Mix Diverse Battery Material Accurately and Consistently With Breathtaking Speed
ResonantAcoustic® Mixers (RAM) deliver cutting-edge performance for the battery industry, offering unmatched speed and efficiency in mixing advanced materials like solid-state battery components and nanocomposites. These battery mixers ensure precise, consistent results while minimizing solvent use and optimizing production processes.
Loaded Polymer Blending in Less than 3 Minutes!
To illustrate a heavily loaded polymer blend, two materials of very different particle sizes are blended with a polymer surrogate. This footage documents the nature of the material blending and integration into a heavily loaded (~85%) polymer based paste in just over 2 minutes! The use of RAM™ technology is ideally suited for loading of solids into polymers and mixing to a high rate of dispersion and consistent viscosity throughout the blend.
Dissimilar Powder Mixing in 10 Seconds!
Dry ingredients can be difficult to thoroughly and consistently mix, particularly when the particles are of different sizes and characteristics. To illustrate effective and rapid mixing, 10 grams of fumed silica is blended with 100 grams of sand in 10 seconds! Completed specimens exhibit no airborne fumed silica, demonstrating uniform blending at an order of magnitude difference in particle size.
Milling and Nano Coating in 8 Seconds!
Coating larger particles with smaller ones is a common processing application, and milling is often a part of the same process. In this video, agglomerated carbon black particles are simultaneously milled to nano size particles that coat the plastic pellets completely in just a few seconds. The high speed video clearly illustrates the dispersion of carbon black particles, their de-agglomeration, and progressive and comprehensive coating of the plastic pellets.

Solvent-free process for preparing lithium-ion batteries
WO FR FR31333709A1 French, Ohla, et al, Cabot Corp
Filed 2023-03-20 • Published 09-22-2023
A solvent-free process employs a multifunctional carbon black to prepare compositions and electrodes for lithium-ion batteries. The multifunctional carbon black provides two or more desirable characteristics, acting, for example, as a conductive carbon additive, as a fibrillation agent and/or as a mechanical reinforcement. In one example, an electroactive material, for example, graphite or a lithium transition metal compound, a binder and a multifunctional carbon black are combined in one or more steps. High shear mixing is used to process the binder in the presence of the multifunctional carbon black. The resulting composition can be formed into a film which can be applied to a suitable substrate to produce an electrode.
