Description
Summary:At present, the research on commercial lithium batteries is approaching a bottleneck, but people’s demand for energy storage technology is still increasing. Lithium-sulfur batteries have attracted widespread attention as they have a high theoretical energy density (2600 Wh/kg) and theoretical specific capacity (1675 m Ah/g). In addition, sulfur is abundant and non-toxic in nature, which makes it an environmentally friendly electrode active substance. However, there are still some problems, such as the volume expansion of the sulfur cathode, poor electrical conductivity, and the “shuttle effect” of polysulfides. It’s well known that the preparation of carbon cathode materials with excellent performance can effectively alleviate these problems. Starting from the different kinds of ingredients used in cathode materials, this paper reviews the recent research progress in the preparation of carbon cathode materials with fossil and mineral raw materials, biomass, and polymers. It is proposed to design and prepare carbon materials with special structures and dopant modifications to achieve excellent performance in lithium-sulfur batteries.
