New, cheaper and quicker way to produce activated carbon
Posted on: 22/Sep/2016 1:05:16 PM
Here is a new way to produce anode-grade porous, conducting activated carbon that can go into Li-ion batteries. Thanks to the tiresome efforts of expert researchers from NCL (National Chemical Laboratory), Pune, and IISER (Indian Institute of Science Education and Research). This new method they have discovered makes use of sugarcane bagasse to produce the material.
The present methods in use to produce anode-grade carbon are very time-consuming and pricey. At this juncture, this new production method discovered by Pune researchers makes use of power microwave system and yields topnotch carbon in a very short time span. The study results were published on 5th July in the journal Electrochimica Acta.
The choice of precursors and conversion process used to produce carbon from precursors decide the carbon quality used in electrodes. In general, anode-grade carbon is produced via decomposition at 1000 degree Celsius.
Prof. Satishchandra Ogale, the corresponding author of the Centre for Energy Science, IISER, Pune, and the formerly Chief Scientist of NCL, Pune, in his note said that the new method they have discovered makes use of only the commonly used microwave oven. They heat and combust the bagasse to obtain carbon materials of topnotch quality in just a few minutes.
There is a dramatic reduction in the overall processing time. At the same time, there is substantial reduction in electrical energy given as input, said Prof. Ogale.
