Top-Class Volume-Specific Capacity: High-Capacity Anode Materials for Secondary Batteries
When using tin sulfide as the negative electrode material for lithium-ion batteries, the theoretical capacity of tin sulfide is 4.7 times that of graphite by volume and 2.1 times that of graphite by mass. In terms of actual discharge capacity by volume, our tin sulfide is a high-capacity negative electrode material on par with silicon-based negative electrode materials. It has also been reported to excel in fast charge and discharge performance. Additionally, since the elements that make up tin sulfide are sulfur and tin, which are abundant in nature, cost reduction during mass production is expected. This tin sulfide powder is a uniform mixture created by adding acetylene black, a conductive additive, to our developed tin sulfide dispersion with excellent dispersibility. Furthermore, changes in particle size, type of additives, and amount of additives can also be considered for this tin sulfide powder. Please feel free to contact us!
