Japanese researchers recently announced that they have developed a sponge-like carbon material
with a large number of nanoscale pores in a simple way.
The surface area of this carbon material is much larger than that of graphite of the same weight, and if it is used to make the electrodes of the battery, the battery capacity can be increased
.
Since manganese melts out of the alloy, researchers at Tohoku University in Japan put an alloy of carbon and manganese into a liquid metal bismuth that melts at 800 ° C, and a sponge-like carbon material
appears.
This carbon material also has strong corrosion resistance
.
Therefore, the capacity of the battery made from it will be larger and more durable
.
Previously, some researchers have developed sponge-like carbon materials, but they are difficult to produce
in large quantities due to the laborious production method.
The new method is to use alloy agglomerates to make sponge-like carbon materials, so it is easier to mass produce
.
The researchers plan to further increase the surface area and improve the conductivity of the carbon material, while improving the process of melting manganese from the alloy to reduce costs, and aim to provide samples
to companies and research institutions in six months.
