Reducing the Cost and Energy of Lithium-ion Battery Manufacturing using High Throughput Atomic Layer Deposition Processes

Forge Nano has recently developed an innovative strategy based on atomic layer deposition(ALD) of oxide coatings on battery separators and electrode materials. ORNL team worked with Forge Nano under this CRADA to construct larger format cells, validate battery and separator performance, and perform advanced materials characterization. It was observed that oxide coatings improve the battery cell performance in terms of both rate capability and long-term cyclic stability. ORNL team performed the research under this CRADA at DOE’s Battery Manufacturing Facility (BMF) at ORNL..
