Some time ago, due to the unstable lithium battery of mobile phones, the explosion and spontaneous combustion of mobile phones have emerged one after another.
I still vaguely remember the fear of being dominated by a certain star’s mobile phone explosion. . .
But scientists have never given up treatment.
A few days ago, scientists from China and the United States have collaborated to complete a study in which they put nano-scale diamond particles in the electrolyte of a lithium battery.
These particles effectively prevent the formation of short-circuit deposits inside the battery, thereby eliminating the hidden danger of fire to the greatest extent.
Lithium batteries have a wide range of applications. They have high density, strong charge and discharge performance, and almost have an irreplaceable position in the industrial and consumer-level fields.
However, if lithium metal with high purity is used as the electrode, it is easy to generate deposits called "dendrites" inside the battery. These deposits will accumulate over time. After reaching a certain level, it will cause the whole Short circuit of the battery.
Current lithium batteries generally use graphite materials as electrodes, which can reduce the production of "dendrites" to a certain extent, but graphite will reduce the energy storage effect of the battery. With graphite and without graphite, the energy storage effect of lithium batteries is similar. ten times.
The use of nano-grade diamond particles for addition, the researchers found that this not only reduces the production of "dendrites", but also maximizes the energy storage performance of the battery.
Moreover, this extremely small particle has a very low manufacturing cost and has a high value in commercial applications.
In the next step, researchers will conduct a series of experiments in the consumer-level field to verify the value of this material.
Perhaps soon, our mobile phones will be able to use this cheap and efficient energy storage method.
