Pilot PVD Li Roll-to-Roll Vacuum Coater Z2P150H OVERVIEW ISO 9001:2015, 14001:2015 Certified 1. APPLICATION & DEVELOPMENT 1.1 R&D roll-to-roll vacuum coater Z2P150H (hereinafter – "the coater") is a complete system designed to deposit metallic lithium coatings by means of thermal evaporation. 1.3 The coater can produce either a single-sided coating in one or two deposition zones, or a double-sided coating without breaking the vacuum. 1.4 The design of this coater is based on Sidrabe’s practical experience in vacuum web coaters and processes development as well as R&D results, obtained in Sidrabe’s Research Department. 1.5 The coater operates in laboratory of Sidrabe’s R&D department. It is used for Li deposition technology scaling and manufacturing of trial batches of Li coated material. www.sidrabe.com Page 2 of 14

Pilot PVD Li Roll-to-Roll Vacuum Coater Z2P150H OVERVIEW ISO 9001:2015, 14001:2015 Certified 2. MAIN FEATURES OF THE COATER 2.1. The coater is a batch-operating plant with web roll loading before cycle and product roll unloading after the cycle. 2.2. The coater consists of 1 chamber, incorporating winding device, 2 process drums, pre-treatment sources, 2 thermal evaporation zones, pumping station and control desk. 2.3. Thermal evaporation zones are equipped with a closed-loop controlled electrically heated crucibles and shutters. 2.4. Process drums incorporate cooling channels and argon-venting for heat contact between substrate and drum surface. 2.5. The coater is designed to run in either single-sided or dual-sided deposition modes. 2.6. A blind flange and mounting area is foreseen for future upgrades, for example a planar magnetron. 2.7. The web winding system is capable of handling thin metallic foils and provides tension separation between the unwinder and rewinder zones. 2.8. Interleaf pre-treatment is performed by glow-discharge. 2.9. The pumping station is based on the usage of turbo-molecular pumps and combination of Roots and rotary vane pumps. 2.10. Operator interface uses a PC-based HMI. 2.11. Coater control is accomplished by a system of PLCs. www.sidrabe.com Page 3 of 14
