The United States successfully developed a new silicon anode lithium battery, and the charging speed increased by 16 times

Recently, researchers at the University of California, Riverside successfully developed a new architecture of silicon anodes, which can make the charging process 16 times
faster when applied in lithium batteries.

Due to the wide application of lithium batteries, a lot of research has been carried out to improve their performance
.
The search for "perfect" electrode materials never
stops.
Studies have found that silicon is a better battery cathode material, providing more than 10 times the performance
compared to current commercial batteries.
Since silicon and lithium react inside the battery, it expands to 4 times the normal size, so directly using silicon anodes does not work properly
within the existing lithium battery structure.

The researchers first constructed a layer of graphene sheets, and on this basis, they used columnar carbon nanotubes to construct columnar nanostructures
.
Finally, they used a gentle inductively coupled plasma to turn their columnar nanotubes into a tapered structure, on which they deposited amorphous silicon
.
Silicon anode lithium batteries using this structure also show extremely high stability
in fast charge-discharge cycles.
If this battery technology can be mass-produced, it is believed that the impact on the smartphone and electric vehicle industries will be huge
