Recently, it was learned from Jilin University that Lin Haibo's team from the School of Chemistry of Jilin University was the first in the world to prepare high-performance battery-grade carbon materials from rice husks, and used this material to develop cost-effective lead-carbon batteries, whose performance has reached the international advanced level
.
Recently, the scientific research results have built a 100-ton supercapacitor carbon and a thousand-ton battery carbon production line
.
Lead-acid batteries are one of the
most widely used batteries.
In 2005, scientists combined lead-acid batteries and supercapacitors to invent superbatteries (lead-carbon batteries), which significantly improve their performance compared with traditional lead-acid batteries
.
Lead-carbon batteries are known as a new generation of lead-acid batteries and are currently a research hotspot
in the field of international lead-acid batteries.
Lin Haibo introduced that the rice husk contains silica and carbon elements, and after removing silica, porous carbon can be formed, and then further activated, it becomes an activated carbon material
with great application value.
This activated carbon has a multi-level pore structure of macroporous, mesoporous and microporous, and has excellent electrochemical performance
.
Only rice husks can bring such wonderful effects, and other carbon materials such as coconut shells and palm shells do not have this multi-level pore structure
.
After more than 10 years of efforts, the team has overcome key technologies such as the green preparation process of biomass rice husk-based capacitive carbon, the carbon additive of rice husk-based battery and the anode of lead-carbon battery, and developed a cost-effective lead-carbon battery
.
Compared with ordinary lead-acid batteries, lead-carbon batteries have 6 times higher cycle life, 8 times higher charging speed, and 3 times higher discharge power, and have the advantage of
low cost.
