Company profiles Presently, carbon materials are widely used in negative electrode. Typical carbon materials are natural graphite, artificial graphite, hard / soft carbon and meso phase carbon. Dry grinding process has been widely used to manufacture these kinds of anode material. Silicon materials have recently risen due to its capability. It has high density and very low electric potential, very similar to graphite, so it can improve battery capacity. However, there are technical limitations, such as a high rate of volume expansion while charging it. One of possible solution is reducing the particle size down to nano range. Micro beads with diameter of 0.1mm and under in Wet grinding process has to be used to earn this super-fine grinding for particle size under 100nm. The NETZSCH ZETA RS is available to use diameter of 0.03 mm, grinding beads and increase the solid contents up to 30 wt. percent of metal silicon to achieve high productivity. The other main component of LiBs is the separator which impacts the output and safety. To increase the thermal stability and mechanical properties of the separator, ceramic coated separator (CCS) have been adapted. Generally, aluminum oxide is dispersed in acetone or water and the NETZSCH system ZETA mill has been used to make a homogenous dispersed slurry for coating process. In order to achieve high energy, high power, and high cyclability, the use of CNTs with its high electric conductivity and large specific area, is attractive for it to be used as a con- ductive additive. The use of CNT's show significant increase of performance of the LiBs, compared to classical conductive material like a carbon black and graphite particles. However, de-bundling of CNTs is very difficult due to its strong agglomerate tendency. Consider the process time and the NETZSCH Epsilon original characteristics of the product, it is limited to use conventional mixing and wet grinding machine. As an alternative possible solution, the NETZSCH inline-mixing system Epsilon and economic dispersionizer, OMEGA are highly recommended. The business unit "Grinding & Dispersing" of NETZSCH has a wide range of products, both dry & wet grinding, and dispersing & mixing processing technology for a variety of applications. NETZSCH has significantly invested in R&D and quality improvement processes to ensure we can provide a large number of state of the art machines in the LiBs industry.
