Project Name: TOB Empowers European Client to Establish 5MWh Automated High-Flexibility Li-ion and Na-ion Pouch Cell Mass Production Base
Description: From 2024 to 2025, TOB NEW ENERGY delivered Europe’s first 5MWh a year Li-ion pouch cell mass production line for a leading energy technology enterprise. The project provided full lifecycle services spanning facility planning, equipment customization, and technical training, enabling the client’s transition from lab-scale R&D to industrial-scale production. Featuring multi-chemistry process compatibility and pilot-scale readiness for solid-state electrolytes, the line passed acceptance with zero-incident delivery and 98% overall yield, setting a benchmark in the regional market.
Date: 2024 - 2025
Location: Europe
1. Rapid production launch: Dry room installation achieving -45°C dew point, completing facility construction to first cell rollout within 12 months.
2. Technology forward compatibility: Supporting current NMC system while reserving upgrade paths for sodium-ion batteries.
3. Harsh environment adaptation: Outdoor equipment rated for -30°C operation, compliant with local safety certifications.
4. Localized operation: Training client’s on-site team for independent production O&M (Operation & Maintenance).
5. Flexible capacity: Enabling small-batch multi-model orders (10+ cell variants with agile changeover).
