LabRAM II coats LiNbO3 and Li2ZrO3 nanoparticles on NCM cathode material in seconds

Standard Li-ion batteries have many advantages. However, low power density and processing of flammable organic electrolytes are problems.

Commercialization of all-solid-state lithium batteries help the situation, considering their safety, wide operating temperature usage, and excellent fit for battery package formation. They enable growth in higher discharge applications like mass-market EVs and hybrids, and utility scale energy storage systems.

There are manufacturing challenges with these next-generation batteries, especially the processing of flame-retardant solid electrolytes. Our patented bladeless blending technology enables ultra-fast processing with mix-to-mix repeatability and significant cost savings vs legacy mixing methods.

Research shows the ResonantAcoustic® Mixer LabRAM II was able to coat LiNbO3 and Li2ZrO3 nanoparticles on NCM cathode material in a matter of seconds. The electrochemical properties were improved – the coated NCM material showed higher capacity than did bare NCM cathode material. In addition, direct contact with the sulfide-based solid electrolyte was suppressed, contact loss decreased, and the space-charge layer was eliminated.1
