What is Lithium Sulfur material? Lithium Sulfur (Li-S) batteries are a growing alternative to lithium-ion batteries, offering higher energy density, reduced weight, and lower production cost. These batteries utilize sulfur at the cathode and lithium at the anode. To improve the battery’s performance, sulfur powder is often combined with conductive carbon powders, such as carbon black or graphite, which enhance conductivity. The precise handling of these powders is essential to ensure proper battery function and long-term stability.

Why are sulfur and carbon powders used in batteries?

Sulfur serves as the key cathode material due to its abundance and energy capacity. However, sulfur is not naturally conductive, so conductive carbon powders are mixed with sulfur to improve the electron flow during the charge and discharge cycles of the battery. These powders must be finely sieved, often below 10 microns, to ensure they perform efficiently in the battery. Achieving these fine particle sizes can be challenging with traditional screening methods, which is where Elcan’s advanced sieving technologies come in.
