Confidential, no rights for distribution Company | Technology | Products| Summary Manufacturing environment ▪ Production volume per cell type starting at 10k up to over 1 million units per year ▪ Full traceability per cell (medical field requirement) ▪ ISO class 7 clean room environment ▪ Production process inside glove boxes (no humidity) ▪ ISO 9001 certified, we develop and manufacture according to ISO 13485
Confidential, no rights for distribution Company | Technology | Products| Summary Certification & approvals • Performance: Capacity / resistance / cycle life / shelf life • Reliability: Ingress protection / drop / chemical resistance / pull force • Safety: IEC 62133 / UN DOT 38.3 • FDA: Approved together with device
Confidential, no rights for distribution Company | Technology| Products| Summary What makes us unique today ? 1. Plastic technology 2. Stack technology 3. Micro technology
Confidential, no rights for distribution Company | Technology| Products| Summary Plastic technology – Basics ▪ Only company in the world using just plastic casing for Li-ion cells ▪ Best customized shape possibilities in the market ▪ Maximum capacity for miniature cells (the smaller the more advantages the Wyon technology has) ▪ Biocompatible (direct contact to skin) ▪ Light weight ▪ No voltage potential on case ▪ Hermetically sealed
Confidential, no rights for distribution Company | Technology| Products| Summary Plastic technology – Benefit: High energy density ▪ Optimized to costumer design or available space ▪ Higher Capacity compared to standard button cell (max. volume used) Loosing space (energy) because of double housing and circular shape: standard button cell optimized Wyon cell
Confidential, no rights for distribution Company | Technology| Products| Summary Stack technology – Basics ▪ Flexible shape possibilities (curved, triangular, ring, etc.) ▪ High capacity achievable (use of free space) ▪ Small housing heights are possible ▪ High reliability and high security (precise alignment of anode/cathode)
Confidential, no rights for distribution Company | Technology| Products| Summary Stack technology – Benefit: High service life Cycle behaviour @ C/2; 100% DoD; RT 120 100 2k Cycle 90% initial C 80 % initial capacity 60 40 20 0 0 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 cycles Test done with Wyon B01 battery
