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

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

• ptimized Wyon cell
