NANTG ITALIA S.R.L

What NANTG ITALIA S.R.L does

NANTG ITALIA S.R.L is the wholly-owned Italian subsidiary of NantG Power, LLC (Delaware), operating as the European research and development hub in Milan for a silicon-dominant lithium-ion battery cell platform. Through its parent, the company develops high-energy-density battery cells in standardized 21700 cylindrical and pouch form factors, combining NMC cathodes with proprietary silicon-composite anodes. The platform is protected by a portfolio of registered patents covering SEI stabilization, silicon/carbon composite structures, swelling mitigation, high-rate charge/discharge architecture, high-loading electrodes, formation chemistry, silicon-optimized electrolytes, and a multi-tab/tabless design. AI-driven, data-guided optimization is applied to electrode loading, porosity, and formation processes.

The product family comprises four core SKUs: SiXXUS 1.0 (5.4 Ah, 21700), SiXXUS 2.0 (6.0 Ah, 21700), Olympic Flex (2–20 Ah configurable pouch), and Olympic XL (59/61 Ah large-format pouch). Claimed performance metrics include up to 373 Wh/kg energy density on Olympic XL, 8.5-minute 10–80% fast charge at 43–48A, up to 5C continuous discharge, and 1000–2000+ cycle life at 100% depth of discharge. The company sells to aerospace, defense, UAV, robotics, and high-performance EV manufacturers through a direct enterprise field-sales motion that runs on engineering sample requests and technical reviews; pricing is not publicly disclosed.

The company is privately held, with Dr. Patrick Soon-Shiong serving as Chairman and Dr. Fabio Albano as CTO and Co-Founder. Headcount is reported at 11–50 employees. No funding rounds, revenue, customer logos, certifications, or partnerships are disclosed in the available source material, and the commercial validation of the technology remains unverified by third parties at this stage.
