Neo Battery forms partnership with Korea Zinc, Taesung

Executive Summary

• Neo Battery Materials Ltd. (via its subsidiary NBM Korea) has entered into a Memorandum of Understanding (MOU) with Korea Zinc Co. Ltd. and Taesung Co. Ltd. to accelerate the development and commercialization of composite copper current-collector foil technology.
• The partnership targets high-performance lithium-ion batteries for the drone, robotics, and micromobility sectors, aiming to reduce weight, lower costs, and enhance safety compared to conventional all-copper foils.
• The collaboration leverages Korea Zinc’s materials expertise, Taesung’s equipment technology, and Neo’s silicon anode products (NBMSiDE) to improve energy density and cycle life through synergistic material interactions.

Key Details

• Parties Involved: Neo Battery Materials Ltd. (via NBM Korea Co.), Korea Zinc Co. Ltd. (world’s largest non-ferrous metal smelter/refiner), and Taesung Co. Ltd. (advanced equipment technology manufacturer).
• Technology Focus: Composite copper current-collector (foil) technology for lithium-ion batteries.
• Technical Benefits:
  • Replaces central copper layer with polymer materials to reduce overall copper usage and battery weight.
  • Improves energy density for longer operating times in targeted applications.
  • Synergizes with high-capacity silicon anode materials (specifically Neo’s NBMSiDE) to mitigate mechanical strain, improving cycle life.
• MOU Scope & R&D Activities:
  • Optimization and validation of composite copper foil material performance.
  • Manufacturing and process optimization of bench-scale battery cell prototypes incorporating the technology.
  • Manufacturing of system-level battery prototypes for field demonstration and validation.
• Development Roadmap:
