The performance of every battery cell begins with the quality of its materials processing. Electrode slurry homogeneity, cathode coating uniformity, and binder distribution all directly determine energy density, cycle life, and rate performance — and none of them can be optimized with conventional mixing equipment. ResonantAcoustic® Mixing (RAM) is the battery material mixer that researchers and manufacturers worldwide have adopted to solve these challenges.
RAM's bladeless, non-contact mixing delivers uniform energy throughout the entire processing vessel, eliminating the particle damage, agglomeration, and inconsistent dispersion that plague high-shear mixers and ball mills. From lab-scale development to continuous production, RAM processes electrode slurries, cathode coatings, solid-state electrolytes, and end-of-life battery materials with a level of speed, uniformity, and repeatability that no conventional mixer can match. Here's why RAM is the battery material mixer driving next-generation energy storage:
- Bladeless, non-contact mixing — no impellers, no particle damage, no contamination
- Superior slurry homogeneity — single step uniformity
- Simultaneous multi-function processing — mix, mill, coat, and deagglomerate
- Mixing times reduced hours to minutes — without compromising quality or consistency
- Seamless scale-up — from milligrams to full production scale without re-optimization
- Continuous processing available — for high-throughput production
- Solvent-free processing — supports faster drying and dry electrode manufacturing
Battery Material Mixer Testimonials
…we have made our first steps with the new LabRam II from Resodyn Acoustic Mixers. With this second resonant acoustic mixer, we wereable to add another batch size to our large portfolio of different mixing technologies…”
- European battery materials research organization
“We work with multiple battery material mixes, including powder-powder, slurries and pastes. [RAM] gives us a quick, easy and convenient method of mixing, milling and sieving those materials in a single unit.”
- Global energy storage products company
“... the cathode exhibited a higher specific capacity and improved rate performance because of the minimal side reactions at the cathode−solid electrolyte interface. These results demonstrate the success of the Resonant Acoustic® coating of NiCo2S4 NPs on NCM 622.”

VALIDATING RAM FOR BATTERY MATERIAL PROCESSING
Switching your battery material mixer is a significant process decision. RAM is available for evaluation through a structured, low-risk process designed to build your confidence before you commit.
- Demonstration
A sales engineer will arrange an online demonstration via conference call to show you a lab scale version or
RAM so you can see for yourself how it works. In some locations, we can offer in-person visits. - Free material testing
We can arrange a free mix, coating, milling, or reaction test with your material or a suitable surrogate. You
send us the material, we process it, document it, and send it back to you for validation. Material SDS required,
no hazardous materials accepted. - Rental program
We offer the LabRAM I for a monthly rental, with the first month’s rent applying to the cost of a purchase. Try
RAM out in your lab and run as many tests as you would like. - Quotation
Once you have had time to evaluate RAM through either a demonstration, mix test, or rental, we will provide a
quote that matches your application needs, however simple or complex they may be. - Performance Testing
After purchase, we can also perform validation and testing (FAT, SAT, etc) of your new machine per your
requirements, including compliance, performance, quality, and safety tests prior to or post installation.
