💡 AI + Research: The Future Is Here
EVA AI for Science will continue advancing innovation in Embodied AI for Science (EAI4S), working with leading research institutions to accelerate breakthroughs in materials for new energy, advanced materials, and other fields!
Designed specifically for researchers developing key lithium-ion battery materials, this system supports fully automated, end-to-end assembly of lithium-ion batteries, open-circuit voltage testing, and more
System highlights:
• Flexible robotic-arm design: A high-precision servo control system delivers micron-level positioning accuracy. Dedicated suction cups for different materials prevent cross-contamination while significantly improving coin-cell assembly accuracy and efficiency
• High-precision gantry transfer: Equipped with a high-precision gantry transfer system, the unit supports electrolyte barcode scanning, lid opening and closing, and high-precision electrolyte dispensing. It enables precise addition and traceability across multiple electrolyte batches while avoiding cross-contamination between different electrolytes
• Dual-vision recognition and calibration: High-resolution cameras and AI image-recognition algorithms identify the position and orientation of battery components and calibrate the robotic arm in real time. The system records alignment data for the cathode, anode, and separator of every coin cell; supports barcode scanning of positive shells; and records a unique ID for each cell to enable traceability of assembly data
• Automatic electrode weighing: A high-precision automated weighing system weighs electrode sheets automatically, records the electrode weight of every cell, and links it to the cell’s unique ID
• Self-cleaning sealing and pressing system: After a cell is sealed and pressed, the system automatically cleans the sealing and pressing mechanism to prevent lithium-salt precipitation from affecting assembly accuracy and to avoid electrolyte cross-contamination
• Open-circuit voltage testing:Finished cells undergo automatic open-circuit voltage testing to ensure that every cell meets performance requirements. Nonconforming cells are automatically screened out to ensure finished-product quality
