornia-
Based on KULR technology, working with NASA to develop a product that blocks lithium
The ion battery pack exploded in the heat out of control.
NASA is interested in the problem because it has the potential to lead to a catastrophic failure in space.
The runaway heat events of these batteries may be low
But on spaceships or spaceships, the consequences can be devastating.
The solutions that have been developed include placing a steaming capacitor next to a single battery.
If the battery fails, the temperature starts to rise rapidly and the heat will dissipate in the hot capacitor.
You can think that itas is similar to an electrical fuse that will not be able to stop the surge in current.
Except for the hot capacitor they call the Hydra thermal runaway shield (TRS)
, Each unit also contains firearms that prevent the fire from reaching the surrounding unit.
This solution prevents adjacent batteries from rising above 100 °c.
This is important because the possibility of short circuit in adjacent cells is greatly increased at temperatures above 30 °c.
You can see some demos of early NASA testing through TRS.
In this video, in 50-cell pack.
You can see the 2: 40 explosion in the video.
It was reported that the temperature of the trigger cell rose to more than 1000 °c, but the temperature of the adjacent cells remained below 100 °c.
Of course, it is necessary to better understand the root cause of these failures, as the number of these batteries in the app is growing exponentially.
When using billions of these cells, even a billion failures are unacceptable.
As these battery packs become more powerful-
And with high potential-
Consequences like a plane fire-
The demand for fire fighting will increase. The long-
Range solutions may be a new type of battery, but the solutions developed by kulr and NASA can greatly improve the safety of existing lithium
Ion battery pack.
