Deciphering the storage mechanism of biochar anchored with different morphology MnO as advanced anode material for lithium-ion batteries.

Biochar is regarded as a promising lithium-ion batteries anode material, owing to its high cost-effectiveness. However, the poor specific capacity and cycling stability have limited its practical applications. A straightforward and cost-efficient solvothermal method is presented for synthesizing MnO/biochar composites in this study.
