With the rapid advances in modern society, the demands for cutting-edge technologies have been increasing. Accordingly, studies to develop high-performance energy storage devices (ESDs) are being carried out, while the new types of ESDs have many obstacles to overcome, such as low round-trip energy efficiencies, poor cycling stabilities, and safety issues. In addition, an increase in the lithium supply and the development of infra technology have led to the sustainable expansion of LIB markets, requiring more advanced LIBs with higher energy and power densities as well as longer-term cycling performance. In this study, nanostructured carbon materials were fabricated from the bio-induced source, seaweed fulvescens. The nanocarbons showed high electrochemical performances as an active cathode material for lithium ion storage in a wide operating voltage window. Hence, the nanocarbon-based active cathode materials have a high potential in LIBs and lithium ion hybrid capacitors. |
