What is the potential use of Klason lignin extracted from sunflower husks in the context of electrochemical applications?

Klason lignin is a type of lignin that can be extracted from plant materials such as sunflower husks. Lignin is a renewable and abundant natural resource with potential applications in electrochemical energy storage devices, such as lithium batteries. The study investigates whether Klason lignin can be used as a cathode-active material in primary lithium batteries.

Klason lignin extracted from sunflower husks can be used as a cathode-active material in primary lithium batteries. The study demonstrated that it has a maximum specific capacity of 380mAh g–1 at a current density of 25mA g–1, showing good prospects for use in low-rate, long-term power sources.
