For the first time, polysaccharide-derived mesoporous carbonaceous materials (Starbon®) are used as carbon additives in Li-ion battery negative electrodes. A set of samples with pore volumes ranging from ≈0 to 0.91 cm³ g⁻¹ was prepared to evidence the role of porosity in such sustainable carbon additives. Both pore volume and pore diameter have been found crucial parameters for improving the electrodes performance e.g. reversible capacity. Mesoporous carbons with large pore volumes and pore diameters provide efficient pathways for both lithium ions and electrons as proven by the improved electrochemical performances of Li₄Ti₅O₁₂ (LTO) and TiO₂ based electrodes compared to conventional carbon additives. The mesopores provide easy access for the electrolyte to the active material surface, and the fibrous morphology favors the connection of active materials particles. These results suggest that polysaccharide-derived mesoporous carbonaceous materials are promising, sustainable carbon additives for Li-ion batteries.

可持续的多糖衍生介孔碳（Starbon®）作为锂离子电池负极中的添加剂†

首次将多糖衍生的介孔碳质材料（Starbon®）用作锂离子电池负极中的碳添加剂。制备了一组孔体积为≈0至0.91 cm ³ g ^-1的样品，以证明孔隙率在此类可持续碳添加剂中的作用。已经发现孔体积和孔径均是改善电极性能的关键参数，例如可逆容量。Li ₄ Ti ₅ O ₁₂（LTO）和TiO _2的电化学性能得到改善，证明具有大孔体积和孔径的中孔碳为锂离子和电子提供了有效的途径基电极与常规碳添加剂相比。中孔使电解质易于进入活性材料表面，并且纤维形态有利于活性材料颗粒的连接。这些结果表明，多糖来源的介孔碳质材料是有前途的，可持续的锂离子电池碳添加剂。
