Hybrid biopolymer electrodes for lithium- and sodium-ion batteries in organic electrolytes
Journal article, 2018

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.
