Understanding Biochar: Production and Propertties
Biochar is created by heating biomass - such as agritural residues, forstry trimings, or animal manure - in a low- oxygen environment, typically at temperature between 300 ° C and 700 ° C. This process, known as pyrolysis, decosposes the organic matter into three products: biochar (thee solid fraction), bio-oil, and syngas.

Biochar in Batteries
In lithium- ion and sodium- ion betaies, biocir is explored as an anode material. Te porous structure helps accompate volume changes during jon insertion and extraction, improvisin cycles life. Moreover, the disordered carbon structure in biochar can store ions contragh a combination of intercalation and adsorption mechanisms.
Studies show that biocir anodes can affect reversible capacities of 200-600 mAh / g for lithium-ion systems, and 150-400 mAh / g for sodium-ion systems. These values are competitive with graphite (372 mAh / g for lithium), and the low cost and regenerability of biochar offer clear presenages.
