Mercedes-Benz and University of Michigan Unveil New Method to Extract Superior Hard Carbon Anode from Rice Husks

[Overseas Hard Carbon Anode: Extracting Hard Carbon from Rice Husks] On December 7, 2024, according to a report on the Michigan Engineering website on December 5, the latest research by Mercedes-Benz and the University of Michigan revealed a new method for extracting hard carbon from rice husks. The battery anode made from this hard carbon outperforms traditional graphite anodes and is more sustainable.

Traditional lithium-ion batteries rely on graphite, which is import-dependent and causes significant carbon emissions. Rice husks, as a biomass raw material, offer a more sustainable alternative.

Through high-temperature processing, the carbon in rice husks is converted into hard carbon, which not only surpasses traditional graphite in performance but also demonstrates higher energy density in batteries. The study showed that the electrochemical performance of rice husk-derived hard carbon reaches 700mAh/g, far exceeding the 370mAh/g of traditional graphite.
