The use of earth abundant and renewable materials is encouraging for the future development of environmentally clean, safe and affordable electrodes for lithium- and sodium-ion batteries. Biohybrid electrodes based on lignin and several conducting polymers have been studied mainly for supercapacitor applications. Here, we show that biohybrid electrodes containing natural lignin and a PEDOT conjugated polymer serve as electroactive materials for lithium- and sodium-ion batteries using liquid organic electrolytes. A reversible discharge capacity of 74 mA h g⁻¹, at C/20 (4 mA g⁻¹) rate, was achieved in the voltage range between 1 V and 4.5 V, with peak values of up to 159 mA h g⁻¹. These properties make the natural lignin–PEDOT hybrid material a suitable organic positive electrode for Li- and Na-ion batteries.

用于有机电解质中锂和钠离子电池的混合生物聚合物电极†

对于未来发展用于锂离子和钠离子电池的环境清洁，安全和负担得起的电极，鼓励使用地球丰富的可再生材料令人鼓舞。已经研究了基于木质素和几种导电聚合物的生物混合电极，主要用于超级电容器应用。在这里，我们表明，含有天然木质素和PEDOT共轭聚合物的生物混合电极可作为使用液体有机电解质的锂离子和钠离子电池的电活性材料。在1 V至4.5 V的电压范围内，在C / 20（4 mA g ^-1）速率下可逆放电容量为74 mA hg ^-1，峰值高达159 mA hg ^-1。这些特性使天然木质素-PEDOT杂化材料成为锂离子和钠离子电池的合适有机正极。
