Biomass conversion into bio-based chemicals and high-value compounds (part 1)
Valorisation of Almond Shell Biomass into Battery-Grade Graphite via Low-Temperature Catalytic Graphitization
Short Introductive summary
This work explores the valorisation of almond nutshells, an abundant agricultural residue, as a renewable precursor for producing artificial graphite for lithium ion battery anodes. Biochar obtained from nutshells was catalytically graphitized using transition metals (Fe, Ni and Co) in two different biochar-to-catalyst ratios (1:1 and 1:0.6) at 1300?°C, drastically lower than those required for petroleum based graphite production. Iron proved to be the most effective catalyst, yielding highly ordered graphite providing a discharge capacity of 332 mAh g-1, comparable to commercial synthetic graphite and to petroleum coke graphitized at 2800?°C.
