Influence of Organic Binders to the Properties of Lithium-Sulfur Batteries

Original language description

Advanced energy storage systems and electric vehicles play an increasingly important role nowadays and their role will be crucial for limitation of CO2 emissions in the future. These applications require higher energy density to cover future requirements such as longer range or more renewable energy stored for longer periods of time. Lithium-sulfur (Li-S) batteries can cover these requirements thanks to their several advantages such as high theoretical energy density (about 3000 Wh/kg), low cost of raw material and low environmental impact. However, Li-S batteries have also many drawbacks such as solubility of polysulfides in the electrolyte during discharging which leads to a decrease of capacity. Another obstacle is about 80% volume expansion of sulfur during cycling. This expansion leads to capacity decrease due to damage to the internal structure of the electrode. Another problem is the insulating nature of sulphur 2. There are several ways how these problems can be fixed. For example, preparation
