Intensive Lab Mixer EL5

The Eirich Intensive Lab Mixer EL5 is a batch-based intensive lab mixer designed for wet and dry mixing processes in battery research and development. It mixes small batches of active materials, binders, additives and solvents into a homogeneous electrode slurry, or dry powders into a structured dry electrode mix. The usable capacity is 1.6 to 5 liters.

The EL5 is used in the Battery Cell Manufacturing Process, specifically Electrode Manufacturing: 1.1 Wet Mixing and 1.5 Dry Mixing/Coating.

Core Mixing Technology

Eirich mixers use a unique principle: a rotating mixing pan transports material to a high-speed rotor. This separates material transport from energy input, allowing for ultra-high shear or gentle homogenization in the same machine with fastest processing times. In addition, the mixing principle results in very low maintenance, and general wear is minimized significantly.

The laboratory mixers are specialized in dry carbon coating and PTFE fibrillation. High-shear forces break down binder fibrils to create a stable, solvent-free electrode "matrix", with higher torque for dry mixing.

Scale-Up & Process Validation

The laboratory mixers address "The Scaling Gap" (ensuring lab results match factory output) and enable solvent-free electrode manufacturing. Due to consistent mixing geometry, results from the EL1nano (0.1 L) or Intensive Lab Mixer EL5 (5 L) transfer linearly to production-scale volumes. Customers can perform 500 L trials using the Intensive Mixer RV12 to confirm product quality and cycle times under real-world industrial conditions at Eirich Test Center in Germany or at a dedicated partner like UKBIC.

Laboratory Mixer Series

The EL5 is part of the Eirich laboratory mixer series: EL1nano (0.1 L), EL1 (0.3 to 1 L), C5 (1.5 to 5 L), EL5 (5 L) and EL10 (10 L). The mixers are engineered and manufactured in Germany (Hardheim). More than 100 laboratory mixers have been delivered globally to OEMs, universities, and research institutes.
